摘要
东北黑土区水土流失日益严重,沟道侵蚀加剧了珍贵黑土资源的流失,造成耕地面积缩减,严重威胁到东北黑土区粮食生产安全和区域经济稳定发展。本文论述了东北黑土区沟道侵蚀类型、侵蚀现状与发展趋势,分析了侵蚀沟道发育机理,评述了目前主要研究方法及防治技术,提出了东北黑土区沟道侵蚀未来有待加强的研究领域及方向,为继续深入开展东北黑土区沟道侵蚀防治与研究工作提供依据和参考。
Northeast Black Soil erosion is worsening,gully erosion exacerbated by the loss of preciousblack soil resources,resulting in reduction of arable land,a serious threat to the safety of food productionin black soil zone and regional economic stability and development.This article discusses the types ofblack soil erosion gullies,erosion situation and development trend,analyzes the erosion mechanism,review current research methods and prevention techniques,proposed the future research needs to be strengthened and direction of gully erosion control in the northeast black Soil region,and provides the reference for continuing research to carry out the gully erosion control.
