Genetic types of tectonic lakes

Summarize the English name of Tianchi. Also known as Tianchi or Dianchi Lake, also known as Kunming Lake and Kunming Pool. The Great Lakes in Yunnan Province, China. In the southwest of Kunming, together with Xishan Mountain on the west side of West Lake, it is a famous tourist resort. Formed by structural collapse. There are rivers such as Panlong River. Lake elevation 1, 886 meters, covering an area of 330 square kilometers. The average water depth is 5 meters and the deepest is 8 meters. The lake is discharged from the southwest of Haikou and named Tanglangchuan, which is the source of Pudu River, a tributary of Jinsha River. In the past, floods often occurred around this lake. As early as 1262, Songhua River Dam was built on Panlong River, and Haikou River was dug in 1268 to increase the outflow of Dianchi Lake and reduce the flood disaster around the lake. 1955, more than ten large and medium-sized reservoirs were built on the river upstream of the lake, and dozens of electric irrigation and drainage stations were built along the lake to alleviate the flood disaster and ensure farmland irrigation and urban industrial and domestic water use. Carp, crucian carp and money fish are produced in the lake.

Ecological characteristics

Dianchi Lake is a eutrophic lake, and some lakes show signs of abnormal nutrition, and the water color is dark yellow-green. The organic pollution in the inner lake is serious and harmful, and the pollution develops rapidly. Some water bodies in the outer lake have been polluted by organic matter, and toxic and harmful pollution (mainly heavy metal pollution) is not prominent. Nitrogen, phosphorus, heavy metals and arsenic are deposited at the bottom of the lake, causing serious sediment pollution. Dianchi Lake has been in the state of "aging" lake for nearly a hundred years. The annual average water temperature is 65438 06℃; In the 1980s, no survey results showed that with the changes of the ecological environment in Dianchi Lake, the destruction of the ecological environment of fish spawning and hatching sites, and the influence of overfishing and the interaction between fish populations, the fish population in Dianchi Lake has undergone tremendous changes, leaving only four indigenous species, which are on the verge of extinction. For example, golden thread fish, fresh and delicious, is now extinct, an alien species.

Morphological description Dianchi Lake is distributed in the north-south direction. The lake is slightly arched, with the arch back facing east. There is a natural sand dike in the northeast, which is 4 kilometers long and divides Dianchi Lake into two parts: the outer lake and the inner lake. It is1887.5m above sea level, with a total area of 311.338km2, of which the inner lake area is10.67km2, the outer lake area is 287. 1 km2, and the lake length is 4 1.2. The sediment in the inner lake is fat, the silt is thick, there are animal and plant residues, it is black and smelly, and the outer lake is fat, brown and has skeleton mud; The upstream rivers mainly include Panlong River, Baoxiang River, Xinhe River, Liangyun River, Mario River, Daqing River, Luolong River, Laoyu River and Wangliang River. ...

Dianchi Lake is located at the foot of Xishan Mountain in the south of Kunming. Its northern end is adjacent to Kunming Daguan Park, and its southern end is in Jinning County, 5 kilometers away from the urban area. Historically, it has always been a resort for vacation and summer vacation. Dianchi Lake was called Nanze in ancient times, also known as Kunming Lake, about 20 kilometers away from Kunming. More than 20 rivers, such as Panlongjiang River, flow into Dianchi Lake, and the lake flows out to the sea in the west, and enters Jinsha River through Pudu River. It is shaped like a crescent moon, 39 kilometers long from north to south and 13.5 kilometers wide from east to west, with an average width of about 8 kilometers. The lakeshore line is about 200 kilometers long; The lake covers an area of 300 square kilometers, ranking first in Yunnan Province. The maximum depth of the lake is 8 meters, the average depth is 5 meters, and the water storage capacity is 65.438+0.57 billion cubic meters, which is known as the "Five Hundred Miles Dianchi Lake". It is the sixth largest inland freshwater lake in China.

