Aiming at the erosion disaster by the"7·27"rainstorm, the rainstorm central area located in Wangjiabian Town, Jiaxian County, Northern Shaanxi Province, was selected as a site to investigate the erosion situations of road, river bank, river channel, housing construction, sloping farmland, afforestation land and natural recovered grassland. Then, several typical slopes with different restoration measures were chosen to measure standing vegetation, topography, soil crust and soil erosion.The effects of different eco-logical restoration measures and recovery levels on soil erosion by the rainstorm were investigated primarily. The reasons for the erosion disaster by the severe rainstorm were analyzed. Results show that vegetation coverage, vegetation species diversity, slope and soil biological crust have the important effects on the rain-storm erosion.
