摘要
指出了养分流失直接导致丰富表土流失、土地退化、生产力水平降低等问题。探讨了坡面产流产沙及坡耕地养分流失特征的研究现状及养分流失的控制技术,为坡地养分流失研究提供理论参考。
Soil erosion and nutrient loss are not only problems of agriculture, but also problems of ecological environment. Nutrient loss directly leads to the rich topsoil erosion, land degradation and declines of productivity levels. Through the research review of runoff, sediment and nutrient loss characteristics in slope farmland and control technology, this paper aims to provide theoretical guidance for research of nutrient loss.
