中文摘要: |
农田生态系统中的物质迁移涉及了系统中各部分水分、溶质、养分及侵蚀过程中泥沙的运动,在农业、水资源、环境等领域都起着重要的作用,一直是人们关注的焦点。对近年来国内外农田生态系统中的水分、溶质和养分迁移的研究工作进行了评述,并指出了需进一步研究的问题。 |
英文摘要: |
The matter transfer in ecosystem of farmland involves the movement and transport of the water, solute, nutrient and bed-load with the system and among the subsystems. It has been paid more and more attentions all over the world in the fields of agriculture, water resources, environmental sciences and so on. In this paper, the recent researches on the movement and transport of the water, solute, nutrient and bed-load in farmland ecosystem are reviewed and the research prospects in future are pointed out. |
