摘　　要：利用GIS技术对庆元县山地灾害与地形、地貌、坡度和坡向作空间叠置分析结果表明:山地灾害发生密度,以高丘地形、凝灰岩低丘地貌、东南向缓坡最高;山地灾害绝对发生量,则以低山地形、凝灰岩低山地貌、东南向斜坡地段最大。By means of GIS, the relationship between the unanticipated water and soil disaster and topography was studied The result showed that the amount of disaster on low mountain area, tuff low mountain area and lean southeast facing aspect slope was the largest, however, it was high hill area, tuff low hill area and gentle southeast facing aspect slope that had the highest density of disaster
