| 摘 要： | 采用GIS信息量统计法和叠加统计法对三峡库区云阳一巫山段地层因素对滑坡的贡献进行了分析，结果表明有3种地层对滑坡发育的贡献率最高，它们是区内主要滑坡发育地层。贡献率法定量分析各地层在滑坡发育中的不同贡献作用，为区域滑坡成因研究提供了一种新的分析方法。采用这种新方法，可以克服传统方法的不足，使分析结果更为可靠，

| Abstract: | The contribution rate of stratum to landslide growth of Yunyang-Wushan segment in Three Gorges reservoir region is analyzed by statistical information method of GIS and statistical overlaying method. The result indicates that three kinds of strata make contribution to the landslide among 20 kinds of strata. The presented method can be used to quantitatively analyze different effect of different strata on landslide growth, and new analysis method is offered for formation research of regional landslide. By using the new method, the shortage of traditional methods is overcomed, and the analysis result will be more reliable. |
