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.
