中文摘要三峡水库区滑坡发育与多种因素相关。这些影响因素可以归纳为两大类:外部因子和内部因子。其中斜坡相对高差是滑坡发育的必要内部条件之一,对斜坡的发育有着重要的影响。文章借助于GIS技术,采用贡献率法重点研究斜坡高差对研究区滑坡发育的贡献。通过对研究区内已有的205个滑坡样本点进行细致剖析,结果表明相对高差在500~1000m的斜坡对滑坡贡献率最高,是滑坡发育的主要高差区间;400m、1100~1300m斜坡贡献率中等,是滑坡发育的次要高差区间;100~300m、1400~1700m斜坡的贡献率较低,是滑坡发育相对较弱的高差区间。文章运用贡献率法定量地分析了三峡水库区滑坡发育与斜坡相对高差之间的关系。所得研究结果与实际情况吻合较好,为库区以后的规划建设提供了有力的依据。
英文摘要Landslides occurrence in the Three Gorges Reservoir are influenced by many factors that may be subgrouped into
external factors and internal factors, and relat ive elevations of slope is one of the internal conditions. In this paper the
authors used the method of contributing rate with Geographical Information Technology( GIS) to study how relative elevation
contribute to landslide occurrence. The authors found that the slope contributes most whose relative elevation is 500m to
1000m, and this zone is of dominant importance to develop landslides. As well as, 400m and 1100m to 1300m is the minor
zone which contributes to landslide developing, and 100m to 300m and 1400m to 1700m is the faintish zone in which
landslides develop few. The application of the method of contributing rate may quant ificationally analyze the relation between
landslide and relat ive elevation, and the research result inosculates preferably with reality. The result of this paper can
provide potent gist to the construction of the Three Gorges Reservoir in future.
