摘　　要：对地质灾害进行评价可以为地质灾害的防治和管理提供重要依据。本文在介绍地质灾害易发区划分原则的基础上,将研究区划分为网格单元,对各网格单元逐个提取各项评价指标,并计算地质灾害易发程度指数,进而根据地质灾害易发程度等值线划分易发区。结果表明:全区共有高易发区2个、中易发区62个、低易发区5个、不易发区9个。最后对地质灾害易发区进行了分区评价。The evaluation of geological disasters can provide an important basis for the prevention and management of geological disasters.Based on the introduction of the division principle of geological disaster susceptibility areas,the study area is divided into grid units,and the evaluation indexes of each grid unit are extracted one by one,and so the susceptibility index of geological disaster is calculated,and further the different areas are divided according to the contour of the susceptibility index of geological disaster.The research reveals that:there are 2 high-risk areas,62 medium-risk areas,5 low-risk areas and 9 no-risk areas.Finally,the assessment is put forward to different divisions of geological disasters.
