| 摘 要： | 针对地质灾害危险性定量评价存在的问题,以山西省绛县地质灾害危险性评价为例,依据研究区地质灾害特点,在地理信息系统基础上尝试运用趋势面分析法对地质灾害危险性评价进行了研究。结果表明,用该方法得出的结果与研究区地质灾害实际情况相符合。说明运用趋势面分析法对地质灾害危险性评价是可行的,可为解决地质灾害危险性区划提供新的理论方法。

| Abstract: | Focusing on the problems in quantitative evaluation of geological disasters,we investigated and discussed the risk assessment system of geologic disasters by using the tendency analysis method in GIS program.The risk assessment of Jiangxian County in Shanxi Province was taken as the study case.The results of this method agreed well with the actual geological survey information,which implies that the tendency analysis is applicable for risk assessment.This paper provides a new theoretical method for geological disaster zoning. |
