Business card map: Nanbao Township, Qionglai City, Yuxi River
Chinese name: Yuxi River alias: Lushanhe belongs to the water system: the tributary of the Yangtze River, the Qingyi River, the upper Yuan Baoxing River flows through the area: Qionglai City, the birthplace of Lushan County: the main tributary at the southern foot of Touyan at the junction of Lushan County and Wenchuan County: Huang Shuihe and Taiping River length: 1 13km River area: 1397km2 Estuary. Lushan River is the longest first-class tributary in Qingyi River system. There are two sources in the upper reaches of Lushan main stream: Heishui River and Huangshui River. Heishui River is 2 kilometers longer than Huang Shuihe and should be listed as the positive source. Heishui River originates from the southern foot of Duantouyan at the junction of Lushan County and Wenchuan County, and flows southward into small tributaries such as Nabaiyinggou, Daxuetanggou, Sanchagou and Maiyanglingou. It is called Dachuan River after it joins Huang Shuihe in the middle and upper mouth. Dachuan River flows eastward at the mouth of Dongxiazigou, eastward at Nacaomixi and Xiaohezi near Dachuan Town, southwest at the foot of Nabaishi River in the south of Duankou Mountain, and enters Qionglai City, renamed Yuxi River. Yuxi River was originally named Yuxi River or Yuxi River. Because the river is crystal clear, there are often fish swimming, and later it was mistaken for Yuxi River. Yuxi River is 9.3 kilometers long in Qionglai City, turns back to Lushan County in the north of Yulin Mountain, flows to Lunayan Creek in Yancun, Baosheng Township in the southwest, then flows to the Taiping River in Baosheng Township in the south, and then enters Jinji Gorge sandwiched between Jianfeng and Zhengxi Mountain. Jinjixia is one of the four major canyons in Lushan County, with a length of about 6 kilometers. In the gorge, the peaks and mountains are connected with the sky, and the water belongs to the peaks and mountains. The four seasons are green, and tranquility is better than Wuxia Gorge. The dam of Yuxi River Diversion Project crosses the canyon, crosses the Zhengxi Mountain Diversion Tunnel eastward, and intercepts Yuxi River, with an average annual flow of 78.8%. Xiakou is located in the ancient Qinglong Pass, surrounded by mountains and waters, and the city still exists. Yuxi River was renamed Longmen River after it left Jinji Gorge. The river winds in Lushan syncline and flows through Longmen, Longxing and Shenglong Township. After Qingyuan River was accepted at the southern end of Lushan County, it was called Lushan River. It flows south through Modong Town and joins Qingyi River at Sanjiangkou. Total length 1 13km, drainage area 1397km2. The elevation of the estuary is 645m, the discharge is 55.8 1m3/s, and the drop is 3595m. The theoretical capacity of hydropower is 3210.2 million kilowatts in the main stream and 428,550 kilowatts in the tributaries. Huang Shuihe, the main tributary, is the second largest tributary of Lushan River. Originated in the south foot of 5028 peak on the west side of Daxuefeng at the junction of Lushan County and Wenchuan County, the origin section is called Xiaogou, which was formed by melting ice and snow. After flowing to the southeast streams such as Naniujinggou, Shawangou, Luchanggou, Jinjixia Xiaogou and Ganhe, it flows into Dachuan River at the middle upper mouth. It is 29 kilometers long and has a drainage area of 20 1 km2. Estuary elevation 1720m, discharge 7m3/ s, and drop of 2740m. Heishui River, also known as Changshiba River, the upstream source of Yuxi River, originates from the east of Daxuefeng in Shuanghe Township, Dayi County and flows southward to tributaries such as Nabaiyinggou, Sanchagou, Maiyanglin and Lengjingou. Later, it was named Dachuan River (Yuxi River) in Zhongzuihui Huang Shuihe, leaving the county seat and flowing into Qingyi River via Lushan County. The river is wide at the top and narrow at the bottom, and the valley is deep, and individual river sections form alpine canyons. The main channel of this river in the county seat is 26 kilometers long, with a drainage area of 187 square kilometers, an average annual flow of 7.09 m3/s to 10.0 m3/s, a theoretical water storage capacity of 70,000 kilowatts and an exploitable capacity of 50,000 kilowatts. Taiping River is the third largest tributary of Lushan River. Originated in the south foot of the top of the pot cover, the first section is called Zhenghe; After turning to the southeast Navazi River, it turned to the south, and was renamed Lin Zhonghe after it was located in Namodao River, the resident of Lin Zhong Township. Taiping Town, Nahe was renamed Taiping River after being stationed in Taiping Town; Turn to the southeast and join the Yuxi River in Baosheng Township. It is 28 kilometers long, with a drainage area of 