| 摘 要： | 指出了早期对坡耕地养分流失的研究主要集中于地表径流对其的影响，目前关注于壤中流、地下径流对其的研究。在总结坡耕地养分流失危害、影响因素、过程及特征的基础上，重点综合分析了优先流、壤中流、地下径流3种土壤水分运动对养分流失的影响。

Review of the Impacts on Nutrient Loss of Sloped Farmland due to Soil water movement |
| |
| Abstract: | The sloped farmland is one of the main lands in China. Its nutrient loss not only reduces soil fertility,but also causes the non--point source pollution. Early research on the sloped farmland nutrient loss mainly focused on surface runoff in the process. The present research emphasizes on the effect of subsurface runoff and underground runoff. This paper, based on the summary of the harm of the slope nutrient loss, influence factors,process and characteristics, analyses the preferential flow, subsurface runoff, underground runoff three kinds of soil water movement on the influence of the nutrient loss. |
