- Abstract:
- Runoff and sediment data of forest area and non-forest area in the Ziwuling region has been analysed in this paper.The results show that periods of forest being seriously destroyed and reclaimed by human being has showed curves of runoff and sediment change in year.After vegetation being destroyed,correlative relation between runoff and sediment and rainfall is in-creased,but function of forest resisting in rainfall runoff and sediment is weakened.Increaseing value of runoff and sediment in the forest area is bigger than that of non-forest area.Vegetation is a key factor of affecting on soil accelerated erosion.
