| 摘 要： | 长阳县位于鄂西南山区，地质灾害发育严重，全县各类地质灾害点459处，其中滑坡287处、崩塌139处，不稳定斜坡13处、地面塌陷12处、泥石流8处，发育特征呈集中分布，北边集中分布在沪蓉西高速公路等交通要道沿线，南边主要分布隔河岩库区两岸。区内地质灾害发育影响因素为地质环境条件和气象、水文条件、人类工程活动。其地质环境条件对地质灾害的发育类型、规模分布起控制作用，即内动力因素；气象、水文及人类工程活动是地质灾害发育的诱因，即外动力因素。

| Abstract: | Changyang county which is located in southwest Hubei province is greatly suffered from geological disasters. The total number of various geological disasters is 459 in statistics, which is including landslide of 287, collapse of 139, unstable slopes of 13, ground subsidence of 12 and mud -rock flows of 8. Those geological disasters are distributing along the Shanghai -Chengdu Expressway in the north and the two banks of Geheyan reservoir in the south. The happen of geological disasters are determined by factors such as geological environment, hydrological condition, meteorological condition and human activity etc. The internal factors, especially geological environment condition, control the type, location and size of geological disasters; whether the external factors, such as meteorological, hydrological and human activities, are the inducement of geological disasters. |
