从沟灌侵蚀机理的角度出发,分析了沟灌水性质、灌溉水作用方式对沟灌侵蚀影响的主要研究成果,及其与一般降雨径流侵蚀的区别;分析了国内外主要沟灌侵蚀预报模型发展的研究成果及存在的主要问题;分析了实践中沟灌侵蚀防治方法的主要研究成果。结合中国沟灌侵蚀研究的实际情况,提出了今后一定时期内在沟灌侵蚀研究方面的发展设想与研究思路。
First, from the view of the erosion mechanism, the main achievements in the furrow irrigation erosion (FIE) affected by the characteristics of irrigation water and the mode of irrigation action are analyzed. The primary differences between the furrow erosion from irrigation and the erosion from rainfall in the farmland are explained. Next, the prediction model for the furrow irrigation erosion is introduced, and the primal problems of the prediction model is brief described. Then, the prevention and the cure technique for the FIE are presented. Finally, the tentative plan on the research of FIE in China is proposed.
