administrative division

Dazhou City was renamed from the original Dachuan area with the approval of the State Council in 1999. Now it has jurisdiction over Tongchuan District, Daxian County, Xuanhan County, Kaijiang County, Dazhu County and Quxian County, and Wanyuan City. The whole area is 1.66 million square kilometers, which belongs to subtropical monsoon climate and has a magnificent terrain. As early as the "Sichuan-Shaanxi Revolutionary Base" period, the people of Dazhou made selfless contributions to the China Revolution, and the touching stories left by the proletarian revolutionaries of the older generation, such as Xu, Li Xiannian and others, have been widely celebrated so far. After the founding of New China, the people in the old areas carried forward the spirit of the Red Army and worked hard, which made Dachuan area with a glorious history form its own economic advantages and unique cultural customs. [Edit this paragraph] Traffic Dazhou has convenient transportation and active business. Dazhou is the eastern passage from Tongjiang to Dahai in Sichuan, and it is the transportation hub at the junction of Sichuan, Chongqing, Hubei and Shaanxi. National highways 2 10 and 3 18 run through the country. Dayu Expressway goes directly to Chongqing, and Dashan Expressway has started construction. After the completion of the whole line, you can run a round trip from Dazhou to Xi 'an in one day, while it only takes about 9 hours from Chengdu to Xi 'an via Dazhou. Dawan Expressway is scheduled to start at the end of 2008 and be completed and opened to traffic by the end of 201/kloc-0. Dazhou Heshi Airport has direct flights to Chengdu, Guangzhou, Beijing and other places. Dazhou is the eastern passage from Tongjiang to Dahai in Sichuan, and it is the transportation hub at the junction of Sichuan, Chongqing, Hubei and Shaanxi. Qujiang shipping goes directly to Chongqing. * * * There are nine navigable rivers, including Qujiang, Bahe, Zhouhe and He Qian, Houhe, Zhonghe, Tiexi, Qingxi and Lingang River, which basically form a waterway transportation network with Qujiang, Zhouhe and Bahe as the main streams, covering four counties (cities) in the city. Dazhou railway network is very developed. Dazhou Railway Station has trains to Chongqing, Chengdu, Wanzhou, Guiyang, Xi 'an, Beijing West, Hankou, Zhengzhou, Fuzhou, Guangzhou and other places, providing services such as passenger transport, ticket sales, luggage and logistics. The station always takes reputation first, customer first and quality service as its business purpose, and serves every customer wholeheartedly. Dazhou Railway Station is the fourth largest railway station and the second largest marshalling station in southwest China. [Edit this paragraph] Dazhou Topography Dazhou is high in the northeast (Daba Mountain area) and low in the southwest (basin hilly area). The highest point is Datuanbao, Jichang Township, Xuanhan County, with an altitude of 2,458.3 meters; The lowest place is Tianguan Village, Wang Xi Township, Quxian County, with an altitude of 222 meters. Daba Mountain lies in the north of Xuanhan, and Mingyue Mountain, Tongluo Mountain and Huafu Mountain run through the north and south, dividing the city into three parts: mountainous area, hilly area and flat dam. Mountain area accounts for 70.70%, hills account for 28. 10%, and flat dams account for 1.20%. The northern mountainous area is severely cut and steep, forming a landform unit of middle and low mountains; The south-central part is relatively flat, forming an equi-valley landform unit. [Edit this paragraph] Daba Mountain in Dazhou Mountain Area

