南疆铁路沿线地区城市化与生态环境质量相关性分析

以1997—2008年南疆铁路沿线地区统计资料和调查数据为数据源,在利用主成分分析法与层次分析法对南疆铁路沿线地区城市化综合水平与生态环境综合质量进行测度的基础上,对城市化综合水平指数与生态环境综合指数之间关系进行了相关性分析。研究表明,南疆铁路沿线地区城市化综合指数总体上呈现出增长趋势,表示南疆铁路沿线地区进入城市化快速发展时期；而生态环境综合质量随着城市化发展呈现出波动性的变化特征,1997—2004年生态环境综合指数具有增长趋势,但从2004年起生态环境综合指数有所下降,生态环境质量开始恶化。南疆铁路沿线地区城市化综合水平的提高是产生生态环境变化的主要因素之一。

Correlation between Urbanization and Ecological Environment in Areas along South Xinjiang Railroad

Based on the statistical information and field survey data in 1993—2008 and by making use of the principal component analysis and hierarchical synthesis methods, the correlation between urbanization level and ecological environment quality in areas along south Xinjiang Railroad is analyzed through calculation of comprehensive urbanization index and comprehensive index of ecological environment. The comprehensive urbanization index of the areas increased generally and the present urbanization level already got into rapid development stage. The comprehensive index of ecological environment of the areas fluctuated generally, and the index increased during 1997—2004, decreased after 2004, indicating the deterioration of ecological environment. The increase of the comprehensive urbanization level in areas along south Xinjiang Railroad was one main factor causing environmental change.
