| 摘 要： | 依据生态弹性力的概念,构建了北京市生态弹性力的指标体系,并利用SPSS软件确定各指标的权重,分析和评价了2001—2008年该地区生态弹性力的发展状况。结果显示:生态弹性力指数在研究时段呈现较大波动,但整体呈现逐渐增大的趋势。2001—2003年呈下降趋势,指数由-0.248降至-0.976;2004—2008年指数明显上升,由0.071增至1.047,其中2006年波动较大为-0.261;结果表明在多项措施的实施下,北京市的生态环境质量得到了逐步改善。

| Abstract: | The index system for ecosystem resilience in Beijing City was established according to the definition of ecosystem resilience.The weight of each index was calculated by software SPSS.The developing trend of ecosystem resilience from 2001 to 2008 was analyzed and assessed.Result indicated that the exponential of ecosystem resilience revealed obvious fluctuations in the study period,but it exhibited an increasing trend on the whole.During 2001-2003,the exponential decreased from-0.248 to-0.976,while it increa... |
