中原经济区主体城市群生态宜居评价与构建策略

根据中原经济区主体城市群节点城市的发展状况，按照聚类分析原理，运用聚类分析法、相关系数法、极大不相关法和征询专家意见法，选取自然生态相与人文生态相中的27个因子，构建生态宜居评价体系。引用熵值理论，采用物元分析法，联系模糊集与欧氏贴近度，建立熵权模糊物元评价模型，对中原经济区主体城市群生态宜居进行分析评价。结果显示：中原经济区主体城市群生态宜居整体水平为中等偏好，提升空间很大；群域内各节点城市发展不均衡，生态宜居水平差别较大，其中，郑州最好，济源、新乡、漯河、许昌次之，焦作、洛阳、开封、平顶山较差。并结合实际，提出了进一步加强中原经济区主体城市群生态宜居建设的对策和建议。

Research on the Livability Assessment for the City Agglomeration in Central Plains Economic Zone

In accordance with the development of the node cities from the main urban agglomeration in Central Plains Economic Zone and the principle of cluster analysis, this paper selected 27 factors from the natural ecology and humanities ecology, built the ecological livability evaluation system by using cluster analysis, correlation coefficient method, non - correlational method and by obtaining experts＇ advice. With the use of entropy theory and matter - element analysis theory, this paper contacted fuzzy set with euclidean approach degree, established entropy weight fuzzy element model and gave full analysis and evaluation to the ecological livability of the main urban agglomeration in Central Plains Economic Zone. The results showed that the overall level of the ecological livability of the main urban agglomeration in Central Plains Economic Zone is moderate preference and there is much room for improvement. The ecological livability of the node cities showed uneven development among these cities, Zhengzhou is the best, Jiyuan, Xinxiang, Luohe, Xuchang followed, while Jiaozuo and Luoyang, Kaifeng, Pingdingshan are left behind. This paper also proposed countermeasures and suggestions to further strengthen the ecological livability of the main urban agglomeration in Central Plains Economic Zone.
