【摘要】 通过二维水动力弥散实验,模拟地下水污染物的运移过程,并选取反距离平方加权法、趋势面法、普通克立格法和方位-分维法对实验数据进行估值效果的比较。在实验尺度下的比较结果表明,普通克立格法是研究地下水污染物浓度空间分布的最优估值方法。更多还原

【Abstract】 The transport process of groundwater contamination was simulated by 2dimensional hydrodynamic dispersion experiment.Four kinds of spatial estimation methods,including inverse distance square weight,trend surface,ordinary Kriging,and direction-dimension method,were chosen to compare the estimation veracity of the experimental data.The results in the scale of experiments show that ordinary Kriging method is the optimum method for estimating the spatial distribution of the contamination concentration in groundwater.更多还原
