摘　　要：通过对三峡库区6个县市近60年降雨数据的逐年分旬统计分析,得出三峡库区每年因降雨产生滑坡灾害的风险时间段主要集中在2月中旬—11月下旬,其中4月上旬至10月中旬出现降水导致滑坡灾害的概率相对较大,这为三峡库区因降雨导致的山地滑坡灾害的预防提供了参考。The statistical analysis of 6 county cities＇ annual rainfall data for nearly 60 years were analyzed. Though that we concluded the general high risk time segment of landside hazards caused by rainfall mainly concentrated in late mid-February to late November, in which early April to mid-October was especially at higher risk. This study provided a reference to mountain landslide disaster prevention due to rains for the Three Gorges reservoir area.
