摘要
在地质灾害点分布图基础上,基于信息量模型,选定研究区地质灾害发育各影响因子及信息量值,据实际情况人为对信息量负值进行修正,同时利用ArcGIS的空间叠加分析完成研究区地质灾害易发性分区图。结果显示,易发性分区结果与野外实际调查情况相吻合,能在地质灾害风险评价中起重要参考作用。
On the basis of the geological hazard distribution map and the information quantity model,the influence factors and the information value of the geological disaster development in the study area are selected,and the negative value of the information is corrected according to the actual situation.At the same time,the geological disaster prone area map of the study area is completed by using the spatial superposition analysis of ArcGIS.The results show that the results of susceptibility zoning coincide with the field investigation,and can play an important reference role in the risk assessment of geological hazards.
