Abstract Based on studying the existing research results and field investigation, the main mode of vegetation succession affected by soil and water conservation, the influence of different soil and water measures (engineering measures, artificial plant rehabilitation, natural eco-restoration) on vegetation succession is analyzed. The results showed that the vegetation succession trend to natural succession under natural eco-restoration. However the influence of artificial plant rehabilitation was restricted completely by choice of species and planting patterns. Normal succession can be accelerated by suitable species and mixed structure; normal succession can be interrupted or conversed by unsuitable species and simple forest planting. The influence of engineering measures on vegetation succession may mainly exhibit on the spatial distribution of vegetation communities. In order to understand and estimate the influence of soil and water conservation measures on regional vegetation succession, the research and investigation should be comprehensive, systemic and scientific.
