| 摘 要： | 以岱山县衢山镇为研究区,以斜坡单元为评价单元,在重点分析地质环境条件与地质灾害相关性的基础上,筛选影响地质灾害易发性的主要参评因子,构建评价模型,并完成指标因子的分析与量化,并借助层次分析法和综合危险指数法确定易发性的综合评分,进而划定易发程度等级和修编易发程度分区。评价模型的构建过程可为海岛地区地质灾害易发性评价提供参考。

| Abstract: | In this paper,taking Qushan town of Daishan county as the research area and the slope unit as the evaluation unit,basing on emphatically analyzing the correlation between geological environment conditions and geological hazards,we screen the main factors that affect the susceptibility of geological hazards,and construct the evaluation model to analyze and quantifies index factors.Further,we determine the comprehensive grading of susceptibility by the methods of analytic hierarchy process and comprehensive risk index.Lastly,the susceptibility level is delimited and the partition of susceptibility zones is modified.The construction of the evaluation model can provide a reference for evaluation of geological hazard susceptibility in island areas. |
