摘　　要：本文对贵州石漠化的形成、地质背景以及出现的地貌类型进行了分析 ,并对贵州的石漠化划分为喀斯特洼地石漠化区 ,纯质石灰岩、白云岩组成的峰林、峰丛石漠化区 ,纯质石灰岩、白云岩缓坡山地、坟丘石漠化区 ,白云岩组成的砂质丘陵石漠化区与碳酸盐类岩层与非碳酸盐岩类岩层互层、间层石漠化 5种类型 ,对这 5种类型的特点进行了分析 ,并提出了相应的植被恢复模式。The formation, geological background and topography types of desertification in Guizhou province are analyzed. Five types of desertification are divided. They are the depression land desertification region, the stone forest and hill desertification region composed by pure limestone and dolomite, the gentle slope land and tomb desertitication region of pure limestone and dolomite, the sandy hill desertification region of dolomite and the Karst desertification region of carbonate rock interlaced with non-carbonate rocks. The features of five types are analyzed and their vegetation restoration models are presented in this paper.
