【摘要】：针对城市发展过程中出现的问题,深入分析了生态城市的内涵,结合DPSIR模型,从经济水平、环境问题、社会问题、城市现状以及政府控制等方面给出了构建生态城市指标体系的逻辑框架.面对数量众多的评价指标,提出了一种兼顾指标的"重要性"、"相关性"和"区分度"等多个因素的指标筛选方法.主要运用德尔菲方法、改进的熵值法及Person相关系数法对核心指标进行筛选,并进一步通过指标信息贡献率这一度量标准反映指标构建的合理性.最后,以辽宁省8个主要城市为例,验证了指标筛选方法的有效性.
[Abstract]:In view of the problems in the process of urban development, the connotation of eco-city is deeply analyzed, and combined with DPSIR model, from the economic level, environmental problems, social problems. This paper gives the logical frame of constructing the ecological city index system in the aspects of the present situation of the city and the government control, and puts forward a kind of "importance" of taking into account the index in the face of a large number of evaluation indexes. The methods of "correlation" and "degree of distinction" were used to screen the core indexes. The Delphi method, the improved entropy method and the Person correlation coefficient method were mainly used to screen the core indicators. Furthermore, the contribution rate of index information is used to reflect the rationality of index construction. Finally, the validity of the index selection method is verified by taking 8 major cities in Liaoning Province as an example.
