Altyn Raiders Altyn

Altun Mountain extends from northeast to east. Altun Mountain has three mountains and two valleys from south to north. There are nearly 30 peaks above 5000 meters above sea level on both sides of the ridge line in the main peak area, with an average elevation of 5200-5828 meters. Altun Mountain is 360 kilometers long from east to west and 0/90 kilometers wide from north to south, with a total area of 45,000 square kilometers, which is equivalent to the total land area of seven Shanghai cities.

Brief introduction of Altun Mountain

Altun Mountain is a mountain range in the southeast of Xinjiang Uygur Autonomous Region in China. The average height of Altun Mountain is 3000~4000 meters. The western section is higher, with the highest peak of 6161m.

There are small glaciers in Altun Mountain. Ruoqiang River, Milan River, etc. Originated here, but the amount of water is not large; Oases such as Ruoqiang and Milan in the foothills are very small. There are small glaciers. It will be reduced to less than 4000 meters, and the height of the junction of Xinjiang, Qinghai and Gansu provinces (regions) will be raised to 5798 meters. The climate is dry, vegetation is poor, and there are rivers in uncertain years.

Altun Mountain is connected to Qilian Mountain in the east, and the Dangjin Mountain Pass between the two mountains is the traffic artery between Qaidam Basin and Hexi Corridor, with a highway passing through it.

; Walking in the desert during the day, the clouds are densely covered, and the moon is dark and windy. The southern end of Tengger Desert is connected with Wuwei City, Gansu Province. Sand goes to the wall and sheep goes to the house. This place has become a nightmare for generations.

To stop desertification, we must first solidify the desert near urban and rural areas. In Wuwei, people solidify the desert by burying grass squares. Although the grass grid is effective, it is too inefficient to bury only one acre a day. Zhang Zhiming, deputy general manager of Gansu Jiantou and chairman of the equipment company, witnessed the consequences of desert invasion and the hardships of villagers in sand control. He had the idea of developing a sand control machine. 2065438+July 2004, Zhang Zhiming led the team to design and manufacture the world's first three-dimensional sand-fixing vehicle. The efficiency of mechanized sand control is 50-80 times that of manual sand control. In addition, the sand-fixing truck can reach the desert hinterland that human beings can reach, and at the same time, it can plant sand plants to realize the combination of engineering sand control and biological sand control.

In the past three years, three-dimensional sand-fixing vehicles have carried out mechanized operations in Liangzhou District, Minqin County and Gulang County of Wuwei City, and more than 4,000 acres of desert have been effectively managed. Its sand control base has also been rated as the national sand control experimental demonstration base (mechanical sand control project).

Since the efficiency of mechanical sand control is so high, can we go to desert control? Zhang Zhiming replied, we can. We can't completely control the desert. T, and it's unnecessary. People retreat into the sand and people retreat into the sand. This is not the best situation. Desert is naturally formed by the earth and is also a part of ecology. The key is not to let the desert expand uncontrollably. What we have to do is to ensure ecological balance.

At present, many countries and the Belt and Road have a strong interest in three-dimensional sand-fixing vehicles. This efficient sand control equipment made in China will enter more countries to help them resist desertification.

Dujiangyan in the desert guards Yangguan.

Wang Wei, some people say that people have no reason to go out of Yangguan in the west, but now they describe it as the city has no reason to go out of Yangguan in the west. Because the ancient city of Yangguan has been destroyed by floods and yellow sand, there are only a few beacon towers left.

Many people can. I don't understand how there can be a flood where the annual precipitation is only 39 mm. Because where does the rain and snow come from?

The dam desert of Kumtag Desert in Dujiangyan is 2 1 km long, which is very spectacular. After the project was completed, Yangguan was never flooded again. Especially 20 1 1. Dujiangyan, located in the desert, diverted disastrous floods and protected thousands of people's lives and property and 20 thousand mu of farmland in Yangguan.

Dujiangyan desert lies in scientific water diversion. It uses the 13 dam to transfer the instantaneous flood to the desert and store it in the sand layer. Therefore, the flood in Yangguan has harmed the three treasures: the reduction of water volume in major rivers breeds wetlands; Raise the groundwater level in the desert for afforestation and sand fixation; High-quality cold water filtered by sand layer can raise rainbow trout and irrigate agriculture and forestry.

