Abstract：Anhui province is the transitional zone from subtropical region to temperate zone，where the transitional climate characteristics are pronounced. Anhui province is situated on the third step of east China，where the terrain is complex and the geomorphic type is parti-colored. In mountainous area，the bedrock is broken，and the cutting of terrain is intense，the trenches and vales are serried，which forms the geomorphic landscape of ravines and klints. In plain，the buttes，slopes and depressions terrain are salient. The Huaihe River and Changjiang River have many branches and lakes on their water-fronts. The pluralistic natural，geomorphic and geological conditions result in all kinds of exogenic geological disasters，as karst cave and karstic earth cave collapse，toppling，landslide，land subsidence，continual descent of groundwater level，water resources pollution，soil erosion，endemic diseases，washoutting of banks of rivers and lakes，and toppling of banks，etc. The development and distribution of disaster are conditioned by the regional environmental geological conditions，and effected by hydrology，human being’s engineering activities and economic activities. The carriers of disaster are rock，soil and water. These disasters damage the geological ecological environment which human being lies on，and seriously restrict the sustainable development of economy，society and environment. Based on the research on the characteristics of regional environmental geology and the composition and engineering property of rock and soil mass，beginning with the crossfeed action among human being’s economy，engineering activities and geological environment，the article approaches the action regularity of regional environmental geology，forecasts the generation and development trend of geological disaster. These are of important significance to retain geological ecological environment，reappear human being’s living environment in accord of human being and terra，and insure the sustainable development of the regional economy，society and environment.
