冲沟侵蚀研究进展

A Review on the Study of Gully Erosion

冲沟侵蚀是一种重要的土壤侵蚀方式,它不但是导致土地退化的一个重要过程,还是江河泥沙的一个主要来源,深入开展冲沟侵蚀研究对于江河生态安全、土地可持续利用意义深远。本文跟踪和报道了国内外冲沟侵蚀的监测方法、控制因素、模型研究等方面的最新进展,在深入分析当前研究不足的基础上,指出了今后我国开展冲沟侵蚀的研究方向和重点领域。

Gully erosion is an important kind of soil erosion, which is not only a key process resulting in soil degradation, but also a major source of sediments in rivers. It is of great importance to carry out research on gully erosion for river＇s ecological security and land＇s sustainable utilization. The present paper gives an introduction to latest proceedings of the monitoring methods, controlling factors and modeling study of gully erosion home and abroad. And then the study orientation for gully erosion in China is pointed out and suggestion on its key study field is proposed as well.
