Abstract:

Ecosystem service functions of hydropower project involves in many factors.The various factors are interrelated,and logical relationships are very complex,but they often have a hierarchical structure.Each of these factors contributing to the system service function has its own attributes;however,it performs the fuzzy characteristics in the actual measurement.Aim at the shortcomings of commonly used alternative evaluation methods (such as market value,opportunity cost,shadow project method,travel cost method,protection cost method,etc.),this paper put forward a new AHPFUZZY method by combining analytic hierarchy process and fuzzy programming.Many kinds of factors were considered in the method,avoiding the limitations of only a few criteria to consider.At the same time,a more objective affecting degree value was given through the hierarchical structure analysis.It would improve the reliability of reservoir ecosystem services function comprehensive evaluation.
