摘要
济南长清区地质灾害发育较强烈,包括崩塌、滑坡、泥石流和岩溶塌陷等4种类型。该文在现状调查的基础上,采用"地质灾害综合危险性指数法",以地质、地形地貌、气候植被、地质灾害隐患点、地质灾害规模、分布密度、活动频次和险情等因素为评价因子,将长清区地质灾害易发程度划分为中易发区、低易发区及不易发区3个区,并在此基础上进行了防治分区划分,为地质灾害的预防和治理提供了科学依据。
Geological disasters strongly happened in Changqing district of Jinan city,including collapse, landslide,debris flow and karst collapse.Based on surveying information,adopting comprehensive geolog-ical disaster risk index method,choosing geology,landform,climate and vegetation,geological disasters, geological disaster points,scale,distribution density,activity frequency and risk factors as evaluation fac-tors,easy-happening degree of geological disasters in Changqing district can be divided into medium easy-happening area,low easy-happening area,and safe area.It will provide scientific basis for prevention and management of geological hazards.
