Administrative divisions

Dazhou City was renamed and established from the original Dachuan District with the approval of the State Council in 1999. It currently governs four counties: Tongchuan District, Daxian, Xuanhan, Kaijiang, Dazhu, and Qu counties, as well as Wanyuan City. The whole district covers an area of ??16,600 square kilometers. The whole district has a subtropical monsoon climate and majestic and winding terrain. The people of Dazhou have made selfless contributions to the Chinese revolution as early as the "Sichuan-Shaanxi Revolutionary Base" period. The moving deeds left by the older generation of proletarian revolutionaries such as Xu Xiangqian, Li Xiannian, and Wang Weizhou on this red land are still remembered by everyone. . After the founding of the People's Republic of China, the people of the old areas carried forward the spirit of the Red Army and worked hard to start their own business, which enabled the Dachuan area with a glorious history to form its own economic advantages and unique cultural customs. [Edit this paragraph] Transportation Dazhou has convenient transportation and active commerce. Dazhou is the eastern channel connecting the river and the sea in Sichuan and the transportation hub at the junction of Sichuan, Chongqing, Hubei and Shaanxi. National Highways 210 and 318 run across the entire territory. The Da-Yu Expressway leads directly to Chongqing, and the construction of the Da-Shaan Expressway has begun. After the completion of the entire road, it will be possible to run back and forth from Dazhou to Xi'an in one day, while it will take about 9 hours to travel from Chengdu to Xi'an via Dazhou. The Dawan Expressway is scheduled to start construction at the end of 2008 and be completed and open to traffic by the end of 2011. Dazhou Heshi Airport has direct connections to Chengdu, Guangzhou, Beijing and other places. Dazhou is the eastern channel connecting the river and the sea in Sichuan and the transportation hub at the junction of Sichuan, Chongqing, Hubei and Shaanxi. Qujiang Shipping leads directly to Chongqing. There are 9 navigable rivers in the country, namely Qujiang, Bahe, Zhouhe, Qianhe, Houhe, Zhonghe, Tiexihe, Qingxihe, and Linggangxi. Basically, they are composed of Qujiang, Zhouhe, and Bahe. The waterway transportation network of the main stream of the river covers the four counties (cities) of the city. Dazhou's 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, and provides passenger transportation, ticketing, luggage, logistics and other services. The station always takes credibility first, guests first, and high-quality service as its business purpose, and serves every customer with dedication and responsibility. Dazhou Railway Station is the fourth largest railway station in Southwest China and the second largest marshalling station in Southwest China. [Edit this paragraph] Dazhou topography The terrain of Dazhou City is high in the northeast (Daba Mountain Area) and low in the southwest (basin and hilly area). The highest point is Daduanbao, Jishang Township, Xuanhan County, with an altitude of 2,458.3 meters; the lowest point is Tianguan Village, Wangxi Township, Qu County, with an altitude of 222 meters. Daba Mountain is located in the northern part of Xuanhan, Wanyuan, with Mingyue Mountain, Tongluo Mountain and Huafu Mountain lying from north to south, dividing the city into three parts: mountainous area, hilly area and Pingba Mountain. Mountains account for 70.70% of the total area, hills account for 28.10%, and flat dams account for 1.20%. The mountains in the northern part are sharply cut and steep, forming mid- and low-mountain landform units; the central and southern parts are gentler, forming an equal valley landform unit. [Edit this paragraph] Dazhou Mountains Daba Mountain

The watershed of the Jialing River and the Han River, and the geographical boundary of the Sichuan Basin and the Hanzhong Basin. In the narrow sense, Daba Mountain only refers to Micang Mountain and Daba Mountain in the border areas of Sichuan, Shaanxi and Hubei provinces. It stretches more than 500 kilometers from east to west, so it is called Qianli Bashan. Referred to as Bashan. Guangdong Daba Mountain is the general name for the border mountainous areas of the four provinces of Sichuan, Gansu, Shaanxi and Hubei, including Motian Ridge extending to the west of Micang Mountain and Shennongjia Mountain extending to the east of Daba Mountain. Daba Mountain is located between the Qinling geosyncline in the north and the Sichuan platform syncline in the south. Due to the control of the two major structural lines in the north and south, the mountain is a parallel fold belt composed of a series of regular anticlines and synclines, but the east and west two The part is slightly to the north and the middle part is slightly to the south, so it may be called the Daba Mountain arc-shaped fold belt.

