| 摘 要： | 由于独特的地理位置,复杂的地质、地形和气候背景,浙江成为中国降雨型滑坡（土体和岩体滑动,也包括泥石流和崩塌等）最频发的地区之一。为评价浙江地区的滑坡灾害,本文对该地区1990年至2003年雨量站记录的降雨数据进行了详细分析,确定了引发土体滑坡-泥石流的降雨强度―历时下限。 |

| Abstract: | Zhejiang Province, located in the southeast costal region of China, is highly prone to rainfall-triggered shallow landslides （soil slides and debris flows） due to its geologic, geomorphologic and climatic settings. With the aim of contributing to the landslide hazard evaluation of the region, a detailed analysis of the rainfall events that have resulted in landslides is carried out. Rainfall data recorded at the main raingauge of the region from 1990 to 2003 are analysed and compared with the occurrence of the landslides. Regional and some local rainfall intensity-duration thresholds for the initiation of landslides are defined for Zhejiang Province. |
