综合危险性指数法在东港区地质灾害易发区划分中的应用

The Method of Geo-hazards Susceptibility in Division Disaster-prone Areas of Donggang District

本文考虑了引发地质灾害发生的自然因素和人为因素,选用了影响地质灾害发生的地质条件、地形地貌条件、气候植被条件、人为条件、地质灾害规模、分布密度、活动频次、险情这8个因素作为地质灾害综合危险性指数法的评价因子,对东港区的地质灾害进行易发定量评价,将东港区划分为地质灾害高、中、低和非易发区四个等级。

In this paper, it has considered the natural factors and human factors Which caused the geological disasters, and selected eight factors of geological conditions, terrain conditions, weather conditions of vegetation, human conditions, geological disasters size, density, activity frequency, danger of geological disasters which affect the geological disasters. As evaluation factors of the method of Geo-hazards susceptibility to prone geological disasters quantitative evaluation in Donggang District, the eight factors divided Donggang District into four areas： high-prone areas, moderate-prone areas, sub-prone areas and none-prone areas.
