通过对北京市市区浅层地下水多年最高地下水位在不同方向分布的实验结构函数的计算 ,套合出了二维结构函数模型 ,并综合运用“交叉验证法”与“离散方差检验法”对该模型进行了检验 Through the calculation of the experimental structural functions of multi-year maximum groundwater table in Beijing urban area, the two-dimensional structural function model is set up and the cross-validation method and the discrete variance test method are used synthetically The model was tested
