山东泰安市地质灾害易发性分区

Geology hazard's susceptibility zonation in villages and towns in Tai'an,Shandong province

本文通过对研究区内地质灾害的系统调查与分析,针对不同地质灾害类型选取不同评价因子,利用MAPGIS空间分析功能,计算地质灾害危险性综合指数,并根据其危害程度将全区划分为高易发、中易发、低易发和不易发四个级别;最后针对不同易发程度和不同地质灾害类型,提出防治对策和措施,为土地利用总体规划修编、地质灾害防治提供针对性和操作性更强的科学依据。

On the basis of investigations and analysis of the disasters in the area,different evaluation factors were selected according to different geological disaster types; then,spatial analysis function of MAPGIS was used in calculating the geological hazard index; thirdly,according to the harm degree of different disaster,the whole research area was divided into four classes： high,moderate,low,and non-susceptibility areas; At last,variable control measures were proposed,thus to provide operational and applicable basis for overall land using planning and for geological disaster to prevention and treatment.
