摘　　要：本文针对常规目标函数聚类法在聚类过程中不能确定最佳分类数的缺陷 ,应用Fuzzy伪F统计来确定最佳分类数 ,并应用该方法对某河流附近的 15个观测孔的水位动态进行分类 。Fuzzy pseudo F\|statistic is used to determine the best cluster number during the clustering procedure to remedy the shortcoming in conventional objective function cluster method. The said technique is used to classify the water level regime of 15 observation holes nearby certain river and satisfactory results are obtained.
