Research on Saihanba Nature Reserve Based on Comprehensive Evaluation Method and Cluster Analysis

Abstract

In this paper, we analyze the environmental impact of Saihanba Nature Reserve by constructing a comprehensive environmental assessment model. Specifically, we use the entropy weight method to determine the weight of each secondary index and quantitatively study the environmental changes before and after the construction of Saihanba. In addition, we established a mathematical model to evaluate the influence of Saihanba's ability to resist sand and dust storms and quantitatively evaluated the effect of Saihanba's ability to resist sand and dust storms. Finally, we investigated the scale of the constructed ecoregions using a clustering algorithm.
