Comprehensive Evaluation Model of Environmental Quality in Ecological Reserve

Abstract

The environmental quality of the ecological protection zone directly affects the water quality and air quality of the area, thereby affecting the quality of people’s life. This paper constructs the evaluation index system of the environmental quality of the ecological protection area and determines the classification standards of each index, proposes the extension evaluation method of the environmental quality of the ecological protection area, and uses the entropy weight method to determine the weight of each level of index. Its purpose is to understand the development trend of environmental quality in all aspects of the ecological reserve through the dynamic evaluation of the environmental quality of the ecological reserve, so as to take corresponding countermeasures to promote the healthy development of the area. The constructed model was used to dynamically evaluate the environmental quality of the ecological reserve in Zhangjiakou City from 2008 to 2019. The research results show that the environmental quality gaps in different aspects of the ecological reserve of Zhangjiakou City are relatively large, and the overall regional ecological environment characteristic value is decreasing year by year, reflecting that the environmental quality of the ecological reserve of the region is getting better year by year.
