摘要
论述了灰色ＧＭ（１．１）模型的建立、计算及精确度检验等方法。给出了模型优化的一种途径，即优化参数的方法，并以济南市岩溶泉随时间变化的水位作为实例进行了具体的预报。
GM(1,1)establishing,model calculation,results testing and methods ofprecision analysis have been described in this paper.A method of model optimization isgiven. Regarding to the change of karst spring water level with time in Jinan city,wehave made concrete prediction.
