文章摘要：采用主分量分析评估模型法,对西部生态脆弱区的资源型城市鄂尔多斯市在2003-2011年时间序列内的城市生态环境影响进行了评价与分析。结果表明：鄂尔多斯城市生态系统整体处于不稳定的发展状态,其中生态质量子系统的发展水平一直处于稳步上升、逐步改善的趋势;环境质量子系统的发展水平呈现出先下降、再上升、再下降的整体下降趋势;环境治理子系统的发展水平总体处于稳步上升、中间略有波动的趋势;综合来看,鄂尔多斯城市生态环境影响的总发展水平处于整体上升、中间略有波动的状态。

Abstr：City is an artificial and natural composite system. Economy,environment and society systems of a city have a relation of mutual influence and resonance. Ecosystem of a resource-based city is more vulnerable than that of an ordinary city and has obvious complexity,fragility,ecological sensitivity and heterogeneity. With Erdos City,Inner Mongolia,China as an example in ecological fragile region,the paper used a principal component analysis evaluation model,and SAS software to assess the city ecological environment impact in the period of 2003-2011.Understanding the ecological situation in Erdos City,and the establishment of safety regulation of city ecological environment management system. The results showed that the overall Erdos City ecological system is in an unstable state of development. The development level of ecological quality sub-system has been rising steadily and has a gradually improving trend. The maximum value is 1.273 6 in 2011. The minimum is-0.821 6 in 2003. The difference is 2.095 2 between the maximum and minimum. The development level of environmental quality sub-system presents a tendency of declining firstly,and then increasing,and last decreasing. The minimum is 0.247 3 in 2006.The maximum value is 1.172 5 in 2003. The difference is 0.925 2 between the maximum and minimum. The level of development of environmental management sub-system is steadily increasing with slightly fluctuation. The maximum value is 1.512 in 2010. The minimum value is 0.173 in 2003. The difference is 1.339 between the maximum and minimum. In general,the total development level of Erdos City ecological environment influence is in a rising and with slight fluctuation state. The main reason is that the per capita public
