| 摘 要： | 土壤侵蚀严重地影响土壤物理和化学性质，限制了作物生产；它对作物生产具有长期和短期效应，短期效应通过施肥和培肥土壤等措施可得到恢复，而长期效应在较短时间内很难得到弥补。土壤氮素随径流流失不仅造成土壤肥力退化，而且对人类生存的自然环境造成危害。

| Abstract: | Soil erosion seriously influences soil physical and chemical properties, and further limits crop production. Its impact on soil properties includes the long-term and the short-term effects. Soil erosion and nutrient loss directly result in soil fertility degeneration, and also seriously threaten the natural environment. |
