| 摘 要： | 以各生长期有效降水和敏感性系数为依据选取聚类指标，利用模糊迭代聚类方法对多年降水资料进行聚类分析；在此基础上建立了GM（1，1）模型，检验其精度；并对未来农业水分盈亏变化趋势进行预测。实例计算结果表明：该方法简便、精度较高，具有一定的实用价值。

| Abstract: | Firstly,this paper chooses the cluster's index based on the valid precipitation in each growth period and the sensitiveness coefficient,and then utilizes fuzzy clustering iteration model to cluster the data of many years precipitation of irrigation section;then forms the GM(1,1) model and inspects its accuracy;finally,forecasts the change tendency of the profit and loss of agricultural moisture in the future.The effect of application show that this method is convenient,current and the precision is preferably,which has some feasible value. |
