| 摘 要： | 结合主成分分析法和定性分析法研究武汉市2002—2008年生态用地面积变化的驱动因素。结果发现,研究中所选10个驱动因素均表现出与生态用地变化的显著相关性,并且均可归为一个主成分,即人类的需求。人类的需求决定着社会经济的发展,社会经济的发展又反过来制约着人类的需求,并共同导致生态用地面积和结构的变化。

| Abstract: | The change drivers of ecological land area of Wuhan City from 2002 to 2008 by the principal component analysis and qualitative analysis was explored in this paper.The results showed that the selected ten drivers and ecological land changes had shown significant correlation,and could be grouped into a main component,namely,human needs determines the social and economic development,social and economic development in turn restricts human needs,and commonly lead to change of areas and structure of ecological la... |
