根据植被类型、坡度和土壤类型，分析了兴山县集水区内不同植被地块调节水量的能力。并且根据水能学的原理，分析了枯水期和洪峰期葛洲坝水电站的发电量与水流量的关系，建立了水流发电模拟模型。在上述分析的基础上，评估了兴山县境内生态系统调节香溪河等河流的水量，改善长江全年来水的均匀度，提高葛洲坝水电站发电效率的经济价值。
According to the types of vegetation, slope and soil types, the ability of adjusting water quantity of different vegetation plots in Xinshan catchment area was analyzed. According to the principle of hydraulics, the relationship between power generation and water flow of Gezhouba Hydropower Station during the dry season and flood peak is analyzed, and a simulation model of hydroelectric power generation is established. On the basis of the above analysis, the economic value of Xichang County’s ecosystem in regulating the water flow of Xiangxi River and other rivers, improving the uniformity of the Yangtze River water throughout the year and improving the power generation efficiency of Gezhouba Hydropower Station was evaluated.
