Fuxi River

Fuxi River

Fuxi River is on the right bank of the lower reaches of Tuojiang River. Shangyuan Weiyuan River (Qingxi River) originates from liangmu mountain in Weiyuan County. The drainage area is 3472 square kilometers, the river length is 190 kilometers, the natural fall is more than 360 meters, and the average slope is about 1.9 ‰. It flows through Weiyuan County and Zigong City of Sichuan Province, and joins Tuojiang River at Fuxikou of Fushun County.

River form

The upper section of Fuxi River is divided by Rongwei dome low mountain, other tributaries of Tuojiang River and Yuexi river of Minjiang River system.

Among the watersheds, Jianzi mountain in Shunhe township of Rongchang County has the highest elevation of 959 meters, followed by Tuanbao mountain (804 meters above sea level) and Wumen mountain (745 meters above sea level), which are also the low dome mountains of Rongwei.

The terrain inclines from northwest to Southeast, and from low mountain area to Southeast, there are shallow hills and flat dams. Generally, the top of the middle and upper section is less than 500 meters above sea level, and the middle and lower section is less than 350 meters above sea level.

The upper source of Fuxi River flows from south to north to lianjiechang, turns East, and flows southward to Shanwang township at Guanyintan. In the reach from lianjiechang to Shanwang Township, two medium-sized reservoirs, namely, Changsha dam and Hulukou, are successively built. After leaving the reservoir, they continue to flow southward to naxinchang River on the right bank of Lianghekou, zigzag southeast, and pass Weiyuan County to Nani River on the left bank of qinglongzui and nalonghui River on the left bank of Jiepai, It continues to flow southward along the boundary between Zigong City and Weiyuan County. At the Shuanghekou of fenghuangqiao, Zigong City, it is called Fuxi River after naxushui River (Rongxi River) on the right bank. It zigzags eastward from Huikou to nachangtan River on the left bank of Yaoba Township, Fushun City. It flows southeast along the boundary between Zigong City and Fushun County. It passes through many river bends and bends. On the left bank, there are Dayan River, Shutan River, wangzi River, yangcha River and Dengguan river After arriving at nazhenxi River on the right bank of shimawan in Fushun County, it flows into Tuojiang River at Fuxikou.

Fuxi River Basin is in Northwest and southeast direction, the shape of the basin is similar to diamond, the water system is developed, and the branches are distributed evenly on the left and right banks.

There are 15 named primary tributaries, among which the main tributaries are Xinchang River, Nihe River, longhui River, Xushui River, etc.

hydrographic features

Fuxi River has a subtropical climate with warm winter, early spring, hot summer and cool autumn. The annual average temperature is 18 ℃, the average temperature in January is 7.5 ℃, the average temperature in July is 26.9 ℃ - 27.3 ℃, the maximum extreme temperature is 39 ℃, the minimum is - 2.7 ℃, and the frost free period is 327 days. The average annual precipitation for many years is 1000-1080 mm, mostly concentrated in June-September, and the maximum annual precipitation is 1876.8 millimetres at Zigong station The minimum annual precipitation of Rongxian station was 680.1 mm (1972).

Rainstorm and flood mostly occurred in the upper part. According to the investigation of historical flood at Puziwan feldspar station of Weiyuan River, the highest flood level in August 1888 was 307.59m, and the maximum discharge was 1650 m3 / S; the flood level of Rongxi River upstream of Xushui River in 1962 was 350.80m, and the maximum discharge was 1528 m3 / s.

Development conditions

The theoretical water energy reserve of Fuxi River Basin is 12000 kW. In addition to the Rongwei dome low mountain in the northwest of Shangyuan, the hilly area is more than 50% of the total area, so the river should be developed step by step and irrigated. From 1957 to 1981, the total capacity of the built project was about 400 million cubic meters, and the irrigated area was about 600000 mu.

Among them, there are three medium-sized reservoirs with a total capacity of 134 million cubic meters, 376 kilometers of main and branch canals, and an irrigation area of 310000 mu. The larger ones are Changsha dam reservoir (with a total capacity of 45.3 million cubic meters and an installed capacity of 1250 kW) and Hulukou reservoir (with a total capacity of 75.8 million cubic meters and an installed capacity of 1250 kW). The distance between the two reservoirs is 15 km, and joint operation is implemented. Combined with the two main canals, the industrial and agricultural water and people's living water in Zigong City and Weiyuan County were solved.

The navigation of Fuxi River has a long history. In 1940, the construction of Fuxi River channelization project was carried out, 73 kilometers from Niujiaotuo to Dengguan. In 1945, the construction of Weiyuan River channelization project was carried out twice, and 16 ship locks were built, which can be used for navigation of about 5 tons of ships.

After the founding of the people's Republic of China, the construction of various shipping projects continued. The whole river was basically channelized, with a navigation depth of 1.2-1.5 meters. The section from liujiatan to Lijiawan of Fuxi River has a voyage of 132 km. It can pass 8-30 ton wooden barges and 20-80 horsepower motor boats.

Rice accounts for more than 40% of the total grain, followed by wheat, corn, beans and sweet potato; economic crops are mainly rape, peanut, sugarcane, tea and jute. The northern part of the mine is rich in coal and iron, while the southern part is rich in well salt.

