我国30个大中城市生态文明建设评价

Discussion on ecological civilization construction of 30 large and medium-sized cities of China

在综合国力迅速发展的今天,生态文明建设问题受到了越来越多的关注,生态文明的健康良好运行被认为是一个国家逐渐变得强大的前提。因此构建生态文明评价体系并以此指导生态文明建设日益重要。构建生态文明建设评估指标体系,是评价我国生态文明建设的重要研究方法。本文基于我国30个大中城市2015年的数据,构建了一个生态文明建设评估指标体系。通过运用层次分析法和yaahp软件构建层次结构模型,并选取权重排序在前的10个指标,对其进行因子分析综合评价,并根据综合得分得出各个城市排名情况。同时,运用系统聚类分析方法得出聚类图,将各个城市划分为不同的类别并给出相应建议。

Ecological civilization is receiving more and more attention as the nation is advancing remarkably in many aspects in the world today,and it is widely believed healthy and well-functioned ecological civilization is a prerequisite of growing into a great nation.Therefore it is of growing importance to build an evaluation system and to guide the construction of ecological civilization.The setup of an evaluation index system is a critical methodology of evaluating the nation of ecological civilization buildup process.In this paper,we build an ecological civilization evaluation index system,which is based on data of year 2015 of 30 cities of China.We build a hierarchical model with stratified analysis and the yaahp software,and then do a principal component analysis（PCA） of the 10 most weighted factors to come up with a ranking list of those cities.Meanwhile,we using cluster analysis to get the cluster map of these cities,and offer our suggestions based the resulted clusters.
