摘　　要：文章对淮河流域(江苏段)50年来所发生地质灾害进行总结。在地质灾害调查的基础上,从岩性、地形地貌、地质构造、降雨、人类活动等方面对区内发育的滑坡、崩塌、地面沉降、岩溶地面塌陷、采空地面塌陷等主要地质灾害类型进行了分析研究,得出淮河流域(江苏段)地质灾害发生的主因为人为活动,在其它适宜的条件如软弱层、构造、降雨等配合下形成了地质灾害的发育现状。在此基础上,提出以防为主,科学评估、加强监督与宣传的防治对策。The paper summarized the geological disasters in Huaihe River drainage area （in Jiangsu province） in the last 50 years. Based on geological disaster investigation, landslide, collapse, land subsidence, karst collapse and collapse by mined cavity in the area were analyzed from several aspects, such as lithology, topography and geomorphology, geological structure, rainfall and human activity etc. Human activity is the main cause of the geological disasters. The present development is not only effected by human activity, but also by other causes such as soft layer, geological structure and rainfall etc. The paper proposed a main countermeasure as putting prevention first, evaluating disaster scientifically and enforcing supervision and propaganda.