Zigong, the capital of salt, is one of the important well salt producing areas in and out of the province since the Eastern Han Dynasty. In Da'an District of Zigong City, there are 160 million years old silicified wood and dinosaur fossils, and the "Zigong Dinosaur Museum" has been established in Dashanpu. The traffic and transportation in the basin is mainly by highway, which has formed a network, and Chengdu Yibin railway passes through. Water transportation has a long history. Zigong well salt, Rongwei coal and iron and other materials are basically sold by water transportation.

Basin economy

Fuxi River is located in Sichuan Province. It flows from west to East in the upper reaches of the Yangtze River and passes through Zigong City. It is the main tributary of Cangjiang River in the city. The basin is rich in agricultural resources and developed in industrial production. The total industrial output value accounts for more than 70% of the total industrial output value of Zigong City. It is the heart of Zigong City. Fuxi River flows out the prosperity of Zigong today, and also flows many beautiful and moving folk legends. The section from zhangjiatuo to Wangye Temple shows a prosperous urban scene. The "heart" of Ziliujing in the past, the largest commodity distribution center in Sichuan, known as "Sichuan Wall Street", is located along Binjiang Road, with tall buildings and trees.

The mother river in Zigong City is mainly the Yangtze River system, and the downstream section of Tuojiang River flows through the city for 127 km. Fuxi River is the main tributary of Tuojiang River in the city. There are Xushui River and Weiyuan River in the upper reaches of Fuxi River, with a total area of 3490 square kilometers. In the west of the city, Yuexi river passes through Rongxian from north to south, belonging to the Minjiang River system

Fuxi River, originated from Jianshanzi in the north of Rongxian County, was called Rongxi River in ancient times. From the Qing Dynasty to the beginning of this century, it was also called Zijing River and Yanjing River, and was called Rongxi River and Rongchuan River in ancient times. It is 146 km long and belongs to the Minjiang river system. In Fushun dengjingguan, the name was determined only during the period of Anti Japanese war.

Fuxi River flows from west to East through 13 townships, 4 streets, 47 villages and 8 neighborhood committees. Along the main stream, there are many important towns, streets, organs, factories, mines and schools. The basin area is rich in agricultural resources and developed in industrial production. The total industrial output value accounts for more than 70% of the city's total industrial output value. It is the heart of Zigong City.

Thanks to the unremitting efforts of Zigong people, Fuxi River shows its beautiful posture. The green hills are reflected on the wide water surface, and the green lawn is on the bank. It has become a unique natural landscape of the city.

There are eight sceneries: "ziliugujing", "Hefu Renjia", "Yandao heritage", "colorful city", "vicissitudes of ancient temples", "Longchi calling fish", "Xiaodu at the end of the river" and "Fuxi Pastoral". The leisure bars, teahouses and pedestrian streets along the coast have become good places for people's leisure and entertainment. They are affectionately called "the Bund of Zigong" by Zigong people.

Historical development

In the late Qing Dynasty, wells (brine absorption) and cooking stoves (salt boiling) were scattered along both sides of Fuxi River. Therefore, Fuxi River was once known as "Yanjing River". Ziliujing, zhanjiajing, Wangjiajing, taiyuanjing and other "shangwujing" and "xiawujing" along the river all had a golden age of production and management.

In ancient and modern history, it was responsible for more than 80% of the transportation volume of well salt in Yandu. In the river, "long boats" and "barges" shuttle back and forth in an endless stream. Dengjingguan, which is located in the lower reaches of the river, was once in the heyday of "salt boats gathering, masts and sails weaving" for a long time.

In the past, Fuxi River had very low transportation capacity, steep river slope, narrow riverbed and dense dangerous shoals. When transportation across the beach, it is necessary to "lift the load" and release it after blocking the water, which often leads to the tragedy of ship destruction and human death.

With the development of Zigong's salt industry, the river has gradually changed from building sand weir, stone weir and plate weir to building weir and sluice to sailing. After the outbreak of the Anti Japanese War, Zigong well salt was ordered to increase production and the export volume of salt increased, so gates such as "Lidui" and "Yonggong" were built in zizidang, Yantan and dengjingguan.

From then on, the river was smooth and the transport capacity doubled. Even the 80 horsepower motor boats galloped on the river, whistling in the fields.

In recent years, due to the attention of Zigong municipal Party committee, municipal government and all levels of departments in Fuxi River Basin, the environmental protection policies have been seriously implemented, and the greening projects along the main stream of Fuxi River have been widely carried out. Now a "green corridor" is winding in Zigong from West to East, which is magnificent.

Legend

The Fuxi River brings out the prosperity of Zigong today, and also flows many beautiful and moving folk legends. There are 24 beaches. The beach looks at my mother. The story of "twenty four wangniangtan" tells us that after the Jiaolong completed the right fruit, on his way to the sea, he looked back at his mother 24 times, leaving a trace every time. These traces are today's 24 beaches, such as chongtan, Xiantan, Yantan, Hongyan beach, Boji beach, Laoya Beach, and Sanmei beach.
