To establish a spatial semivariogram model of human population genetic structure.
目的建立人类群体遗传空间结构异质性变异函数模型。
Results the spatial semivariogram model revealed the spatial genetic structures of a human population.
结果实例表明，模型客观地反映了人类群体遗传空间结构异质性和空间自相关性。
The results indicated that the semivariogram of total C , available N and available K were best described by the Gaussian model, while available P was best fitted by the Spherical model.
结果表明，海伦黑土全碳、碱解氮和速效钾半变量函数曲线的理论模型符合高斯模型，速效磷的理论最佳模型为球状模型。