Now, he and his colleagues are busy perfecting their own model of flood control and sand control, ready to promote it at home and abroad.

In the army-

Desert black tomato controls sand and poverty

When the sun sets on the flat sand, the stars on the dragon rise and fall. 1995, Chai Zaijun, a 33-year-old retired soldier, got to know Qian Xuesen's sand industry and engaged in agricultural production on barren land. This enabled Chai Zaijun to find a theoretical basis for turning sand into treasure, and he decided to devote himself to the cause of sand control.

Sand control is useless. Chai Jun has been thinking about how to engage in agricultural production on barren land, whether it is scarce for human body and whether it can be planted in ordinary fields. Chai Jun established Gansu Desert Ziguang Biotechnology Co., Ltd., relying on scientific and technological innovation, cultivated black tomato, an agricultural and forestry crop with extreme drought tolerance and extreme dry heat.

After 10 years of painstaking research and development, a standardized and large-scale production line for black tomatoes was built. Black tomato, black mulberry and blackcurrant are selected as qualified raw materials for Shenjiu and Shenshi space food.

Ten kilometers of windbreak and sand fixation forest belt is connected with nursery forest belt, and 30,200 mu of desert has become an oasis. Chai spent all his money on the army, and this career change brought him the most golden 20 years in his life. All kinds of honors witnessed his course of sand control, such as national green model workers, national outstanding retired veteran cadres, national outstanding private scientific and technological entrepreneurs, and outstanding socialist builders with national characteristics in Gansu Province.

At present, hundreds of thousands of farmers on the edge of the desert in Zhangye City have embarked on the road of agricultural industrialization, farmer industrialization and industrial standardization. The income per mu of land increased from 2300 yuan to 7600 yuan, and the water consumption decreased by 45%. It has embarked on a new path of combining sand control with poverty alleviation, ecological civilization and increasing farmers' income.

Altun Mountain is bordered by Kumutage Desert in the north and Qaidam Basin in the south. Located in the northwest desert, it belongs to the cold climate zone of Qinghai-Tibet Plateau. Although it is within the latitude of the warm temperate zone, it is located in the plateau mountainous area, with an average elevation of more than 3 kilometers. The influence of altitude on temperature has gone beyond latitude. It is characterized by drought and little rain, and the temperature difference between the four seasons is large. Winter is long and cold, and summer is short, windy and dry. Generally, it begins to snow and freeze in mid-September, and the snow and ice period lasts for 9 months.

