基于生态压力指数法的内蒙古生态环境压力趋势研究

Study on Eco-environmental Stress Trend of Inner Mongolia Based on Ecological Stress Index

[目的]基于生态压力指数法,分析内蒙古生态环境压力的变化趋势。[方法]采用改进的生态压力指数(ESI)分析法,对1996～2009年内蒙古生态环境压力变化趋势和2008年内蒙古主要工业城市的生态环境压力进行了分析。[结果]1996～2009年,内蒙古经济发展对生态环境压力呈V字型变化,总体呈上升趋势,2003年以来更为显著,其中环境污染分指数急剧上升;2008年内蒙古大多数城市生态环境压力较小,但呈两极分化态势,包头、乌海、呼和浩特偏向资源能源消耗,鄂尔多斯、赤峰偏向环境污染。[结论]该研究为内蒙古生态环境的保护和产业结构的调整提供了科学依据。

[ Objective ] The study aimed to analyze the trend of eco-environmental stress in Inner Mongolia using ecological stress index method. [ Method ] On the basis of improved ecological stress index （ESI） analysis method,the trend of eco-environmental stress in Inner Mongolia from 1996 to 2009 was analyzed ,as well as the changes of eco-environmental stress in major industrial cities of Inner Mongolia in 2008. [ Result] With the economic development of Inner Mongolia from 1996 to 2009 ,the U-shape change could be found in the eco-environment stress, showing an upward trend on the whole, especially since 2003, and there was a sharp raise of the environmental pollution index. In addition, the eco-environmental stress lessened in most cities of Inner Mongolian in 2008, but it was in a polarization state, that is, Baotou, Wuhai, Hohhot biased resource and energy consumption ,while Erdos and Chifeng biased environmental pollution. [ Conclusion] The research could provide scientific references for the protection of ecological environment and the adjustment of industrial structure in Inner Mongolia.
