摘　　要：以宜昌两个时段的降雨为研究对象,基于五种传统降雨模式,结合湖北滑坡预警资料,根据择近原则判断各站点降雨过程与五种模式的贴近度,得到三种危险组合雨型,即中间大+中间大组合雨型(Ⅰ型)、减弱+中间大组合雨型(Ⅱ型)、均匀+中间大(Ⅲ型)。通过分析资料和统计结果,为滑坡的预测和防治提供参考资料。Easy to cause landslide in Yichang two times when a rain as the research object,based on five traditional rainfall patterns,combined with Hubei landslide warning data,according to the principle of choose the close to determine the site and degree of five models of rainfall process,get three dangerous combination type,the rain is big and middle combination between rain type（ Ⅰtype）,weakening and combination of middle big rain（ Ⅱtype）,even with large（ Ⅲtype） in the middle. Through the analysis of data and statistical results,it provides reference for landslide prediction and prevention.