English learning accumulates over time. It is located in a huge mountain range at the junction of northeastern Qinghai Province and western Gansu Province in China. It consists of many parallel mountains and wide valleys from northwest to southeast. Located in the south of Hexi Corridor, also known as Nanshan. The west end is at the mouth of Dangjinshan Mountain, connected with Altun Mountain, and the east end reaches the Yellow River Basin, with a total length of nearly 1000 km. The widest place is between Jiuquan and Qaidam basin, reaching 300 kilometers. From north to south, it includes Daxue Mountain, Tuolai Mountain, Tuolai Mountain, Maye Mountain, Shule Mountain, Danghe Mountain, Turgendaban Mountain, Qaidam Mountain and Zongwu Mountain. More than 4,000 peaks? Between 5000 meters, the highest peak-Tuanjie Peak at the southern foot of Shule Mountain is 5808 meters above sea level. The peaks above 4500 meters above sea level are covered with snow all year round, and the valleys above 3000 meters? Between 3500 meters. Qilian Mountain is located in the northeast of Qinghai Province, China, on the western border of Gansu Province. It consists of many parallel mountains and wide valleys from northwest to southeast. Located in the south of Hexi Corridor, also known as Nanshan. The western end is at Dangjinshankou, which is connected with Altun Mountain. East to the Yellow River Basin, connected with Qinling Mountains and Liupanshan Mountains. It is nearly 1000 km long. It belongs to folded fault block mountain. The widest place is between Jiuquan City and Qaidam Basin, reaching 300 kilometers. From north to south, it includes Daxue Mountain, Tuolai Mountain, Tuolai Mountain, Maye Mountain, Shule Mountain, Danghe Mountain, Turgendaban Mountain, Qaidam Mountain and Zongwu Mountain. The peak is 4000-5000 meters above sea level, and the highest peak, Unity Peak in Shule Nanshan, is 5808 meters above sea level. The peaks above 4000 meters above sea level are covered with snow all year round, and the valleys are also between 3000 and 3500 meters above sea level. The East Qilian Mountains decrease from west to east, including the corridor Nanshan-Lenglongling-Wushaoling, Datong Mountain-Dapo Mountain and Qinghai Nanshan-Labei Mountain. There are Datong River Basin, Huangshui River Basin and Qinghai Lake Basin. There are 3,306 glaciers, covering an area of 2,063 square kilometers. Qilian Mountain water system is radial: it radiates from Hala Lake to 99E. Form a large oasis in front of the mountain. There are cold temperate coniferous forests in the east, with an altitude of 2500~3300 meters. Forest resources have been severely damaged and wild animals have decreased. Qilian Mountain National Nature Reserve was established in 1987. Rich in mineral resources. In a narrow sense, Qilian Mountain refers to the northernmost corridor Nanshan and Lenglongling. The average altitude is over 4000 meters. The main peaks are Lenglongling (4,843m), Qilian Mountain (5,547m) and Shule Nanshan (5,808m). The water system of Qilian Mountain is in the form of radiation grid: it radiates from Hala Lake to the east through 99, and radiates to the surrounding low-lying areas. Also controlled by the northwest-southeast structure, the valley along this direction grows and spreads, and the valley that horizontally cuts the mountain becomes a canyon. Because the mountains in the north and east are high and rainy, the Datong River and Huangshui River in the east are rich in water, which can flow into the Yellow River and become outflow areas. Shiyang River, Heihe River, Shule River and Danghe River in the north also have a lot of water, forming a large oasis in front of the mountain. Oasis area gradually decreases from east to west. The southern foot of Qilian Mountain is relatively dry, based on Qaidam Basin, with small height difference and short rivers. There are cold temperate coniferous forests in the east of Qilian Mountain. The development degree decreases from east to west, but the distribution height increases, accounting for 2500 in the east. 3200 meters, 2700 in the middle? 3300 meters, and finally disappeared in the patches near the Beida River. Forests have been severely damaged, wild animals have decreased, and precious animals such as sable have become extinct. Jingtieshan Iron Mine, Mulihe Youxiang Coal Mine and Zongwu Longshan Metal Mine are rich in mineral resources and have important economic value. Geology: Qilian Mountain was originally a Paleozoic geosyncline, and a fold belt was formed after Caledonian movement and Variscan movement. Since Cretaceous, Qilian Mountain has been dominated by fault block movement, and finally formed a series of parallel horsts (or mountains) and grabens (valleys and basins). From north to south, there are eight ridges and valleys: Nanshan-Lenglongli Corridor.

