| 摘 要： | 土壤水力特性的空间变异是影响土壤中水分及溶质运移动态的主要因素.70年代以来国内外有关学者就土壤水力特性空间变异进行了大量的试验研究,通过对试验结果分析,得出了许多可供参考的结论,如水力特性空间变异尺度随研究区域尺度的增大而增大,且两者呈一定的比例关系,大多数水力特性遵从对数正态和正态分布,这些结论对于研究区域溶质(污染物)的迁移动态以及区域水盐动态预报十分重要的参考价值.

| Abstract: | The spatial variability of soil hydraulic properties is one of the most important factors which have great effects on soil water and solute movement.The experimental study on spatial variability of soil hydraulic properties since 1970s have been rev ie wed in this paper,and the experimental results have also been analyzed.It can be seen that there is a good relation between the correlation scale of the soil hydraulic properties and the field scale of interesting,the probability density function for parameters of soil hydraulic properties are normal distribution and lognormal distribution,etc..All the results are valued for analyzing the behavior of solute or contaminant transport in aquifers as well as the risk monitoring of field soil regime. |
