| 摘 要： | 滑坡时间分布是滑坡预测和预警报研究的关键内容,对一定区域滑坡分布时间规律的研究可为区域滑坡预测和预警报提供参考和指导。本文以长江三峡库区滑坡为研究对象,对滑坡的年际分布和月份分布的相似性分别进行了研究。结果表明,两种时间的分布规律具有较好的相似性,且滑坡规模越接近,相似性程度越高。对滑坡时间分布的相似性研究,为应用分形理论研究该区域滑坡时间分布规律提供了理论基础。

| Abstract: | The time distribution of landslides is a key subject for research of their prediction and forewarning.The study of regularity of time distribution of landslides in a particular area can provide a guide for the prediction and forewarning of landslides in that area.In this paper,landslides in the Three Gorge Reservoir have been considered to study the similarities of their yearly and monthly distributions.The study has shown that the time distribution of landslides in different time scales are well similar,an... |
