摘　　要：为准确分析地下水的空间流场分布,以粤港澳大湾区某典型化工企业地块为研究对象,获取地块内48个监测井的地下水埋深数据并进行正态性分析,分别采用不同的变异函数模型(球面函数、指数函数、高斯函数)对地下水埋深数据进行普通克里金插值对比研究,经过交叉验证方法进行最优理论模型的选择。结果表明:球面函数的插值精度最高,能准确反映地下水埋深空间分布规律;运用实测的地下水流向、地形判定的地下水流向验证了普通克里金球面变异函数模型拟合的地下水流场的准确性。该研究为地下水流场空间插值提供了一种新思路和方法借鉴。In order to accurately analyze the spatial flow field distribution of the groundwater,a typical chemical enterprise plot in the Guangdong-Hong Kong-Macao Greater Bay Area was taken as the research object. The groundwater depth data of 48 monitoring wells in the block were obtained and analyzed by normality. Different variogram models(spherical function,exponential function and Gaussian function)were used to compare with ordinary Kriging interpolation,and the optimal theoretical model was selected by cross validation method. The results showed that the spherical function had the highest interpolation accuracy and can accurately reflect the spatial distribution of the groundwater depth. The accuracy of the groundwater flow field fitted by the ordinary Kriging(spherical function)was verified by using the measured groundwater flow direction and the groundwater flow direction determined by the terrain. This study provided a new idea and methods which can be a reference for the spatial interpolation of the groundwater flow field.
