| 摘 要： | 结合海南省保亭县1：5万地质灾害详细调查项目，根据野外实际调查与遥感成果，选取地质构造、地形地貌及人类活动3个大类，构造、工程地质岩组、坡度、坡高、海拔高度、植被覆盖率、河流及公路等8个小类作为地质灾害影响评价因子.在ArcGIS平台上运用AHP法，进行评价因子权重计算并建立评价模型，完成保亭县地质灾害易发程度区划，划分出高、中、低易发区，可为今后地质灾害预测与防治提供科学依据.

| Abstract: | Based on the detailed investigation of geological hazards in Baoting County,Hainan Province,with field survey and remote sensing results,this paper selects three items,i.e.geological structure,topography and human activities,including structure,rock assemblage,slope,altitude,vegetation,river and road,as the impact factors to evaluate the geological hazards.An assessment model for the probable occurrence level of geological hazards is established by analytical hierarchy process (AHP) the ArcGIS platform.Finally,the zoning of probable occurrence levels of geological hazards in Baoting County is completed with high-,medium-and low-probability areas.The result will provide scientific reference for geological hazard prediction and prevention in the future. |