The strata are ancient and mainly composed of limestone, dolomite, metamorphic rock, and sandstone, with local granite distribution. The first two have karst landforms such as peak clusters, caves, and underground rivers. The famous ones include Guangyuan Long Cave, Wangcang Huangyang Cave, and Tongjiang Zhongfeng Cave. The ridge is composed of hard crystalline limestone, which is thick and majestic after rising and eroding. The altitude is about 2000 meters, Wuxi Taiping Mountain is 2797 meters, and the highest Shennongjia in Hubei is 3105.4 meters.

Huaying Mountain

Huaying Mountain originates from the southern foot of Daba Mountain. It is the boundary mountain between the parallel fold ridges and valleys in eastern Sichuan and the hills in central Sichuan. It runs from northeast to southwest and spans Dazhou. , Guang'an, Chongqing and Neijiang, Zigong, Luzhou, Yibin and other cities, with a total length of 325 kilometers. Because "the top of the mountain is covered with snow, it looks like Qiong Yao scattered on the ground and the mountain covered with crystal jade", so it is named Huaying Mountain. Huaying Mountain extends from the south of Qu County to the northeast of Guang'an District, south to Baoding at the junction of Linshui County and Huaying City, and extends into Yubei District and Hechuan City of Chongqing City. Huaying Mountain is about 70 kilometers long in Guang'an City, generally 6 kilometers wide, and 9 kilometers at its widest point. From Linshui Temple Liangzi to Baoding, it is the highest part of the entire Huaying Mountain. The highest mountain peak is 1,704 meters above sea level, and it is also the highest peak in the Sichuan Basin. Huaying Mountain is rich in mineral deposits, dense forests, a wide variety of animals, and natural and cultural landscapes with great tourism development value. In 1993, Huaying Mountain was listed as a provincial scenic spot.

Tongluo Mountain

Tongluo Mountain is the second mountain range in the parallel fold ridge and valley area of ??eastern Sichuan. Starting from the northern end of Leiyinpu Mountain in Da County, it runs from northeast to southwest, spanning Dazhou, Dazhu County, Linshui County and Changshou County, Yubei District, Nan'an District, Banan District, Qijiang County and other counties in Chongqing City, ending at Tiantai Mountain on the north bank of Qijiang River. It has a total length of 260 kilometers, a width of 5 kilometers to 10 kilometers, and an altitude of generally 600 meters to 1,000 meters. The highest peak, Wanfeng Mountain, is in Long'an Town, Linshui County, with an altitude of 1,054 meters. Because the Yangtze River cuts across the mountains east of Chongqing City, it forms the Tongluo Gorge. The water in the gorge hits the rocks like the sound of a gong, so it is named Tongluo Mountain. Tongluo Mountain enters Linshui County from Da'ancao, Dazhu County, and passes through the towns of Xinzhen, Taihe, Lengjia, Chang'an, Liangban, Jiufeng, Yaofeng, Yaotan, etc., with a length of about 65 kilometers, including Wanfeng Mountain to Xian The Yingshan section has steep mountains and deep valleys. It is the highest section of Tongluo Mountain. The axis of the anticline has been eroded for a long time, taking the shape of "one mountain, two ridges and one trough". The trough is dotted with residual hills, dissolved depressions, and sinkholes, and has a typical karst landscape. Valleys such as Daping, Guirencao, Liangban, and Changjiacao have flat and open terrain, densely populated areas, contiguous fertile fields, and rich products. There are many karst caves on both sides of the trough and valley, especially the area from Jiufeng to Yaofeng Yulinhe Small Three Gorges. There are more than 30 caves, among which Jiulong Cave, Moon Cave, Lanjia Cave, Hejia Cave, Lion Cave and Fairy Cave have the best views. There are 7 hot springs in the Xiaonanhai area of ??Yulinhe Xiaosanxia, ??which are rich in trace elements beneficial to the human body. Tongluo Mountain has more than 10 kinds of mineral deposits, including 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, blocking out the sky and the sun. Rich in masson pine, fir and cypress, it is an important timber forest base in Linshui County.

