摘要

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材料进行配置，研究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，他表径流量和土壤侵蚀量分别削减70%和90%以上，上壤肥力显著增加，N、P、K等养分含量分别提高2．72%～900%，生态经济效益显著。

Abstract

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

K increase by 2.72%-900%.The eco-economic benefits is significant.
