摘要
利用ArcGIS Living Atlas of the World,基于“木里藏族自治县3.28森林火灾”受灾区域的地形、降雨量和植被等资料,采用GIS技术和加权综合法,对研究区域的山体滑坡敏感性进行分析评价。结果发现,研究区以中高风险区为主,占整个研究区总面积的71%,是发生山体滑坡风险的主体部分。高风险区域有两条道路经过,需要重点防范。通过使用Living Atlas数据来查找森林火灾过火区域内绿色植被较少、坡度较高和降雨水平较高的区域,可以有效地节省人力物力,并实现长期快速检测。
Based on the ArcGIS Living Atlas of the World, and taking the topography, rainfall, and vegetation data of the affected area of the 3.28 forest fire in Muli Tibetan Autonomous County as the basic data, the weighted synthesis method was applied to analysis and evaluation the landslide sensitivity of the study area using GIS technology. The results show that the study area is dominated by medium and high risk areas, which account for 71% of the total study area and are the main part of the landslide risk. The high-risk area has two roads passing through it and needs to be focused on prevention. Using Living Atlas data to locate areas with less green vegetation, higher slopes, and higher rainfall levels within the forest fire overfire area would effectively save labor and resources and enable rapid detection over time.