Dianchi Lake is a plateau limestone rift lake formed by the crustal movement of the tertiary Himalayan mountains, with an altitude of 1.886 meters. There are dozens of peaks around Dianchi Lake, which are surrounded by mountains and waters, and the sky is misty, forming a beautiful natural picture.

Dianchi Lake has magnificent scenery and vast water surface. Standing on the Longmen, commanding, Dianchi Lake has a panoramic view and is known as the "Pearl of the Plateau". Its charm lies in its endless changes with the changes of the sky, sun and clouds in one day. Dianchi Lake has a vast water surface, which is not only a good place for tourism, but also has great economic value, such as shipping, fishing, irrigation and water supply. There are many scenic spots around Dianchi Lake, facing Xishan Forest Park and Daguan Park across the water. Yunnan ethnic village, ethnic sports training base and Yunnan ethnic museum are interrelated and relatively independent, relying on each other, which is an ideal place for sightseeing, entertainment and vacation. 1988, Dianchi Lake was approved by the State Council as the second batch of national scenic spots in the name of Kunming Dianchi Lake Scenic Spot.

The origin of the name of Dianchi Lake can be summarized into three statements. 1. Geographically, Chang Qu, a native of A Jin, said in "Huayang Guozhi Nanzhong Zhi": "Dianchi County is governed by the county, so the country of Yunnan is also; There is a river, which is 200 miles around the water, deep and wide, and the downstream is shallow and narrow, such as countercurrent, so it is called Dianchi Lake. " Another way of saying this is to find the sound and try the meaning, and think that "the canon is also the top of words." Others think it is Yidie (Dian), that is, Dabazi. The third way of saying this is from the perspective of national appellation. According to Historical Records Biography of Southwest Yi, "Dian" was the largest tribal name in this area in ancient times. After General Chu entered Yunnan, he changed his clothes, commonly known as Wang Dian, so there was the Dianchi tribe, and the name of Dianchi Lake came from this.

Dianchi Lake, surrounded by mountains, rivers and fertile land, is called "the south of the plateau". Around the pool, there are fishing villages and Guanyin Mountain scenic spots dotted with sails; Baiyukou Lake is an empty valley garden with flowers and trees; There are miles of clear water, lakeside baths on the ridge and beautiful Daguanlou Park. These are very pleasant places, especially on the other side of the Green Wave, at the top of the majestic Western Hills, covered with water and clouds. The beauty of the lake and the mysterious scenery like the sea will appear in front of your eyes. Dianchi Lake has both the beauty of the lake and the boldness of the sea.

Dianchi Lake is one of the first batch of 12 national tourist resorts approved by China, and it is also the only national resort located in inland provinces. Ridge Park is near Dianchi Lake, and the whole park is built along the shore of Dianchi Lake. Weeping willows, green lychees and bailangtan are ideal natural swimming pools in southern Xinjiang with colorful scenery. In the park, overlooking the Xishan Forest Park on the high mountain opposite the lake is even more pleasing to the eye. If you want to visit the Western Hills, fishing boats driven by fishermen can cross the water to reach the foot of the Western Hills on the pier of the park dam. You can also take a cable car to Xishan in the ethnic village of Haigeng, overlooking Dianchi Lake from the cable car, with a panoramic view of thousands of waves, lakes and mountains.

Dianchi Lake is also the center of scenic spots in Kunming. Visitors can not only take a boat tour around the lake and enjoy the beautiful scenery, but also go ashore to visit Zheng He's hometown, Guanyin Mountain and other scenic spots.

Pollution in Dianchi Lake is a worrying topic. Since the Seventh Five-Year Plan, China and Yunnan Province have invested more than 4 billion yuan to control the pollution in Dianchi Lake. Although these funds from the central and local governments and loans from the World Bank have effectively alleviated the deterioration of the ecological environment in Dianchi Lake, they have not completely eradicated the pollution in Dianchi Lake. At present, it still belongs to five kinds of heavily polluted lakes.

