Analysis on the coupling degree of water source ecological environment based on 3S technology

Abstract

In order to overcome the problems of low classification accuracy, high error and long time in traditional water source eco-environmental coupling model analysis method, a water source ecological environment coupling degree analysis based on 3S technology is proposed. According to the classification results of water source ecological environment features, the water source ecological environment evaluation matrix is constructed, and all indexes are normalised. The index weight is estimated by calculating the information entropy of the evaluation index, and the water source ecological environment coupling degree model is constructed according to the index weight to complete the analysis of water source ecological environment coupling degree. The experimental results show that the accuracy of surface feature classification is always above 97%, the relative error rate of water source ecological environment coupling analysis is always below 3.9%, and the average analysis time is only 0.62 s.