Chaidamu Mountain-Zongwu Longshan-Qinghai Nanshan (Ku Beiling)-Laji Mountain and Chaka, and the basin-Yellow River Basin. These mountains in Shanxi are high in the north and low in the southeast. Most of them are 3,500-5,000 meters above sea level, and the highest peak is 5,827 meters in Shule Nanshan. The north and south wings of the mountain are extremely asymmetrical, with the relative height of 3000m on the north slope and only 500- 1000m on the south foot. Landform: Most of the low mountains are dry erosion, while the middle mountains are mainly water erosion, while the high mountains are mainly frozen weathering. Qilian Mountain has three levels of leveling: the first level is 4400~4600 meters above sea level in the east and 4800~5000 meters above sea level in the west; The second stage is 4000 ~ 4200m in the east and 4500 ~ 4700m in the west. The third stage is 3600 ~ 3800m in the east and 4000 ~ 4200m in the west. Multi-level terraces are developed in the central valley. The moraine landforms of ancient glaciers are widely distributed in areas over 2700~2800 meters on the northern slope. The lower limit of modern glaciers is 4 100-4300m on the north slope and 4300-4500m on the south slope, and the west is 200-300m higher than the east. Glaciers have been retreating in the past 100 years. There are 3066 glaciers in Qilian Mountain, with a total area of 2062.72 square kilometers. The water storage capacity is 654.38+32 million cubic meters. Among them, Nanshan Corridor, Shule Nanshan and Danghe Mountain have the most glaciers, while Shule Nanshan, Daban in Torkan and Nanshan Corridor have the most glaciers. Terrain: The mountainous area is 400 kilometers wide and is a mountain system composed of more than 7 mountains. There are lakes and valleys, such as Shule River, Danghe River, Heihe River, Datong River, Hala Lake and Qinghai Lake. The peak is more than 4000 meters above sea level, and the highest peak, Unity Peak in Shule Nanshan, is 6305 meters above sea level. The north and south sides of Qilian Mountain respectively descend to the plain with obvious faults. The relative height between the northern slope and Hexi Corridor is over 2000 meters, while the relative height between the southern slope and Qaidam Basin is only over 1000 meters. Qilian Mountain in a narrow sense only refers to the northernmost column. It is the watershed between the Yellow River and interior drainage. The mountains are high and the valleys are wide, accounting for more than one third of the total area of the mountains. This is a pasture rich in aquatic plants. The low-lying Datong Valley and Huangshui Valley are important agricultural areas in Qinghai Province. There are many snow-capped peaks and glaciers in Qilian Mountain. Although the scale of the glacier is not large, the river can go straight down to the arid area of the corridor because of the high mountain water. Therefore, melting ice and increasing ice water are necessary measures to develop agriculture in local mountainous areas. As early as the late Qing Dynasty, people had already gone up the mountain to melt ice and water. According to the statistics of 1962, there are 16 19 glaciers in Qilian Mountain, with an area of about 13 16 square kilometers. Most of them belong to continental glaciers with small moraine surface and slow movement. However, in terms of water storage capacity, it is not small. For example, Qiyi Glacier in Qilian is about 30.5 kilometers long and 80 meters thick, with a storage capacity of 65.438+0.5 billion cubic meters. The total annual rainfall in Qilian area is about 50 billion cubic meters, and the outflow is only 654.38+0.5 billion cubic meters. Therefore, the melting of ice and snow can increase the amount of water, which is an important water source for local agricultural development. In addition, Qilian Mountain is rich in forest and mineral resources. Water system: Qilian Mountain water system is distributed in a radial network. The radiation center is located near 3820 north latitude and 99 east longitude, which is the source of the so-called five rivers, that is, the source of Tolai River (Beida River) and Buha River. From here, along the line to Mao Mao Mountain, along Datong Mountain, to the eastern part of Nanshan Mountain in Qinghai, it is the dividing line between the inner and outer basins. The tributaries of the Yellow River on the southeast side of this line are Zhuanglang River and Datong River, which are outflow water systems. In northwest China, Heihe River, Tolai River, Shule River and Danghe River belong to the internal water system of Hexi Corridor. Harten River, Youxiang River, Tataleng River and Alanggole River belong to the internal water system of Qaidam Basin. Hala Lake also has two independent internal drainage systems. thorium

The east of the mountain is wet, while the west is dry. Vegetation: the vertical belt structure of vegetation on the north and south slopes of East and West Mountains is different. Vertical belt spectrum of vegetation in Dongpo (from bottom to top): desert belt (only grassland desert sub-belt)-mountain grassland belt-mountain forest grassland belt-alpine shrub meadow belt-alpine sub-snow sparse vegetation belt. South slope: grassland belt-mountain forest grassland belt-alpine shrub meadow belt-alpine sub-snow sparse vegetation belt. Northwest slope: desert belt-mountain grassland belt-alpine grassland belt-subalpine snow sparse vegetation belt. South slope: desert belt-alpine grassland belt (limited to desert grassland sub-belt)-alpine sub-snow sparse vegetation belt. Corresponding to soil vegetation is the northern slope of the eastern section: calcareous soil belt-mountain chestnut soil belt-mountain black soil (sunny slope) and mountain forest gray cinnamon soil belt-alpine meadow soil (sunny slope) and alpine shrub meadow soil (shady slope)-alpine desert soil belt. South slope: calcareous soil belt-mountain chestnut soil (sunny slope) and mountain forest gray cinnamon soil (shady slope)-alpine meadow soil (sunny slope) and alpine shrub meadow soil (shady slope)-alpine desert soil belt. Northwest slope: brown desert soil belt-mountain calcareous soil belt-mountain chestnut soil belt-mountain desert soil belt; South slope: gray-brown desert soil belt-alpine brown calcareous soil belt-alpine cold desert soil belt. Economy: Agriculture in Qilian Mountains is mainly limited to the Huangshui River, the middle and lower reaches of Datong River and the hilly area on the northern slope in the east. Spring wheat, highland barley, potatoes, rape, peas and melons are harvested once a year. The vast grassland is suitable for the development of animal husbandry, and there is a large area of water conservation forest. There are many medicinal and other economic plants and many precious animals, such as Gansu red deer, blue pheasant, blood pheasant and forest musk deer. There are siderite-specularite and hematite-magnetite in the north of Qilian Mountain. There are pyrite-type copper deposits in East Qilian Mountains. There are wolframite chronological veins and tungsten-molybdenum deposits in the northern and southern mountains of Jiuquan, which is one of the regions rich in tungsten resources in western China. Qilian Mountain Nature Reserve is located at the junction of Gansu Province and Qinghai Province, covering an area of more than 230,000 hectares. 1988 has been designated as a national nature reserve.

