Red soil erosive area is the key region of soil and water conservation in Guangxi Province.Based on research and investigation,the approach of ecological reconstruction is studied by selecting fine soil and water conservative plants disposing method in the erosive region.After 5 years experiment,the results show that the complex model of agriculture and forest which combines arbor with shrub,grass and vine can not only control soil erosion,but also restore eco-environment.The vegetative coverage increases from 10%-30% to 60%,runoff amount and sediment yield decrease more than 70% and 90% respectively.The soilfertility significantly increases,and the content of N,P,K increase by 2.72%-900%.The eco-economic benefits is significant.
