- Abstract:
- The research on the forest anti-erosion and anti-scour characteristics of 4 typical forests(mixed wood,broadleaf forest,bamboo forest and shrub forest) in Jinyun mountain in Chongqing City in Three Gorges Reservoir areas shows that,the forest soil anti-erosion indexes is 1.3～1.9 times arable farmland,and the maximal is shrub forest(78.4) ,the minimal is broadleaf forest(53.3) .The anti-erosion index is lessening with the soil layer deepening.The anti-erosion indexes have close relations with soil capillary porosity,non-solid permeability,capillary porosity,length of 1 mm root.Except bamboo forest soil,other forest soil anti-scour coefficients are more than one of arable land(be 1.2～1.9 times) ,the anti-scour capacity is the result of mutual function of related factors.
