摘　　要：灌区降雨典型水文年的选取直接关系到灌区用水的可持续性和用水安全。文中提出应用模糊相似优先比法选取典型水文年的方法,结合涝河灌区1959-2002年实测降雨资料,首先采用系统聚类法划分出灌区降雨丰水年组、平水年组和枯水年组系列,再利用模糊相似优先比法确定灌区降雨典型年。计算过程中避免了人为的主观性,是一种较为客观的选取典型水文年的方法,为灌区降雨典型年的选取提供了一种新的分析手段。The selection of rainfall typical hydrologic years directly related to water sustainability and water safety in irrigation area. This paper proposed a method to select the typical hydrologic years using fuzzy similarity priority ratio method. The rainfall data from 1959 to 2002 of Lao River irrigation district was clustered by means of hierarchical clustering method, and then the typical hydrologic years were determined by fuzzy similarity priority ratio method. The computation results show that it was an objective method to select the typical hydrologic years. It could avoid human subjectivity in calculation process, and provides a new analytical tool for rainfall typical year selection m irrigation area.