Mingyue Mountain is the third mountain range in the parallel folded valley area of ??eastern Sichuan. It starts from Kaijiang County in the north, runs from northeast to southwest, and spans Dazhou, Liangping, Dazhu, Linshui, Dianjiang, Changshou, Yubei District and other counties and districts, ending at Yongxingchang, Banan District. The total length is 232 kilometers, the width is 4 to 6 kilometers, and the general altitude is 700 to 1,000 meters. The Yangtze River cuts across the mountains between Yubei District and Banan District, forming a canyon. There are "round holes like a full moon" on the cliffs on the gorge bank, so it is called Mingyue Gorge, and the mountain is named after the gorge.

Mingyue Mountain

Mingyue Mountain enters Linshui County in Xiayancang, Dazhu County, between Dianjiang, Changshou County and Linshui County, and is the watershed of Dahong River . It passes through the towns of Hulin, Xingren, Shichu, Bal'er, Fenghe, Lijia and other towns, and is about 47 kilometers long. From Yaguai Mountain in Hulin Township to Zhongcheng Village in Shiju Township, there are strange peaks, criss-crossed cliffs, deep mountain streams and splashing hanging springs. Its highest peak is Xingren Tuya, with an altitude of 1179 meters, making it the third highest peak of Mingyue Mountain. The section from Zhongchengzhai to Xinglong Bay has a gentle slope, the top of the mountain is round, there are no obvious peaks, and the relative height difference is not large. The mountain body is in the shape of "one mountain, two ridges and one trough", but the troughs and valleys are mostly in Dianjiang and Changshou counties. The troughs and valleys only extend into Jiangjiacao and Dabangou in Li's hometown. Mingyue Mountain has coal, natural gas, gypsum and other mineral deposits, and is rich in forest resources. It is the largest timber forest base in Linshui County and plays a good role in water conservation of the Dahong River. The forest vegetation is dominated by masson pine, fir and other artificial forests. In the deep valleys around Yangcha Gou, Daoxu Gou and Longwang Gou, there are relict plants called Cyperophora spinulosa.

This ancient plant was on the verge of extinction during the Quaternary Ice Age. It is now rare in the world, so it is called a "biological living fossil" and has great scientific research value and tourism development value. [Edit this paragraph] Dazhou Hydrology The rivers in Dazhou City mainly belong to the Jialing River system, a tributary of the Yangtze River. They originate from Daba Mountain and are distributed in a dendritic shape from north to south. The Qianhe River, the Zhonghe River and the Houhe River merge into the Zhouhe River and the Bahe River merge into the Qujiang River in Sanhui Town, Qu County, flowing 300 kilometers southward into the Yangtze River. There are 53 rivers with a drainage area of ??more than 100 square kilometers and 15 main rivers with a drainage area of ??more than 1,000 square kilometers. There are 9 navigable rivers in the country, namely Qujiang, Zhouhe, Bahe, Qianhe, Houhe, Zhonghe, Tiexihe, Qingxihe, and Linggangxi. Basically, they are composed of Qujiang, Zhouhe, The waterway transportation network of the main stream of the Ba River covers four counties (cities) in the city. The navigable mileage of each river varies, and the carrying capacity is less than 100 tons.

