Mining area ecology comprehensive evaluation method based on optical and radar images

Abstract

The invention belongs to the technical field of geology, and provides a mining area ecology comprehensive evaluation method based on optical and radar images in order to solve the problem that mining area ecology comprehensive evaluation is incomplete in the prior art. Comprising the following steps: S1, acquiring and processing data of mining area ecological degradation risk assessment factors, determining weights of the mining area ecological degradation risk assessment factors, and establishing a mining area degradation risk comprehensive evaluation model; s2, acquiring and processing data of environment quality evaluation factors; determining a mining area environment quality factor weight, and establishing an ecological quality evaluation model; and S3, integrating the mining area degradation risk comprehensive evaluation model in the S1 and the ecological quality evaluation model in the S2 to construct an ecological comprehensive quality evaluation model so as to realize comprehensive evaluation of mining area ecology. According to the method, the objective weight is obtained by using the improved entropy weight method, the dynamic weight is obtained by using the network analysis method, and the evaluation result is obtained by using the weighted synthesis method, so that the evaluation result is more reasonable, and the accuracy of mining area ecological environment quality evaluation is ensured.
