Abstract: According to the concept of ecological civilization, the existing ecological environment problems of the reservoirs in Hunan Province was sorted out in this paper, and the evaluation index system of ecological reservoir projects in Hunan Province was built from reservoir ecology, reservoir occupied area, ecological building materials and environment. Then the index weights of the evaluation system was determined by the analytic hierarchy process(AHP). The weight coefficient of reservoir ecology was 0.56, accounting for the largest proportion of reservoir ecological indicators. The weight coefficients of reservoir occupied area, ecological building material and environment were 0.12, 0.04 and 0.29 respectively. Taking the Baiyun Reservoir in Hunan Province as an example, calculation results showed that its ecological level was 0.382, and its overall ecological situation was regarded as general.
