soil hydraulic conductivity

基本解释

A model for the unsaturated soil hydraulic conductivity is established based on an assumption that the soil can be represented as a continuum fractal porous medium.
土壤的孔隙是具有连续分形性质的物理结构，根据土壤孔隙分形结构建立了非饱和水力传导度模型。
Soil hydraulic conductivity is closely related to the movement of water and salts in soil profiles and is highly affected by solution salt concentration and its composition.
水力传导度的变化直接影响土壤剖面的水盐运动，并和土壤溶液的盐分浓度及其组成有很大关系。
The theories and application about methods of parameter determination on soil hydraulic conductivity in fields are reviewed, and the advantages and disadvantages of those methods are analyzed.
