| 摘 要： | 为了评价地质灾害的危害程度,提出了地质灾害危害性概念,选择历史灾害危险性、潜在灾害危险性、社会经济水平、承灾体类型4个基本要素和相应的17个评价因子作为评价因素,利用二级模糊综合评价方法,对吉林省东部山区地质灾害危害性进行分区评价.评价结果为:在中低山区和低山丘陵区两个不同地貌单元的地质灾害区中,划分出7个不同级别的危害性亚区.高危害区主要分布于通化、白山地区,鸭绿江上游和延吉盆地区,是今后地质灾害防治的重点区域.

| Abstract: | The perniciousness of geological disaster is used to evaluate the danger degree of geological disaster. Divided region evaluation of perniciousness of geological disaster of mountainous area in east Jilin Province, was done by means of secondary fuzzy and synthetical evaluation method by selecting four basic factors such as harmfulness of historical disaster, harmfulness of latent disaster, level of social economy and type of bodies to undertake disaster and 17 relevant estimate factors to act as evaluating factors. Evaluating results as follows: 7 different level subregion of harmfulness are marked off in the area of geological disaster of two different topographical feature unitsmiddle and low mountainous area and low hill area. High perniciousness area are mainly situated in Tonghua , Baishan , upriver of Yalu and Yanji basin which are the important areas for prevention and cure of geological disaster in the future. |
