广西水土流失重点区域生态恢复试验研究

红壤侵蚀区是广西水土流失的重点区域。在调查研究的基础上，选择优良水土保持植物料进行配置，进行侵蚀区生态恢复重建的途径。经过５年的试验研究表明，乔灌藤草结合的复合农林模式能有效控制侵蚀，迅速改良生境，侵蚀区植被覆盖率由１０－３０％提高到６０％以上，

Study on Ecological Restoration in the Serious Soil and Water Loss Region of Guangxi Province

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.
