Abstract以ArcGIS9.2为平台,构建了基于土地利用/覆被的生态系统供水发电服务物质量和价值量评估模型。包括根据降雨和潜在蒸散发及下垫面特征参数,结合耗水量模拟集水区产出的年供发电水量。由评估水电站的特征参数和集水区每个象元对总供水量的贡献率,采用水能资源公式模拟集水区生态系统发电贡献量的空间分布特征。价值量模型则结合电价及运行成本进行计算。在二滩水电站及其集水区进行了模型的运用。结果表明:2000年,模型模拟为二滩电站贡献汇流的实际供水量达到311.63*10~8~m~3·a~(-1)。在水电站设计使用年限内集水区产水总发电量为5763.84*10~8kW·H,发电总净利润为888.66*10~8Yuan,其中草地生态系统的贡献率最大,达到54.23%。集水区东南部的康定-九龙冕宁喜德西昌一带生态系统供水对于二滩电站发电收益的贡献最大
Other AbstractOn the platform of the integrated Geographic Information System(GIS)software package ArcGIS9.2,a model was developed to simulate the ecosystem service of water supply and power generation and its economic value based on land use/cover.This model simulates the annual water supply of watershed for power generation by taking input parameters of precipitation,potential evaportranspiration,characteristic parameter of underlying surface and water consumption.Spatial distribution features of the ecosystem power generation over the watershed can be simulated using the characteristic parameters of the hydropower stations studied,each pixels contribution ratio to the total water use by hydropower production and the formula of hydropower resources.The economic value of ecosystem service is determined by electricity price and total annual operating costs.In a case study of the Ertan hydropower and its watershed,the simulation showed an actual water supply of 311.63*10~8m~3·a~(-1)to this hydropower in 2000 and a total power output of 5763.84*10~8kW·H and a total net present value(NPV)of power generation of 888.66*108 Yuan in the remaining years of the Ertans expected lifetime.The grassland contribution ratio 54.23%to the ecosystem service value was higher than those of the other factors,and the higher contribution ratios of water supply to the Ertan power output come from southeastern part of the watershed such as Kangting,Jiulong,Mianning,Xide and Xichang.
