本文提出了中国地质灾害的空间分类和成因分类系统,并根据13类常见的地质灾害组合类型进行了区划,基本上反映了我国高原、山地、内陆盆地、平原及滨海地区地质灾害的地带性和地区性分布规律,以小比例尺图显示了中国地质灾害的类型与分布。该图共划分为11个地质灾害区。在此基础上初步论述了1949—1990年间我国崩塌、滑坡、泥石流灾害的主要受灾地区和受灾损失。最后,根据当前形势,提出了减灾、防灾的对策意见和建议。

Spatial classification and genetic classification systems of geohazards in China arc presented, and their zonation is carried out with respect to the 13 Common associations of geohazards, Which esse-ntially reflects the distribution characteristics of geohatards in plateaus, mountains, basins,plains and coa-stal regions. The geohazard-caused losses during 1949-1990 are analysed and some mitigatimg measure-meats are suggested.
