壤中流研究进展与展望

Research Progress and Prospects of Subsurface Flow

壤中流是径流的重要组成部分,对流域径流调节、水源涵养、泥沙迁移、养分流失等都具有非常重要的作用,是水文学研究的难点和前沿科学问题。论文介绍了壤中流的概念、研究背景和重要性,对壤中流研究的国内外发展态势和热点研究内容进行了总结,同时分析了壤中流形成的影响因素,总结并讨论了径流小区实验法、地球物理法、模型模拟法、示踪剂方法的研究现状和优缺点,提出了目前壤中流研究中存在的问题,并对未来壤中流研究进行了展望。

Subsurface flow is an important component of runoff, it plays a very important role in drainage basin runoff regulation, water conservation, sediment migration, and the loss of nutrient, it has been the difficulty and frontier issues in the field of hydropedology. This review paper introduced the concept, research background and significance of subsurface flow and summarized the domestic and foreign research development trend and the hot points of the subsurface flow research. What＇ s more, the influence factors of subsurface flow were analyzed. By discussing research statue and summarizing the advantages as well as disadvantages of runoff plot experiment method, geophysics method, model simulation method and the tracer material method, it proposed the problems in the research of sub- surface flow at present, and made a prospect for the future subsurface flow research.
