摘　　要：分析了辽宁省鞍山市的地质环境条件以及降雨与地质灾害的关系,在综合考虑地形、地貌、植被覆盖等因素的情况下,以乡镇为研究单元,采用了网格剖分单元,利用BP神经网络算法对研究区进行了地质灾害危险性评价。最后,基于ArcGIS二次开发搭建了集灾害易发性、危险性分区统计,危险区划评价,预警分析模型生成等功能于一体的预警分析系统。应用该系统对辽宁省鞍山市地质危险性进行评价,并取得了较好的成果。This paper analyzes the relationship of geological conditions,rainfall and geological disasters in Anshan of Liaoning Province,in comprehensive consideration of factors such as topography,landform,vegetation coverage,With the township as the research unit,the grid subdivision unit is adopted,and the BP neural network algorithm is used to evaluate the geological hazards in the research area.Finally,based on the ArcGIS secondary development builds the early-warning analysis system of disaster vulnerability,danger zone statistics,risk zoning evaluation,early warning analysis model generation and other functions..This system is used to evaluate the geological hazard in Anshan City of Liaoning Province and has achieved good results.
