Preventing water erosion,improving land productivity and minimizing deposition in the Three Gorges reservoir area are the main targets that the constructors are working for in environment resource economy constructions and in slopping land utilization.The application of plant hedge rows is an effective way to realize these targets.It was shown in the experiments in Zigui County,by the Institute of Geographical Sciences and Natural Resources Research of the Chinese Academy of Sciences,that such technique has the ability to effectively control erosion and to improve soil fertility and crop yields.The 7 years old plants in the hedge row are above 90 cm high.At this time,the slope gradient can be reduced from 30°～34° to 15°～18°.The contents of organic matters can be increased to 1.61% from 0.9%.The yields of orange on the terraced farmlands between hedge rows are higher by 20% than those on the terraced land without hedge rows.The yields are 25% higher than those on the rainfed slopping lands.The technique can by widely extended in the area.