The watershed between Jialing River and Hanjiang River, and the geographical dividing line between Sichuan Basin and Hanzhong Basin. In a narrow sense, Daba Mountain only refers to Micang Mountain and Daba Mountain in the border areas of Sichuan, Shaanxi and Hubei provinces. It stretches for more than 500 kilometers from east to west, so it is called Li Qian. Bashan for short. Daba Mountain in a broad sense is the general name of the mountainous areas at the junction of Sichuan, Gansu, Shaanxi and Hubei provinces, including Motianling in the west of Micang Mountain and Shennongjia in the east of Daba Mountain. Daba Mountain lies between the Qinling geosyncline in the north and the Sichuan platform syncline in the south. Because of the control of the north-south tectonic line, the mountain presents a series of regular parallel fold belts composed of anticlines and synclines, but the east and west are slightly north and the middle is slightly south, so it is called Dabashan arc fold belt. The strata are ancient, mainly limestone, dolomite, metamorphic rocks and sandstone, with granite distributed locally. The first two karst landforms, such as multi-peak cluster, karst cave and underground river, are famous as Guangyuan Longdong Cave, Wangcang Huang Yang Cave and Tongjiang Zhongfeng Cave. The ridge is composed of hard crystalline limestone, which is magnificent after rising and denudation. It is about 2000 meters above sea level, 2797 meters away from Wuxi Taiping Mountain and 3 105.4 meters away from Hubei Shennongjia, which is the highest.

Huayingshan

Huaying Mountain, which originated at the southern foot of Daba Mountain, is the boundary mountain between parallel folded ridges and valleys in eastern Sichuan and hills in central Sichuan. From northeast to southwest, it spans Dazhou, Guang 'an, Chongqing, Neijiang, Zigong, Luzhou and Yibin, with a total length of 325 kilometers. Huaying Mountain is named after "the snow on the top of the mountain looks like Qiong Yao spreading the ground and Jing Yu spreading the mountain". Huaying Mountain enters the northeast of Guang 'an District from the south of Quxian County, reaches Baoding at the junction of Linshui County and Huaying City in the south, and extends to Yubei District and Hechuan City in Chongqing. Huaying Mountain is about 70 kilometers long in Guang 'an, generally 6 kilometers wide and 9 kilometers wide at its widest point. From Linshui Temple Liangzi to Baoding, it is the highest part of Huaying Mountain, with an altitude of1704m, and it is also the highest peak in Sichuan Basin. Huaying Mountain is rich in mineral resources, dense forests and a wide variety of animals, and its natural and cultural landscape is of great tourism development value. 1993, Huaying Mountain was listed as a provincial-level scenic spot.

Tongluoshan

Tongluo Mountain is the second mountain range in the parallel folded valley area in eastern Sichuan. It starts at the northern end of Pushan Mountain in Lei Yin, Daxian County, and runs northeast to southwest, passing through Dazhou, Dazhu County, Linshui County, Changshou County, Yubei District, Nan 'an District, Banan District, Qijiang County and other counties in Chongqing, and ends at Tiantai Mountain on the north bank of Qijiang River. The total length is 260 kilometers, the width is 5 kilometers-10 kilometers, and the general elevation is 600 meters-1000 meters. The highest peak is Feng Wan Mountain in Longan Town, Linshui County, with an altitude of1054m. Because the Yangtze River passes through the mountains to the east of Chongqing, Tongluo Gorge is formed, and the river in the gorge hits the stone like the sound of Tongluo, hence the name Tongluo Mountain. Tongluo Mountain enters Linshui County from Daancao in Dazhu County, passing through Xinzhen, Taihe, Lengjia, Chang 'an, Liangban, Jiu Feng, Yao Feng and Tan Yao. It is about 65 kilometers long, including a section from Feng Wan Mountain to Xianying Mountain. The mountains are steep and the valleys are deep. It is the highest terrain in Tongluo Mountain. The axis of anticline has been eroded for a long time, showing the shape of "one mountain, two ridges and one trough". There are many residual hills, karst depressions and sinkholes in the trough, which has a typical karst landscape. The valleys such as Daping, Guiren trough, beam slab and Changjiacao are flat and open, with dense population, fertile land and rich products. On both sides of the valley, there are caves everywhere, especially in the area from Jiu Feng to the Little Three Gorges of Yulin River. There are more than 30 caves, among which Jiulong Cave, Moon Cave, Lanjiadong, Hejiadong, Lion Cave and Xianren Cave have the best scenery. There are 7 hot springs in Xiaonanhai area of the Three Gorges of Yulin River, which are rich in trace elements beneficial to human body. Tongluoshan has 10 kinds of mineral resources, such as coal, iron, limestone, silica, gypsum, dolomite, quartz sand, natural gas, mineral water, lithium and beryllium. The mountains are almost covered by dense forests, and thousands of peaks are covered with green, covering the sky. It is rich in Pinus massoniana, Chinese fir and cypress, and is an important timber forest base in Linshui County.

