基于因子分析和聚类分析的生态环境质量评价

Study on eco-environment quality assessment based on factor and clustering analysis

从当前生态环境研究现状出发,采用因子分析法对影响生态环境质量的所有因素进行主成分分析及贡献大小评价、合成综合得分评估,同时利用聚类分析方法,对综合得分进行分类比较研究,确定生态环境质量的评价等级,为区域生态环境保护和规划治理提供依据.

This paper discusses current research of eco-environment quality assessment. By introducing factor analysis method to analyze principal component, evaluate variance and gain component scores for all the factors of each village and town. Carries out clustering analysis to classify component scores in order to define evaluation grading of ecological environment quality. The analytical results provides basis for protection and planning of regional eco-environment.
