生态城市可持续发展差异分析——以甘肃省14个市州为例

Difference Analysis on Ecological Cities of Sustainable Development

以甘肃省14个市州为研究对象,在生态城市和可持续发展理论的基础上,运用主成分分析方法和聚类分析方法,选取2007年甘肃省生态城市可持续发展指标因子36项,通过建立可持续发展生态城市的评价指标体系分析了甘肃省生态城市可持续发展水平。研究表明:通过主成分分析,甘肃省生态城市可持续发展存在着明显的地域差异,其影响因素可概括为综合经济发展因素、工业发展因素、土地利用因素、环境质量因素、基础设施因素、人口因素6个方面,其累积贡献率达到92.808%;通过Q型聚类分析,将甘肃省14个可持续发展生态城市划分为发达区、较发达区、欠发达区和落后区4种地域类型,并分别提出了相应的对策建议,为可持续发展生态城市提供了理论依据。

14 cities and prefectures were took as research objects, and the methods of principal component analysis and cluster analysis were applied, as well as 36 index factors of ecological cities of sustainable development in Gansu province were selected in 2007, the ecological cities of sustainable development in Gansu province was analyzed by building evaluation index system which based on the theories of ecological city and sustainable development. The results showed that：According to the principal components analysis, there were obvious region differences in ecological cities of sustainable development in Gansu province, and 6 factors of comprehensive economic development, industry development, land utilization, environmental quality, infrastructure and population were summarized, and the cumulative contribution rate could reach 92. 808%. According to the Q-type cluster analysis, 14 ecological cities of sustainable development in Gansu province were divided into 4 regional types such as developed region, more developed region, underdeveloped region and poor region, and some corresponding countermeasures and suggestions were put forward to provide the theoretical basis for constructing the ecological cities of sustainable development.