In recent years, Dianchi Lake has been seriously polluted and listed as one of the "three lakes and three rivers" by the State Council. The pollution in Dianchi Lake has gone through a long and complicated process. Water pollution began in the late 1970s, and in the 1980s, especially in the 1990s, eutrophication became increasingly serious. The causes of water pollution in Dianchi Lake are as follows: First, Dianchi Lake is located in the lower reaches of Kunming City, which is the lowest depression in Dianchi Lake Basin; Second, domestic sewage enters Dianchi Lake; Third, industrial wastewater enters Dianchi Lake; Fourth, agricultural non-point source pollution; Fifth, the rapid development of urbanization in Dianchi Lake Basin; Sixth, Dianchi Lake is a semi-closed lake, and there is not enough clear water to replace the lake. Seventh, in the process of natural evolution, the lake surface shrinks, the lake basin becomes shallow, and it enters the aging stage, and endogenous pollutants accumulate and the pollution is serious.

Transportation: Visitors from the railway station to Dianchi Lake can take bus No.24 and No.44 and get off at Haigeng Park. Ticket price 1 yuan.

Admission: free.

Haigeng Park: 8 yuan

It seems that the ticket has become more expensive, and it costs money to take a bus.

[Edit this paragraph] Create a "plateau water town" near Dianchi Lake.

Kunming will build the peninsula with Fu Bao Eco-cultural City as the core and Dianchi Lake as the backing into a "highland water town". The day before yesterday, the Controlled Detailed Planning of Peninsula Zoning in the Main City of Kunming, which was just compiled by Guandu District Government and Provincial Urban and Rural Planning and Design Institute, was exhibited in Kunming Planning and Exhibition Hall, and was publicized from yesterday, with a publicity period of 15 days.

Peninsula base area is located on the north bank of Dianchi Lake, which is the wetland restoration area of Dianchi Lake. Located in the ecologically sensitive land-water intersection zone, it has a unique and good natural ecological foundation. The planned control area here covers an area of about 8 square kilometers, surrounded by water on three sides and has a long coastline, which is likely to be biodiversity. Its construction is not only related to the development of villages and Liu Jia Township in the peninsula area, but also to the future of the peninsula in the peninsula area. More importantly, it is related to the overall situation of the entire Dianchi Lake water area and the sustainable development of Dianchi Lake ecology.

Therefore, in the detailed rules, relevant experts suggested that the South Road and the North Road should be developed in different regions. Among them, Huanhu East Road divides the peninsula into north and south parts. The construction conditions in the two regions are different and each has its own advantages.

One is the area north of Huanhu Road. There are Liu Jia Town Government and many villages in the north of this area, which undertake the urban development of Kunming to the north. Because there are many township enterprises in Liu Jia, and the printing and other cultural industries are the main industries, there is no centralized cultural industry gathering place in Kunming at present. Therefore, combined with the overall planning of Kunming, the function of Lubei Development Zone is to develop cultural industries and form a gathering area of printing, publishing, audio-visual products and other industries, including production and logistics. At the same time, this area also has high-grade residential areas and commercial functions that match the industrial area.

South of Huanhu Road, in addition to some original natural villages, there are some leisure and entertainment projects represented by Fu Bao Cultural City, and educational projects such as Kunming Art College. The area is surrounded by water on three sides and has a good natural landscape foundation. Therefore, the planning combines the comprehensive consideration of Dianchi Lake landscape construction, wetland restoration and tourism development, and determines that the area is mainly based on eco-tourism construction, wetland ecological restoration and artistic and cultural industry development. Among them, the south of Huanhu East Road is dominated by ecological construction, which combines wetland restoration and water system extension. The free and loose structure mode will be adopted, so that the existing green space will always run through it, and the wetland will also move inland with the water system. Appropriate eco-community and eco-tourism construction will be carried out in this area, so as to protect and utilize the ecological landscape of the peninsula.

It is also pointed out in the detailed rules that it is important to protect and restore the local wetland system and maintain the balance of the ecological environment in Dianchi Lake in order to truly build a "highland water town".
