摘　　要：对可变模糊聚类迭代模型进行了深入分析,通过与指标等权重的著名的ISODATA模糊聚类迭代模型比较,论证了可变模糊聚类迭代模型的合理性与收敛性;同时指出ISODATA模糊聚类迭代模型是可变模糊聚类迭代模型一个特例.列举了水资源系统中的一个应用实例——年径流中长期预报,检验了可变模糊聚类迭代模型的实用性.The variable fuzzy clustering iterative model （VFCIM） was analyzed deeply. By comparing VFCIM and well-known ISODATA clustering iterative model with equal index weights, the rationality and convergence of VFCIM were demonstrated. At the same time, it is pointed out that the ISODATA clustering iterative model is a special case of VFCIM. An example is enumerated in the field of water resources, that is mid-long term runoff forecasting, which verifies the practicality of variable fuzzy clustering iterative model.
