中文摘要:

利用云贵高原2000年、2010年和2018年的遥感影像及气象数据,并结合生态系统弹性力计算方法,对云贵高原生态系统弹性力进行计算,分析了云贵高原25个市生态系统弹性力的时空分布特征,同时对其变化的主要影响因素进行探究。结果表明:云贵高原生态系统弹性力在研究期内呈现逐年增加趋势;在空间上,云贵高原生态系统弹性力分布为西南高、西北低、中部局部较低,东部较高。将生态系统弹性力分为4个等级,其中较弱和中等等级面积占比呈减少趋势,较强和很强等级面积占比逐年增加。驱动因子分析表明,降雨和气温是影响生态系统弹性力空间分布变化的主要因素。研究结果可对云贵高原生态系统保护提供一定的科学依据。

英文摘要:

Using the remote sensing images and meteorological data of the Yunnan-Guizhou Plateau in 2000,2010 and 2018 and combining with the calculation method of ecosystem resilience,the ecosystem resilience of the Yunnan-Guizhou Plateau was calculated,the spatial and temporal distribution characteristics of the ecosystem resilience in 25 cities of the Yunnan-Guizhou Plateau were analyzed.,and the main influencing factors of its changes were also explored.The results showed that the ecosystem resilience of the Yunnan-Guizhou Plateau increased steadily from 2000 to 2018,indicating that the self-regulation and anti-disturbance capabilities of the ecosystem in this region were continuously enhanced.Spatially,the distribution of ecosystem resilience in the Yunnan-Guizhou Plateau was high in the southwest,low in the northwest,relatively lower in the middle,and relatively higher in the eastern.The ecosystem resilience was divided into four grades,among which the proportion of weak and medium grades showed a decreasing trend;the proportion of strong and very strong grades increased year by year.The driving factor analysis showed that rainfall and temperature were the main factors affecting the spatial distribution of ecosystem resilience.The results can provide a certain scientific basis for ecosystem protection in the Yunnan-Guizhou Plateau.
