- Abstract:
- By choosing soil of 3.5-year-old Eucalyptus grandis plantations such as pure Eucalyptus grandis, Eucalyptus grandis+grain crops, Eucalyptus grandis+fruits as researching sites, and abandoned farmlands as control, soil anti-erodibility including the mechanical composition, the drying sieve aggregate, disintegration rate, water stable index in hilly area of central Sichuan basin were inverstigated. The results showed that there was significant difference among the soil mechanical composition of different land model. The physical clay content was in the sequence of pure Eucalyptus grandis > abandoned farmlands > Eucalyptus grandis+fruits > Eucalyptus grandis+grain crops.The sand grain content was in the order of pure Eucalyptus grandis < abandoned farmlands < Eucalyptus grandis+fruits < Eucalyptus grandis+grain crops. There was significant difference among the drying sieve aggregate composition of different land models. The order of soil collapse rate follow the sequence of pure Eucalyptus grandis < abandoned farmlands < Eucalyptus grandis+fruits < Eucalyptus grandis+grain crops. Fouthermore, the soil collapse rate of pure Eucalyptus grandis increased in vertical direction insteadly, but decreased in the other 3 models. The order of water stable index was pure Eucalyptus grandis > abandoned farmlands > Eucalyptus grandis+fruits > Eucalyptus grandis+grain crops. On the other hand, the water stable index of pure Eucalyptus grandis reduced in vertical direction, insteadly, but increased in the other 3 models. According to the above analysis, the conclusion was that the order of soil anti-erodibility of different land types was in the sequence of pure Eucalyptus grandis < abandoned farmlands < Eucalyptus grandis+fruits < Eucalyptus grandis+grain crops.
