This paper mainly studies the ecological evaluation of Saihanba. First, this paper calculate the Pearson correlation coefficient of the collected Saihanba data indicators, and after obtaining their significant correlations, because too many indicators are not conducive to the calculation, perform cluster analysis on the data, due to the K-means clustering method The subjectivity is too strong, use systematic clustering method to cluster the target, and use the elbow cri-terion to obtain the K value. Finally import the classified data indicators into MATLAB, and use the entropy weight-TOPSIS model to score and quantitatively evaluate Saihanba's environmental rating.
