摘要
通过对研究区恩施市龙凤镇主要地质灾害现象实地调查和相应的资料收集,确定研究区地质灾害的危险性、易损性评价因子及因子权重,依据地质灾害风险评价原理,借助GIS数据处理平台,完成研究区地质灾害的风险评价工作。评价成果与实地调查资料基本一致,表明本次研究所采用的评价方法及数据处理手段是合理的,本次研究成果可作为研究区的地质灾害风险预测和防灾减灾管理工作的参考依据。
Based on the field investigation and data collection of geological hazards in the study area,the evaluation factors about hazard and vulnerability of geological hazards and factor weights are determined.And then the risk assessment of geological hazard in the study area is completed,with the help of GIS data processing platform,according to the principle of geological hazard risk assessment.The evaluation results are consistent with the field survey data,which indicates that the evaluation methods and data processing methods used in the study are reasonable.The results of this study can be used as a reference for the prediction of geological hazards and the management of disaster prevention of the study area.
