摘要
在大比例尺地球化学域内,地球化学变量表现为区域化和协同区域化变量。变量自身及变量之间存在着空间的自相关和互相关,本文提出用二次函数模型拟合变量的自相关和互相关,并以此做为空间因子分析的基础。
Within geochemical field at large scale, geochemical variates are regionalized and coregionalized. Spatial auto-/crosscorrelation occurrences between one variate and itself or and another. In the present paper, a quadric function model is proposed to fit auto-/crosscorrelation of variate. It is the basis of spatial factor analysis.
