摘　　要：枯水期是水资源短缺地区河道生态基流保障的关键期,枯水期河道生态基流的功能包括生态环境功能(避免河道断流、维持湿地生态系统、水质净化、营养物质输移)、自然功能(水文循环)和社会功能(水产品生产、休闲娱乐景观、提高生活品质)。这些功能可借鉴与应用资源环境经济学方法来计算价值,再加和得到河道生态基流的总价值。以渭河宝鸡段林家村水文站断面为例对所建立的方法进行测算和实例分析,结果表明,2010年渭河宝鸡段河道生态基流功能价值中,生态环境功能价值(67517万元)>自然功能价值(15463万元)>社会功能价值(12199万元);总价值为95179万元,单位水量价值为12.56元/m3。Dry season is the critical period of ecological base flow in water shortage areas. Ecological base flow in dry season has several functions： eco-environmental function（avoiding dried-up river, maintaining wetland ecosystem, water purification, and nutrients transportation）, natural function（sustaining hydrologic cycle）, and social function（offering fishery production, entertainment and landscapes, and improving life quality）. The values of these functions could be calculated using the method of natural resources and environmental economics, and then their sum is the total value of ecological base flow. To verify and demonstrate such a method, we have taken a case study of the Linjiacun hydrologic station on the Wei River. The results showed that, of the functions of ecological base flow in the Baoji reach of this river in 2010, the value of eco-environmental function（675.17 million yuan） was higher than that of natural function（154.63 million yuan） which exceeded the value of social function（121.99 million yuan）. And the total value of 951.79 million yuan was calculated, for the value of unit ecological base flow 12.56 yuan/m^3.
