土壤水分渗透及其管理

INFILTRATION OF WATER INTO SOIL AND MANAGEMENT CONSIDERATION

作为重要的水文学过程，对渗透从理论模型、影响因素及减少机理角度进行了回顾。两个管理因子——耕作与放牧—同减少渗透有关的一些重要方面亦进行了分析。结果表明，就提高渗透而言，以残茬保留及植被覆盖形式的表面覆盖比任何其他管理措施更重要。

Infiltration as a important hydraulic process was reviewed in terms of the oretical models, influential factors and reduction mechanisms. Some important points of two management aspects, tillage and grazing, with relation to infiltration reduction. It was concluded that surface mulching in the form of stubble retention and vegetative coverage is more important than any other management option in improving infiltration.
