Abstract:

The erosion gully has caused a large amount of soil loss on the sloping farmland in the black soil area of northeast China. Research on the erosion gullies on the sloping farmland in the black soil area is of great significance for soil erosion control, farmland protection and ecological restoration. At present, relevant researches had been carried out on the influencing factors, prediction and prevention measures of the occurrence and development of erosion gullies on slope farmland in black soil area. This article conducted an in-depth discussion on the current research, and pointed out that the current classification of erosion gullies in black soil areas lacked detailed standard classification basis, and the research on the influence factors was not comprehensive enough, and there was a lack of effective quantitative evaluation on the economic and ecological benefits of erosion ditch management and the effect differences of various treatment measures. In view of the existing research deficiencies, the study proposed that future research should be focused on standardizing the classification and grading system of erosion gullies in the black soil area, the influence of factors such as soil, plants, engineering measures and farming measures on the erosion gullies, and the quantitative evaluation of the effects of erosion gully control measures.

Key words: erosion gully in black soil area, soil erosion, growth, engineering measures, vegetation measure, farming measures
