摘　　要：以清江流域隔河岩水电开发为研究对象,采用混合分析法对水电开发全过程的综合碳减排效益进行估算。结果显示,隔河岩水电站单位发电碳排放为33.22 g CO_(2eq)/(kW·h),远低于火力发电。水电开发衍生的旅游业可减排228.21万t CO_(2),航运可减排106.03万t CO_(2),衍生行业具有显著的碳减排效益。隔河岩水电开发综合年平均碳减排效益为297.55万t CO_(2eq)。水电开发具有非常明显的碳减排效益,水电开发是碳减排的有力手段;同时衍生行业往往具备低碳性质,在开发过程中需统筹考虑衍生行业的引导,进一步增加碳减排效益。With Geheyan hydropower development in Qingjiang River Basin as analysis object,the comprehensive benefit of carbon emission reduction in the whole process of hydropower development is estimated by hybrid analysis method.The results show that the carbon emission per unit power generation of Geheyan Hydropower Station is 33.22 g CO_(2eq)/(kW·h),which is much lower than that of thermal power generation.And the tourism industry derived from hydropower development can reduce 2282100 tons CO_(2),the shipping industry derived from hydropower development can reduce 1060290 tons CO_(2).The derivative industry has significant benefits in reducing carbon emissions.The comprehensive annual average carbon emission reduction benefit of Geheyan hydropower development is 2975500 tons of CO_(2).Hydropower development has very obvious benefits of carbon emission reduction,and it is a powerful means of carbon emission reduction.At the same time,derivative industries often have a low-carbon nature.In the development process,we need to consider the guidance of derivative industries as a whole to further increase the benefits of carbon emission reduction.
