土壤水分入渗影响机制研究综述

Review on Effects Mechanism of Soil Water Infiltration

分析了土壤水分入渗理论及过程模型发展历程,阐明了此领域目前的研究热点。重点对影响土壤水分入渗的结皮、初始含水率、密度、机械组成、结构、有机质含量、温度、钠离子含量及剖面特征等因素逐个做了仔细分析,总结了各因素对土壤水分入渗能力的影响机制。在此基础上,提出土壤水分入渗研究未来研究重点。

The paper analyzed the development history of soil infiltration theory and process models firstly.The main emphasis at present was proposed too.And then,the soil water infiltration influencing factors were analyzed,which contain crust,initial water content,bulk density,mechanical composition,structure,organic content,temperature,Na＋ content and profile characteristic.The mechanism of each factor effects to soil water infiltration capacity was concluded.On that basis,the author proposed the foucs of future research.
