基于熵权-主成分分析的区域生态承载能力评价分析

Evaluation and Analysis of Regional Ecological Carrying Capacity Based on Entropy-Principal Component Analysis

基于生态承载力的内涵、特性,构建区域生态承载力的评价指标体系,在此基础上建立基于熵权法和主成分分析方法的熵权-主成分综合评价模型,运用该模型对我国四个直辖市及全国的生态承载力水平进行评价,发现全国及四个直辖市的生态承载力水平及影响因素,充分证明评价指标体系和评价模型的有效性和实践性,为区域生态承载力评价和城市生态发展提供一定的借鉴作用。

Based on the connotation and characteristics of ecological bearing capacity, the evaluation index system of regional ecological bearing capacity is constructed, and a comprehensive evaluation model of entropy weight and principal component based on entropy method and principal component analysis method is established. Using the model to evaluate the level of ecological bearing capacity of four municipalities and the whole country, we found out the level of ecological bearing capacity and its influencing factors, which fully proved the validity and practicality of the evaluation index system and evaluation model. It provides some reference for the evaluation of regional ecological bearing capacity and urban ecological development.