Mingyue Mountain is the third mountain range in the parallel folded valley in eastern Sichuan. It starts from Kaijiang County in the north and moves from northeast to southwest. It passes through Dazhou, Liangping, Dazhu, Linshui, Dianjiang, Changshou, Yubei and other counties, and ends at Yongxing Field in Banan District. The total length is 232 kilometers, the width is 4 kilometers to 6 kilometers, and the general altitude is 700 meters to 1000 meters. Because the Yangtze River crosses the mountains between Yubei District and Banan District, it forms a canyon. There is a round hole like a full moon on the cliff on the bank of the canyon, so it is called Yueming Gorge Valley, and this mountain is named after the canyon.

Moon Mountain

Mingyue Mountain enters Linshui County at Xiayan Cang in Dazhu County, and is the watershed of Dahong River between Dianjiang County, Changshou County and Linshui County. It passes through Hulin, Xingren, Lion, Baer, Fenghe, Lijia and other towns, with a length of about 47 kilometers. From Yaguai Mountain, a neighboring township, to Zhongchengzhai, a lion township, there are towering peaks, steep cliffs, deep streams and splashing springs. Its highest peak is Xingren Tuya, with an altitude of 1 179 meters, which is the third peak of Mingyue Mountain. From Zhongchengzhai to Xinglong Bay, the slope is gentle, the top of the mountain is round, there is no obvious sudden peak, and the relative height difference is not big. The mountain is "one mountain with two ridges and one trough", but the trough Gu Duo is in Dianjiang and Changshou counties, only in Lijia's Jiangjiacao and Dabangou. Mingyue Mountain is rich in coal, meteorology, gypsum and other mineral resources. It is the largest timber forest base in Linshui County and plays a good role in water conservation of Dahong River. Forest vegetation is dominated by plantations such as Pinus massoniana and Chinese fir. Relict plant Alsophila spinulosa is distributed in the deep valleys around Yangchagou, Daoxugou and Longwanggou. This ancient plant was on the verge of extinction during the Quaternary Glacier, but now it is rare in the world, so it is called "living fossil", which has great scientific research value and tourism development value. [Edit this paragraph] Dazhou Hydrology The rivers in Dazhou mainly belong to the Jialing River system, a tributary of the Yangtze River, which originates from Daba Mountain and is distributed in a dendritic shape from north to south. Heqian River, Zhonghe River and Houhe River join Zhouhe River in Sanhui Town, Quxian County, and then join Bahe River in Qujiang River, and flow southward for 300 kilometers to join the Yangtze River. There are 53 rivers with a drainage area exceeding 1000 square kilometers, and there are 15 major rivers with a drainage area exceeding1000 square kilometers. * * * There are nine navigable rivers, including Qujiang, Zhouhe, Bahe, He Qian, Houhe, Zhonghe, Tiexi, Qingxi and Lingang rivers, which basically form a waterway transportation network with Qujiang, Zhouhe and Bahe as the main streams, covering four counties (cities) in the city. The navigation mileage of each river is different, and the capacity is below100t.

