基于ArcGIS可视化建模方式的区域滑坡危险性评价

摘要

滑坡危险性评价是滑坡灾害防治的重要前提和基础,简单高效的评价方式是其中的一个研究重点。本文以四川安县作为研究区域,基于ArcGIS中的分析功能,引入可视化的建模工具Modelbuilder,以模型的方式演示和运行整个滑坡危险性评价过程,得到了滑坡危险性的分级图,并进行对比分析。实验结果表明,利用可视化建模方式完成复杂地区的滑坡危险性评价,能够简化操作流程,节约时间和精力。%The landslide hazard assessment is the important content of landslide research and the foundation of landslide prevention.How to implement the high-efficient evaluation is very important.Based on the Modelbuilder module of ArcGIS software,this paper firstly discussed the process of visual modeling for landslide hazard assessment.Then six evaluation factors were determined to design the landslide hazard assessment model.Finally,an experiment of the landslide hazard assessment model was implemented in the case study area of Anxian County,Sichuan province.The results prove that the scheme addressed in the paper is effective and feasible.
