| 摘 要： | 采用G IS技术对三峡库区云阳-巫山段的滑坡坡形进行量化采集,获得5类坡形模型。利用贡献率法,对坡形与滑坡发育、坡形与地层关系的贡献率分析,得出Ⅳ型坡对滑坡发育的贡献率高;Ⅲ型坡、Ⅴ型坡对滑坡发育的贡献率中等;Ⅱ型坡、Ⅰ型坡对滑坡发育的贡献率低。

| Abstract: | This paper focuses on contributing ratios of the slope shape towards the landslide development.The slope shape data of landslides from the Yunyang to Wushan segment of the Three Gorges Reservoir area is analyzed with GIS information statistical methodologies.Five slope shape models were obtained.The contributing ratio is computed by dividing the contributing index of slope shape with the total contributing index of slope shape.It was concluded that the model IV contributes most to landslide development;models III and V contribute moderately;and models I & II contribute little to landslide development. |
