摘　　要：人口超载与环境退化的关系密不可分,对于地处喀斯特地区,且人多地少、人地矛盾突出、生态环境极其脆弱的贵州省而言,人口密度与人类活动强度是喀斯特地区石漠化及一系列环境退化的重要驱动因素。通过利用在GIS、RS技术手段支持下的地理空间数据,结合当地人口数据,对贵州省2000年至2010年近十年间环境退化的空间格局和变化进行了时空叠加综合分析,结果显示出近十年贵州省环境退化与人口超载的格局及变化趋势,并且通过深入的时空对比,发现研究区具有低等级退化主要由自然环境背景要素驱动、高等级退化主要由人口因素催生的环境演化分化特征。Overpopulation is closely related to environment degradation, especially for Guizhou, a province with large population, limited farmland and fragile ecological environment. Using GIS/RS-based geographical data and population data, we analyzed the spatial and temporal change of environment degradation in Guizhou from 2000 to 2010. The results revealed that lower-level degradation was mainly caused by natural factors, while higher-level degradation was mainly driven by population and their intense activities.
