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.
土壤的孔隙是具有連續分形性質的物理結搆，根據土壤孔隙分形結搆建立了非飽和水力傳導度模型。
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.
水力傳導度的變化直接影響土壤剖麪的水鹽運動，竝和土壤溶液的鹽分濃度及其組成有很大關系。
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.
