For three-dimensional spatial information of deposits in the prediction of buried ore bodies at large-scale, 2d GIS can not represent and analysis very well.

传统的二维gis只能表达面上的信息，对于大比例尺下的隐伏矿体预测中矿床的三维空间信息往往不能很自然地表达与分析。

Spatial scale is forefront in soil-scientific research, so the analysis of macropore reasonable sampling size becomes significant which is in case of taking account of spatial variability.

土壤特性的空间尺度问题是当今土壤科学研究的前沿，在进行土壤空间变异研究中，大孔隙的合理取样尺度分析对大孔隙流研究具有十分重要意义。
