【摘要】 全国地质灾害易发区区划主要依据地形地貌、岩土体类型及性质、地质构造和水文地质条件等地质环境背景条件,地质灾害的类型、发生发展的时空规律及发展趋势,结合大气降水、人类活动强度等动力条件,对全国地质灾害易发程度进行宏观区划。通过对已发生滑坡崩塌、泥石流、地面塌陷、地面沉降和地裂缝的地质环境特征的总结,分析各种地质灾害发生的典型特征,也就是易发特征。采用定性与定量相结合的工程地质类比原理,进行主要地质灾害类型易发程度区划。在此基础上,编制了全国滑坡崩塌易发区图,全国泥石流易发区图,全国地面塌陷易发区图,全国地面沉降和地裂缝易发区图。把全国分成滑坡崩塌高易发区8个,中易发区8个;泥石流高易发区8个,中易发区9个;地面塌陷高易发区5个,中易发区6个;地面沉降和地裂缝高易发区3个,中易发区5个。更多还原

【Abstract】 The zonation of geo-hazard susceptivities bases mainly on background conditions(such as the geomorphology,rock and soil type and their property,structural geology,hydrology conditions),the type,spatio-temporal properties and trends of geo-hazards,and precipitation,man-activities.On the basis of summarization of occurred geohazards,such as landslide,debris flow,surface collapse,ground subsidence and ground fissure,we studied the rule(susceptivity) of each type.Using the analogy law of engineering geology,we zone each type of geo-hazard,and produced the susceptivity maps of landslide,debris flow,surface collapse,ground subsidence and ground fissure of China,respectively.We get 8 landslide high susceptivity areas,8 middle landslide susceptivity areas;8 high debris flow susceptivity areas,9 middle debris flow susceptivity areas;5 high surface collapse susceptivity areas,6 middle surface collapse areas;3 high ground subsidence and ground fissure susceptivity areas,5 middle ground subsidence and ground fissure susceptivity areas.更多还原
