济南市长清区地质灾害易发程度评价及防治分区划分

Comprehensive Evaluation on Easy-happening Degree of Geological Disasters and Prevention Zoning in Changqing District of Jinan City

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。

Abstract:

Geological disasters strongly happened in Changqing district of Jinan city, including collapse, landslide, debris flow and karst collapse. Based on surveying information, adopting comprehensive geological 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 factors, 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.
