Cultivated land area accounts for only 18.7% of the total land area, about 313,300 hm 2 (4.7 million mu), of which 85,300 hm 2 (128 million mu) of land. The water system belongs to the Pearl River basin, rich in water and soil resources, but extensive agriculture, drought and water shortage, the urgent need to develop water irrigation, strengthen management and improve operating efficiency. 1 Current Status of Existing Water Conservancy and Hydropower Projects in Qianxinan Prefecture Guizhou Province has a rich water resources and hydropower resources in Guizhou’s southwestern state with a total annual runoff of 9.475 billion m 3 and an installed capacity of 375,300 kW of hydropower. After the founding of the People’s Republic of China for 50 years, especially during the 20 years of reform and opening up, as of the end of 1998, 4294 middle and small scale water conservancy and hydropower projects have been completed in Qianxinan Prefecture, with a total fixed assets of 390 million yuan, The total area of 1733hm ~ 2 (2.6 million mu), designated protection area of 2400hm2 (36000 acres), and Tianshengqiao reservoir area
