摘要
本文将模糊综合评判应用于滑坡堵江区域危险度评判。选取了对滑坡堵江事件影响较大的地质地貌、地震烈度、河床水动力条件等方面的１０个参评因素，先在同类因素间进行初级评判，利用初级评判的结果进行类之间的二级评判，以此研究了岷江上游的典型河段和支流的堵江危险度，介绍了滑坡堵江危险度评判的方法与步骤。
he fuzzy compresive evaluation is applied to estimate landslide damming risk degree of damming a river in this paper. 10 factors which attibute to the landslide damming greatly are chosen, including geology and geomorphology, intensity of earthquake and hydrodynamics in river. First of all, preliminary evaluations are proceeded in the same type. Then the senior evaluations is proceeded with the results of preliminary evaluations between the all types. As an example, the typical river segment and tributaries of the upper reach of Minjiang River, at the same time, the method and steps of evaluation on landslide damming risk degree are introduced.