Qujiang

Qujiang belongs to the Jialing River system. The Jialing River has many tributaries, the two largest being Fujiang River and Qujiang River. The Qujiang River originates from Daba Mountain, also known as Diving, and flows through Bazhong and Dazhou to Sanhui Town in Qu County, where it is called Qujiang. The total length is 720 kilometers; the Fujiang River originates from Xuebaoding in Minshan Mountain and flows through Mianyang, Deyang, Suining, Guang'an and other hilly areas in central Sichuan have a total length of 700 kilometers; the two rivers converge at Hechuan and Jialing Rivers. Qujiang River starts from Sanhui Town in Qu County and flows from north to south in Qu County, passing through eight districts including Sanhui District, Tuxi District, Linba District, suburban area, Qujiang Town, Xiandu District and Langya District. , town, 21 townships, among which there are tributaries such as Yongxing River, Guixi River, Liujiang River, and Zhongtan River. It exits Wajiaotan, Langya Township, the southernmost part of Qu County, and enters Qinlao Village, Xiaoxi Township, Guang'an County. It runs diagonally through the middle of Guang'an County from northeast to south-west, passing through Hengsheng District, Stalagmite District, Guange District, and Daishi District. , Kwuntang District, Xiexing District, Guangfu District and Huaying City, from Laojun Village, Hualong Township, Guangfu District, to Zhonghe District and Luodu District, Yuechi County.

Tongchuan Bridge

The Han-Chongqing Highway was the shortest route for transporting Soviet anti-Japanese aid materials to Chongqing. It was known as the "East Sichuan-Shaanxi Road" at the time. It is more than 90 kilometers shorter than Sichuan-Shaanxi Middle Road and more than 270 kilometers shorter than Sichuan-Shaanxi Road. Therefore, the Wuhan National Government ordered the construction in February 1938. Ding Gongnan arrived at the Han-Chongqing Highway in August of that year and successively served as the captain of the Second Survey Team and the Section Chief of the Second General Public Works Section, responsible for the survey, design and construction of the northern section of Daxian County. In June 1940, due to the decrease in supplies from the Soviet Union to aid China, the Han (Central) and Xuan (Han) Sections were ordered to stop construction, and the original Han-Xuan and Xuan-Chongqing Engineering Offices were reorganized into the Han-Chongqing Highway Engineering Office, with Ding Gongnan as the director of engineering. The company is responsible for the testing and construction of the 417-kilometer highway from Wanyuan to Chongqing. Among them, the area north of Daxian County has complex terrain and arduous projects, making line selection very difficult. However, the Hanyu Road has better institutional, personnel and financial conditions and stricter technical standards, which makes surveying and line selection more difficult. With the joint efforts of him and the majority of technical staff, the Han-Chongqing Highway became a highway with better linear standards at that time and was well received. There are many bridge and culvert projects on this road, most of which adopt stone arches and reinforced concrete permanent structures. For this reason, bridges and ferries with a span of more than 10 meters were determined at that time, and a bridge and ferry engineering office was set up to be responsible. However, the location of the Tongchuan Bridge, which was built in early 1941, was determined by Ding Gongnan when he was the captain of the Second Survey Team. The bridge is located near the county seat of Daxian County and spans the Zhou River. The Zhou River is formed by the confluence of the Front River, the Middle River and the Back River. During flood season, flash floods occur and water flows rapidly. After repeated surveys, he selected the bridge location at that time. The water flow was straight and the foundation was good. The bridge was designed by the Bridge Crossing Engineering Office as a reinforced concrete cantilever bridge with 11 holes and a span of 20 meters. Together with the approach bridge, the entire bridge has a maximum length of 300.94 meters and a designed load capacity of 15 tons. It was the permanent highway bridge with the largest cantilever structure at that time. There are archways at the north and south ends of the bridge, and the banners are engraved with the three characters "Tongchuan Bridge" inscribed by Zhang Jia'ao, Minister of Transportation of the Chongqing National Government, and Zhao Zukang, Director of the Highway Management Department.

On the archway at the south end, there is also a couplet written by Zhou Fengjiu, a famous highway expert who was an assistant at the General Highway Management Office at that time: "Stacking stones makes a rainbow, and everyone is happy on this day. I wish Tongchuan victory; I help people reach the other side, and I hope that in the future The whole people unite to complete the merits of the founding of the country." Remember the grand occasion of the completion of the new bridge and express the desire to unite and build the motherland. All this shows that the completion of this bridge played an important role in supporting the Anti-Japanese War.
