摘要
大孔隙流方面的研究是土壤水运动机理由均质走向非均质领域的标志而成为土壤物理学学目前的研究热点,研究成果对评估土壤污染物风险、确定灌溉、施肥、以及种植作物方案等提供理论依据。围绕大孔隙的分类标准、大孔隙流的影响因素、土壤大孔隙流量化方法3个方面综合介绍了土壤大孔隙流的研究现状,指出目前研究中存在的不足以及今后的发展趋势。旨在为深入研究大孔隙流提供新的思路及参考。;Macropore flow is a natural and ubiquitous phenomenon in soil environment. Research on macropore flow involves studying mechanisms of soil water movement from homogeneous to heterogeneous fields, so it has become research focus in soil physical science. Understanding of mechanisms on macropore flow would provide useful information for irrigation, fertilization, crops planting and pollution tendency simulating. This paper introduces present research situation of macropore flow from classification standards, the influencing factors and quantitative methods, the deficiency of present research and research directions are discussed. The purpose of this paper is to provide some new ideas for deeply studying macropore flow.
