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最频发的地区之一。要有效防范此类地质灾害必须了解引起滑坡的降雨条件和控制因素。本文依据浙江地区在1990～2007年期间发生的3744处滑坡和同一时期1257个雨量监测站记录的日降雨量数据,总结了滑坡的成因类型,对影响滑坡发生的降雨条件和地质、地形等控制因素进行了分析。Zhejiang Province,located in the southeast costal region of China,is highly prone to rainfall-triggered land-slides due to its geologic,geomorphologic and climatic settings.The effective avoidance and mitigation of the hazard require an understanding of the rainfall conditions and environmental factors that result in landslides.In this article,based on the 3744 landslides occurred from 1990 to 2007 in the region and daily rainfall data from the measurements of precipitation at 1257 rain gauges during the period,we identify the types of the landslides and detailedly analyze the factors resulting in the landslides,including rock types,soil properties,land cover,topography and rainfall.
