中文摘要	本文给出了复合型泥沙灾害的定义，从时间序列角度出发，表述了复合型泥沙灾害过程的复杂性、周期性、耦合性及层次性等特征，并对泥沙灾害的区域关联性而区域差异，区域划分与分区特征作了研究，根据复合泥沙灾害过程发育的大环境及基本复合过程进行划分，分为东部平原一沿海地带复合泥沙灾害过程地区、中部高原低山复合泥沙灾害过程地区、西北干旱高中山盆地复合泥沙灾害过程地区、青藏高寒山复合泥沙灾害过程地区4个一级区；依据泥沙灾害复合过程的相似性及差异性，划分11个复合泥沙灾害过程二级亚区
英文摘要	In this paper the composite sediment disaster process is defined as a compound of sediment disasters, which are formed under a given natural condition and by human activities in a certain space and time span and are with inherently interrelated. Generally speaking, it can be divided into two main types based on its forming dynamics. One is naturally carried out and the other is human induced. From time series viewpoint, it is explained that the composite sediment disaster has complexity, periodicity, anatomists and administrative levels.The regional characteristics of composite sediment disaster process have also been studied. They are relatives, differences and dividing characters. Based on principle environmental features and basic composite processes the whole country can be divided into 4 main regions of composite sediment disasters. They are ( I ) the eastern China plain and coast zone, (II ) the middle China plateau and lower mountainous area, ( III ) the north~ western China arid high and middle mountainous and huge basin area, and ( IV) the Qing-hai-Xizang Plateau and highest mountainous area. According to composite sediment similarities and differences the 11 sub regions has been divided as follows, I_1Sub-region of flood type of composite sediment disasters in the north-eastern China, I_2 Sub-region of flood type of composite sediment disasters in the northern China and lower and middle Yangtze River plain, I_3 Sub-region of flood-storm tide type of composite sediment disasters along coast in the south-eastern China; II_1Sub-region of arid water-soil lose type of composite sediment disasters on Loess Plateau,II_2 Sub-region of flood-slide-debris flow type of composite sediment disasters of Sichuan, Guizhou, west Hunan and Hubei, H 3 Sub-region of slide-debris flow type of composite sediment disasters of west Sichuan and Yunnan;III_1 Sub-region of composite sediment disasters in Inner Mongolia,III_2Sub-region of windy-sand type of composite sediment disasters in Xinjiang and Gansu, III_3Sub-region of slide-debris flow type of composite sediment disasters in Tianshan mountain ; IV_1 Sub-region of slide-debris flow type of composite sediment disasters of the highest mountain in the south-eastern Xizang, and IV_2Sub-region of slide-debris flow type of composite sediment disasters of high Plateau in the north-western Xizang.
