There is a great difference between the distribution and evolvement characteristics of slope geological hazard in the same geographical location and climatic conditions，taking the similar structural-genetic connection in Wudongde reservoir area of Jinshajiang River valley for example． In all engineering geological conditions， the chronologic age and attitude of strata，and the lithologic association factors control the distributions and evolvement characteristics of slope geological hazard in the studied area． The study shows that the slopes in geological evolution are in different stages． The conclusion helps to understand the types and the intensity of geological disasters．
