摘要
在充分收集、整理临沂地区地质成果的基础上,对该地区岩溶塌陷的形成条件及影响因素进行分析,确定对该地区岩溶塌陷形成机制和发育规律有影响的地质因素,采用层次分析方法(AHP)确定不同岩溶塌陷影响因子在发生岩溶塌陷中的权重,运用GIS数据管理与空间地理信息分析功能和融合技术,创建了基于GIS信息融合型岩溶塌陷的危险等级量化指数分区评价图,利用临沂地区发生的岩溶塌陷实际情况对该评价方法进行工程验证。
In fully collecting, sorting predecessors on the basis of existing research results, the formation of karst collapse conditions in linyiarea and influence factors were analyzed, the author determined development regularities of karst collapse in the region, the formation mechanism of factors have important influence to collapse.By adopting the method of analytic hierarchy process （AHP） to determine different karst collapse impact factor weights in karst collapse occurred ,and applied the powerful data management of GIS spatial analysis function ,Establishing GIS information fusion of karst collapse risk quantitative evaluation index partition method .andapplied this method for evaluation of karst collapse risk of linyi region
