耕作和压实过程影响土壤水力特性和土壤水流。土壤的保水性和输水性随孔隙几何形状的变化而改变。土壤-水流动不仅受土壤水力特性的影响,还受土壤系统中水源和汇的分布的影响。耕作和压实可以改变土壤孔隙的几何形状,它们还可以通过改变表面形态、表面残留物覆盖和作物根系分布来影响水源和汇。本文回顾了文献,并提供了显示耕作和压实对土壤水力特性和水流影响的数据和关系,提出了一些耕作管理系统的数值模拟水流,并确定了耕作相关水文学研究的未来方向。
Tillage and compactive processes affect soil-hydraulic properties and soil-water flow. Soil-water retention and transport properties are altered in response to changes in pore geometry. Soil-water flow is affected not only by soil-hydraulic properties but additionally by the distribution of sources and sinks of water in the soil system. Tillage and compaction can alter soil-pore geometry, and they can also affect sources and sinks of water by changing surface configuration, surface residue cover, and crop rooting distribution. This paper reviews literature and presents data and relationships showing the effects of tillage and compaction on soil-hydraulic properties and water-flow, presents numerically modeled water-flow for some tillage management systems, and identifies future directions for tillage-related hydrologie research.
