广西喀斯特地区生态环境脆弱,植被退化严重,石漠化问题突出。随着一系列生态保护与建设措施的实施,广西植被已逐渐恢复,石漠化面积扩张趋势已得到控制。深入了解广西植被覆盖演变特征及其主导因素可为新一轮石漠化治理工程实施提供科学依据。本研究基于1982—2015年GIMMS NDVI3g生长季NDVI （the growing season GSN）数据和1982—2016年AVHRR VCF数据,分析广西植被时空变化特征,同时结合气候、土壤以及人类活动等因素,运用地理探测器模型,探究自然和人文因素对区域尺度植被覆盖变化影响的空间差异。结果表明,1982—2015年广西植被,尤其是林地面积比例呈增加趋势,裸地面积比例呈减少趋势;广西北...

Karst areas in Guangxi are typically eco-fragile zones, with serious degraded vegetation and rocky desertification. The vegetation in karst areas of Guangxi has been gradually recovering and the expansion trend of rocky desertification has been improving with a series of ecological conservation and restoration programmes. It is critical to explore the evolution characteristics and driving factors of vegetation recovery changes in Guangxi for the further implementation of rocky desertification treatment project. This study aimed to identify the spatial and temporal changes of vegetation in Guan...
