摘要
土壤孔隙结构是土壤结构的重要方面,土壤大孔隙引起的优先流和溶质优先迁移与地下水污染、养分流失和灌溉水浪费都有着密切的关系;对土壤孔隙结构的研究具有重要的实践意义和指导作用。本文在综合国内外研究文献的基础上,对前人研究进行系统总结,介绍土壤孔隙结构的获取手段、孔隙结构的表征和模拟方法,并且对今后土壤孔隙结构研究的热点进行了展望,以期为今后进行土壤孔隙结构建模的深入研究提供帮助。
Soil pore structure is an important part of soil structure. Preferential migration of flow and solute that caused by soil macropores is closely related to groundwater pollution, nutrient runoff and waste of irrigation water. Therefore, the study of soil pore has important practical significance and guidance. This paper describes the means of getting soil pore structure, pore structure characterization and simulation methods. Besides, outlook of the hot research of soil pore structure is presented, with a view to offering help for intensive study of modeling the pore structure.
