Aiming at the evaluation of the impact of Saihan dam on ecological environment construction, this paper selects several
representative indicators to evaluate the ecological environment through the ECCI evaluation system, and judges the impact
degree of Saihan dam by establishing the relevant model of the impact of Saihan dam on ecological environment construction.
Based on the existing evaluation system of ecological civilization construction in China, by collecting various data and consulting
relevant literature, three categories and seven indicators with great correlation before and after the restoration of Saihan dam are
selected, and the judgment matrix is constructed by analytic hierarchy process, so as to obtain the weight value of each index. The
factor analysis is carried out by constructing the matrix, and the vector is normalized, The consistency is used to test the indicators,
and then the data before and after the restoration of Saihan dam are substituted for comparative analysis.