Qujiang

Qujiang River belongs to Jialing River system. There are many tributaries of Jialing River, and the largest two are Fujiang and Qujiang. Qujiang originates from Daba Mountain, also known as diving, and flows through Bazhong and Dazhou until Sanhui Town in Quxian County, which is called Qujiang, with a total length of 720 kilometers. Fujiang River originates from Xuebaoding, Minshan Mountain, and flows through Mianyang, Deyang, Suining, Guang 'an and other hilly areas in central Sichuan, with a total length of 700 kilometers. Both rivers meet Jialing River in Hechuan. Qujiang River starts in Sanhui Town, Quxian County, and flows from north to south in Quxian County. It flows through eight towns, including Sanhui District, Tuxi District, Linba District, Suburb, Qujiang Town, Xiandu District and Langya District, with 2/kloc-0 towns, among which it flows into tributaries such as Yongxing River, Guixi River, Liujiang River and Zhongtan River. Leave the country from Wajiao Beach in Langya Township at the southernmost tip of Quxian County, enter Qinlao Village in Xiaoxi Township of Guang 'an County, obliquely cross the central part of Guang 'an County from northeast to southwest, flow through Hengsheng District, Stalagmite District, Guange District, Daicheng District, Kwun Tong District, Xiexing District, Guangfu District and Huaying City, and enter Zhonghe District and Luodu District of Yuechi County from Laojun Village in Hualong Township of Guangfu District. It asked about Linxi River, Luodu River, Xinmin River and Qujiang River which originated from Huaying Mountain. They left the country at Danxikou, Shunliangzhai Village, Sailong Township, Yuechi County, entered the northeast of Hechuan County, and passed through incense burners, docks, mosquito dragons, ancient cities, Sun Jia, Weixi, Shuanghuai and Laimen in five districts of Weixi, Longshi, Xiaomian, Guandu and Yunmen.

Tongchuan bridge

Hanyu Highway is the shortest route to transport Soviet aid anti-Japanese materials to Chongqing, which was then called "Chuanshan East Road". It is more than 90 kilometers shorter than Chuanshan Middle Road and 270 kilometers shorter than Chuanshan Road. Therefore, the Wuhan National Government ordered the construction in February 1938. Ding Gongnan arrived at Hanyu Highway in August of that year, and successively served as the captain of the second survey team and the chief of the second works section, responsible for the layout and construction of the northern section of Daxian County. 1June, 940, due to the reduction of Soviet aid to China, the Han (middle) Xuan (Han) section was ordered to stop work, and the original Hanxuan and two engineering offices were reorganized into Hanyu Highway Engineering Office, with Ding Gongnan as the general engineering office, responsible for the survey and installation of the 4 17 km highway from Wanyuan to Chongqing. Among them, the terrain north of Daxian County is complex, the project is arduous, and the route selection is very difficult. However, the organization, personnel and funds of Hanyu Road are excellent, and the technical standards are strict, which increases the arduousness of survey and route selection. With the joint efforts of him and the vast number of technicians, Hanyu Highway became a highway with good alignment standards at that time and was well received. There are many bridges and culverts in this road, and most of them adopt stone arches and reinforced concrete permanent structures. Therefore, at that time, the bridges and ferries with spans exceeding 10 meters were identified, and the Bridge Crossing Engineering Office was established to take charge. But 194 1 Tongchuan Bridge, which was completed at the beginning of the year, was assigned by Ding Gongnan when he was the captain of the second survey team. This bridge is located near the county seat of Daxian County, across the state river. Zhouhe River is formed by the confluence of River, Middle River and Houhe River. During the flood season, flash floods broke out and the water flowed rapidly. After repeated investigation, he chose the bridge site at that time. The current is straight and the foundation is good. After passing through the Bridge Crossing Engineering Department, the bridge is designed as a reinforced concrete cantilever beam bridge with a span of 20 meters, 1 1 hole. Together with the approach bridge, the length of the whole bridge is 300.94m, and the design load is15t. It was a permanent highway bridge with the largest span and cantilever structure at that time. There are archways at the north and south ends of the bridge, and the three characters "Tongchuan Bridge" inscribed by Zhang Jiaao, Minister of Communications of Chongqing National Government, and Zhao Zukang, Director of the General Administration of Highways are engraved on the horizontal forehead. On the archway at the southern end, there is also a couplet inscribed by Zhou, a famous highway expert who was then the deputy director of the Office of the General Administration of Highways: "Stack stones to start Changhong, enjoy this day, and * * * wish Tongchuan victory; Helping people board the other shore is willing to unite the whole people in the future and complete the great cause of founding the country. " Bearing in mind the grand occasion of the completion of the new bridge, express the wish of uniting and building the motherland. All this shows that the completion of this bridge has made great contributions to supporting the anti-Japanese war.
