【摘要】 本文主要综述了土壤空间变异研究的进展,包括土壤水分特征及状态参数、物理性质、化学性质、重金属及其它元素的空间变异研究。讨论了尺度效应及套合结构模型在空间变异研究中的应用和研究进展,指出应根据不同研究目的采用不同的研究方法,并确定恰当的研究尺度,分析统计结果应结合区域生态系统进行分析。更多还原

【Abstract】 This paper reviews advances in the research on soil spatial variability, including soil water characteristics, soil physical properties, chemical properties and heavy metal, etc. It also discusses application of the scale effect and nested structure model and advances in the research. Research scales and methods should depend on the objective of the research and analysis of the statistical results take into account the corresponding regional eco-system.更多还原