4. Altun position

gold mine

The copper mining area is located on the northern slope of Altun Mountain, belonging to the alpine region. The terrain is undulating and the cutting force is strong. At an altitude of 4730-5560 meters, the region has a typical continental alpine climate with changeable weather. May-July is the rainy season every year, and rain, snow, hail and other weather are often encountered. Leng Xia is cool in winter, with the highest temperature 18, the lowest temperature -40, and the annual average temperature of 0. Monsoon power is not strong all year round. Every year 165438+ 10 to March of the following year, the mountain is closed due to heavy snow. The water system is developed, and it is covered by grassland along the water system, which is a summer pasture for Uygur herders to graze. Due to the high altitude and lack of oxygen, the staff have different degrees of altitude sickness and strong ultraviolet radiation.

5. Which city is Altun in?

The unrecognized ethnic groups in China refer to those who have been assimilated into the Han nationality or other ethnic groups by People's Republic of China (PRC) (PRC) but have not been officially recognized, or those who have not been officially recognized because of unclear ethnic discrimination. According to the sixth national census on 20 10, the unidentified population of ethnic minorities in People's Republic of China (PRC) is 640 10 1. The unidentified ethnic groups in China are mainly distributed in the southwest, with the largest number in Guizhou Province, followed by Yunnan Province and Xizang Autonomous Region. In addition, there are more than 1000 unidentified ethnic groups in Zhejiang, Guangdong, Guangxi and Jiangsu provinces.

6. Xinjiang Altun

The smallest in great basin is the Qaidam Basin.

1. Tarim, the largest inland basin in China. In the south of Xinjiang Uygur Autonomous Region. North, west and south are surrounded by Tianshan Mountain, Pamir Plateau, Kunlun Mountain and Altun Mountain. Overall, it is rhombic, with an altitude of about 1 1,000m, above 1 1,000m in the west and 780m in Lop Nur in the east. It covers an area of 530,000 square kilometers.

2. Junggar Basin is the second great basin in China, with an area of about 380,000 square kilometers. It is located between Altai Mountain and Tianshan Mountain, and its outline is an unequal triangle: Sawur, Talbahatai, Baluchistan, Alashan and other low mountains in the west, and Beita Mountain in the north; There are several low-lying gaps in the west, and humid air from the Atlantic Ocean can enter the basin, so it is called a semi-closed inland basin.

3. Sichuan Basin, one of the four great basin in China, is dominated by shallow hills and plains, with an area of 6,543,800+0.65 million square kilometers. The elevation in the basin is 200 ~ 750m, and it inclines from north to south.

4. The Qaidam Basin is bounded by Qilian Mountain in the northeast, Kunlun Mountain in the south and Altun Mountain in the northwest, with an area of1.2000 square kilometers.

7. Albanians

The dividing line between the first step and the second step is Kunlun Mountain-Qilian Mountain Rift-Hengduan Mountain, which is the dividing line between the first step and the second step. It is also the dividing line between Kunlun Mountain-Altun Mountain-Qilian Mountain Rift-Hengduan Mountain Altun Mountain.
