济南市生态弹性力评价研究

Evaluation on city ecosystem resilience in Jinan City

城市生态弹性力是指城市生态系统的自我维持、自我调节及其抵抗外界各种压力和扰动能力的大小,是城市生态承载力研究的基础。以济南市为研究对象,采用主成分分析法,对济南市生态弹性力现状进行了综合评价。结果表明:2000—2011年间,济南市的生态弹性力虽有所波动,但总体呈现上升趋势,生态弹性力指数由2000年的–0.45增至2011年的0.26,表明济南市的生态环境质量得到很大改善。论文最后根据生态弹性力的影响因素提出了提高生态弹性力的相关治理对策。

City ecosystem resilience refers to the size of city ecosystem＇s capacity of the self-maintenance, the self-adjustment, and the ability of resistance to the external pressures and disturbance. R is the basis of the research about the city ecological carrying capacity. This paper evaluates on Jinan City ecosystem resilience synthetically using the principal components analysis method. The results show that the Jinan City ecosystem resilience is fluctuating, but it shows increasing trend generally. The city ecological resilience index increased from -0.45 to 0.26 during 2000 to 2011, which indicates great improvement in the ecological environment quality in Jinan City.
