切沟侵蚀研究现状与存在问题分析

Current Situation and Existing Problems of Gully Erosion Research

切沟侵蚀在现代土壤侵蚀过程中中占据重要地位,其对流域侵蚀产沙有重要贡献。从切沟发展阶段划分、切沟发展过程的主要方式、切沟侵蚀影响因素、切沟侵蚀预报模型和切沟侵蚀测量技术等方面较全面叙述了切沟侵蚀研究现状,提出了切沟侵蚀研究亟待加强的研究领域有：切沟侵蚀发生演变过程、切沟侵蚀影响机理,切沟侵蚀预报模型,切沟侵蚀研究法与技术。

Gully erosion plays the important role in current soil erosion process and it has a great contribution to sediment yield at watershed scale. This paper overviewed classification of gully developement stage, gully development process, the factors affecting gully erosion, gully erosion prediction models, and measurement technology. It also proposed strengthening research fields, including gully erosion occurrence and development process, affecting mechanisms of gully erosion, gully erosion prediction model as well as research method and technology aror gully erosion.
