【摘要】 在SPSS17.0及EXCEL2007软件平台的支持下,运用主成分分析法,基于生态位理论,从分析"美丽中国"生态位的概念及构成出发,系统构建了"美丽中国"生态位、生态位宽度及生态位空间分异评价模型,并以2002—2012年湖南省各设区市为例开展了实证研究。结果表明:基于生态位理论的"美丽中国"评价模型较其他评价模型更加系统全面;"美丽中国"生态位评价模型由3个子系统层、9个因子层及35个指标层构成;湖南省的"美丽中国"生态位及生态位宽度存在空间差异,东部地区大于中西部地区,变化趋势呈先增加后减小的特点,保护生态环境、发展生态经济是建设"美丽中国"的最佳选择。更多还原

【Abstract】 Supported by SPSS17.0 and EXCEL2007 software platform, used the principal component analysis, based on niche theory, from the analysis of the concept and structure of "beautiful China" niche, it build systematically the evaluation model of "beautiful China" niche、niche breadth and niche space differentiation, and carried out empirical research in all cities of Hunan province from 2002 to 2012 as an example. The results show that: the model of "beautiful China" evaluation system based on niche theory is more systematic than the others; it was constituted by three subsystem layers, nine factor layers and 35 index layers. The "beautiful China" niche and niche breadth of Hunan Province have spatial differences. It in eastern region is larger than in central and western regions. The characteristics of the changing trend increased at first and then decreased. Protecting the ecological environment and developing ecological economy is the best choice of building "beautiful China".更多还原
