natural resources

water resource

1、 Surface water

Rainfall is the main source of surface runoff in Ningyuan county. The annual water volume is about 2.69 billion cubic meters in wet year and 1.27 billion cubic meters in dry year. The runoff from April to July accounts for 56% of the whole year. The water volume in the South and North mountain areas is 1.1 million cubic meters per square kilometer. The eastern hilly area is only 610000 cubic meters. The annual inflow from Lanshan county is about 108 million cubic meters. During the 26 years from 1978 to 2003, the average annual runoff depth of the county was 784.2 mm, and the average annual runoff was about 1.98 billion cubic meters. The water quality of the four major rivers in the county is good except that the first section of Lingshui from the county paper mill to caojiatan is polluted, and the arsenic and mercury content of Renshui from Xinkai antimony mine to the downstream reaches of 1000m exceeds the standard and is not suitable for drinking water. According to the segmented calculation of each river, the theoretical reserve of hydropower in the county is 112400 kW, of which 68615 kW is available for development and 35090 kW has been developed. There are 60 rivers in Ningyuan with a length of more than 5 kilometers and a drainage area of more than 10 square kilometers, 59 of which originate in the county and 1 in other counties. Except that Huangsi river flows into Baishui of Qiyang County, xiaxiahe river flows into chongshui via Jiahe and Xintian, other rivers flow into Xiaoshui via Xianxi.

Chung Shui

Before the Republic of China, it was also known as capital stream. The main stream of Ningyuan river.

After the confluence of the East and West Chung water, it continued to flow southward, passing mianhuaping, lijiapu, Renhe, shuangbanqiao, Baohe, to the Lianghekou of Tiantang Town, where it met with the Lingjiang River and poured into Xiaoshui at Qingkou of Daoxian county. The flow from Liangjiangkou to Lianghekou is 40.8 km. There are 41 tributaries in chongshui, covering an area of 963.5 square kilometers, with a drop of 520 meters and a slope of 6.3 ‰. The average annual discharge of the estuary is 20.52 second cubic meters, with an average runoff of 679.3 million cubic meters. The theoretical water energy reserve is 28147 kilowatts, and the actual development capacity is 24554 kilowatts.

Cool water

Also known as Lingjiang, it was named Chishui in Tang Dynasty. There are two main tributaries in the upper reaches: one originates from tuanyuan mountain in Lanshan County, and the other from wajing chaluoping.