2 12 square kilometers. The elevation of the estuary is 840m, the flow rate is 8.47m3/s, the drop 1.560m, and the theoretical hydropower reserve is 33,200 kilowatts. Qingyuan River is the largest tributary of Lushan River. The upper reaches are in Baoxing County, and originate from the southeast foot of the mountain peak 2580 meters south of Muping Town. The first section is called Qingshui River, which was renamed Xichuan River after entering Lushan County. Xichuan River, formerly known as Xuchuan River, later mistakenly called Xichuan River, flows southeast to Shibao River, the resident of Shuangshi Town, and then enters Lingguan Gorge, about 5 kilometers long. Lingguan Gorge is a box canyon formed by cutting calcareous conglomerate under Xichuan River, and it is one of the four great canyons in Lushan Mountain. Huang Mao Slope in the east and Fangguan Mountain in the west are the ruins of Guling Pass. The plank road remains on the gorge wall. The grotesque rocks in the canyon are covered with steep cliffs; Looking up at the sky, there is only one line in the sky, which is known as "a line of sky in Shili Canyon"; Between the rock walls, vines and kudzu vines crawl and waterfalls plummet; The whole canyon is quiet and steep, comparable to Qutang. Xichuan River was renamed Qingyuan River after leaving the canyon, and it was named because it was mistaken for the main source of ancient Qingyi River. The river flows through Renjia and Qingyuan Township and flows into Lushan River at the southern end of Lushan County. It is 34 kilometers long and has a drainage area of 20 1.9 square kilometers. The elevation of the estuary is 660m, the flow rate is 7.48m3/s, the drop 1.050m, and the theoretical hydropower reserve is 2.41.000kW.. The water diversion and irrigation project of Yuxi River in Sichuan Province was built during the Cultural Revolution, which belongs to the project of "design, construction and transformation". The main canal is located in the mountainous area above 800 meters above sea level, surrounding Qionglai Mountains. The passing section is steep and the terrain and geological conditions are complex. The channel bed is mostly composed of slope layer and Ya 'an gravel layer, with loose structure and strong water permeability, which is a serious threat to natural disasters. Along the canal, there are 0/6 tunnels 12775 meters long, 0/8 aqueducts157 meters long, and 57 culverts (3606 meters long), and water conveyance structures account for about 33% of the total length of the canal. In addition, there are more than 500 buildings such as water diversion, drainage, sluices, bridges and culverts and overflow weirs. Due to the limitation of historical and natural conditions at that time, the engineering construction standard was low and the lining technology was poor. In operation, the problems such as river collapse, leakage and siltation are very serious, and there are many hidden dangers in the project, which is extremely difficult to manage. There are 98 main canals, branch canals and bucket canals (total length 1 148km) in the whole irrigation area, including: main canals (total length 5 1.5km), main canals, branch canals 16 (total length 80km) and 45 small and medium-sized reservoirs in the irrigation area. Yuxi River Irrigation Area Yuxi River Irrigation Area is one of the large irrigation areas in Sichuan Province. Yuxi River Irrigation District is located in the southwest edge of Chengdu Plain, between Minjiang River and Qingyi River. It spans Chengdu and Ya 'an, covering an area of 1748km2, with high terrain, mostly hills and terraces. The irrigation area has a population of 760,000, which mainly depends on agricultural production and Yuxi water diversion project for irrigation. The designed irrigation area of this project is 866,400 mu, and the designed water diversion flow is 34m3/s, which irrigates Qionglai, Pujiang, Ya 'an famous mountain and Lushan in Chengdu, and the current effective irrigation area is 620,000 mu. Yuxi River Irrigation District Management Office adheres to the concept of "serving the irrigation district", and cadres and workers work together with Qi Xin to strengthen internal management, increase investment in engineering renovation, actively create conditions and overcome difficulties. 1978, the water diversion project was put into operation. Under normal circumstances, the annual water supply lasts for 350 days, and the total water transfer is more than 620 million cubic meters, which completely ends the situation of "relying on the weather to eat" in the history of irrigation areas, and the grain output is large. Yuxi River Water Diversion Project has become the reliance of people's life in irrigation areas, and has played an important role in agricultural production and urban and rural economic development in four counties (cities).
