摘　　要：采样的方法决定地质统计学中克立格法的估值精度。以研究区由开采井构成的具有99个地下水位长期观测孔的观测网为例,对地下水大尺度非列线不等距最佳采样网的合理性选择方法进行了研究。以采样点要避免过滤效应、分团效应以及采样数据分布要满足均匀性和随机性的检验准则为原则,选择了具有66个样本点的最佳采样网。The sampling methods decide the Kriging estimation precision in geostatistics. Taking the sampling net which includes 99 long-term water-level observation holes as the example, the proper selection of the methods on the non-alignment and unequidistanee sampling net is studied. The optimum sampling net including 66 observation holes is selected on the basis of the avoidance of filter effects and sub-group effects during the sampling and on the sampling data that meet the testing criterions with uniform and random distributions.
