一、资源与开发现状陕西有黄河、长江两大水系。黄河流域的年径流量占全省径流的26.5％,长江流域的年径流量占全省的73.5％,平均年径流量1390亿立方米。境内拥有流域面积在100平力公里以上的河流583条,其中流域面积在5000平方公里以上的河流13条。全省水力资源的理论藏量1438.46万千瓦;(?)容量为666.56万千瓦,其中小水电为179.33万千瓦,详见表一。陕南是小水电资源的主要分布区,占全省可开发小水电资源的76.1％,其次是关中占19.3％,陕北仅占4.6％。
First, the status of resources and development Shaanxi has the Yellow River, Yangtze River two major water systems. The annual runoff in the Yellow River Basin accounts for 26.5% of the total runoff in the province. The annual runoff in the Yangtze River Basin accounts for 73.5% of the province’s average annual runoff of 139 billion cubic meters. There are 583 rivers within the territory of the basin with an area over 100 km2, of which 13 are river basins with an area of more than 5000 km2. The province’s theoretical reserves of hydraulic resources 14.3846 million kilowatts; (?) The capacity of 6.6656 million kilowatts, of which 1.9333 million kilowatts of small hydropower, as shown in Table 1. Southern Shaanxi is a major distribution area for small hydropower resources, accounting for 76.1% of the province’s small hydropower resources that can be exploited, followed by Guanzhong 19.3% and Northern Shaanxi only 4.6%.
