【摘要】 生态系统弹性是衡量区域生态系统健康和承载力的重要指标。基于生态系统弹性强度系数和生态系统弹性限度系数构建了生态系统弹性力综合评价模型,并运用标准差距平法对计算结果进行分级,对贵阳市区2000、2005、2010和2015年的生态系统弹性时空演变进行定量研究。结果表明:(1)贵阳市区的生态系统弹性力分级占比较大的主要为较强、中等和较弱,占总面积的95%左右,其余为很弱和很强的区域,占比约5%;(2)贵阳市区的生态系统弹性力在2000～2015年大体呈波动减弱态势,其中弹性力分级为较弱和很弱的区域分别增长3.24%和1.12%,而较强的区域则减少2.60%;(3)但弹性力很强的地区面积增加0.83%,部分区域的生态系统弹性力有所增强。更多还原

【Abstract】 Ecosystem resilience is an important index to measure the health of regional ecosystem.Based on the resilient force coefficient of ecosystem and the limit coefficient of ecosystem resilience, the comprehensive evaluation model of ecosystem resilience is constructed, and the calculation results are classified by the standard gap leveling method.and the spatio-temporal evolution of ecological system resilience in 2000, 2005, 2010 and 2015 in Guiyang was quantitatively studied.The results showed that:(1) The resilience of the ecosystem in Guiyang City was mainly relatively-strong, medium and relatively-weak, accounting for about 95% of the total area, and the rest was very weak and strong, accounting for about 5%.(2) The resilience of the ecosystem in Guiyang City was weakened by fluctuation from 2000 to 2015, and the resilience was classified as weak and relatively-weak areas grew by 3.24% and 1.12% respectively, while the stronger areas decreased by 2.60%.(3) But the area with strong resilience increased by 0.83%, and the resilience of ecosystems in some areas increased.更多还原
