摘要
为了分析延边地区山体滑坡的敏感性,采用人工神经网络方法,计算了坡度、坡向、土壤类型、地质类型和土地五个影响山体滑坡发生因子的权重值,并使用GIS加权叠加方法,得到了敏感性地图,最后,山体滑坡敏感性地图表明非常危险区域(0.9或以上)主要分布在坡度为25°~40°的山区。
In order to analyze the landslide susceptibility in Yanbian area,the paper adopts the artificial neutral network,calculates the weighted value of the five factors including gradient,slope aspect,soil type,geological type,and land which affect the mountainous landslides,adopts the GIS and weighted method to achieve the susceptibility map,and indicates the map can identify the most hazardous areas（ 0. 9 or above） mainly distribute in the mountainous areas of 25° ~ 40°.
