摘　　要：湖南是我国地质灾害的高发区,地形地貌类型复杂多样。利用以往的资料、野外调查及G IS技术,结合湖南省地貌图,对湖南主要地质灾害进行分析,绘出灾害点分布图。结果表明:湖南主要地质灾害集中分布于湘西北、湘西、湘南和湘东地区;与低山、低中山、中中山和喀斯特山原等地貌类型关系密切。Hunan is one of the provinces in China suffering from serious geological hazards, where geographic types are various and complicated. By means of existing data, field investigation, GIS and geomorphological map of Hunan, the main geological hazards in Hunan are studied and a distribution of geological hazards is mapped. The results show that main geological hazards mainly distribute in the northwestern, western, southern and eastern regions in Hunan. The geological hazards are closely related with the geographic types as low mountain, medium low mountain, midmedium mountain areas and karst plateau area
