Abstract: The relationship between vegetation and soil erosion deserves more attention due to its importance to science and practical applications. While most available information is on the mechanisms and benefits of vegetation for soil erosion control, the interference of soil erosion in plant development and vegetation succession is poorly documented as is the plant’s resistance to soil erosion. Soil fertility and soil water decline during the erosion process reduces seed activity and production and the seeds on the soil surface will be redistributed or lost during soil erosion. While the seeds of some species have special appendages which can help the seeds persist in the soil, seed germination and seedling establishment are the vulnerable stages in plant life. Seed germination and seedling survival are restricted when soil water and fertility are reduced during the erosion process. Simultaneously, the over land flow and sediment redistribution also affect seed germination and seedling survival thus redistribution of seeds, water and sediment will influence the distribution of seedlings and the vegetation. Plants are selected by the environments and develop with the environments, so only some species can grow in habitats stressed with serious soil erosion. Soil erosion works on the environment and different stages of the plant life. Thus the process of vegetation succession is also influenced by soil erosion. In conclusion, plant growth and development are influenced by soil erosion and may express many traits that resist soil erosion. Eroded habitats are colonized by specially adapted plants. We consider that effective soil erosion control strategies in a region can be developed, only if the level of interference of soil erosion in vegetation development and succession and the traits and capacities of different plant’s resistance to erosion are fully considered.
