The black soil region in northeast China is an important grain base. Water erosion is the main type of soil erosion in the area and increasingly severe which has become one of the most significant factors threatening the food security. To more effectively prevent water erosion, better protect the local ecological security and further promote the construction of ecological civilization, a series of studies were conducted in black soil region of northeast China, including the mechanism, forces, prediction techniques and prevention measures of water erosion in black soil area, have achieved fruitful results. On the purpose of clarifying the existing research results and contributing to the future research on water erosion in black soil region, this review summarized the progress on the water erosion in black soil region of northeast during recent years and found although the current water erosion researches in black soil region were profound and comprehensive, in-depth researches should be further explored in some areas such as quantitative expression on the process of water erosion, systematic assessment of the effect of water erosion, the establishment of prediction model related to water erosion and the integrated management system for water erosion in black soil region of northeast China.
