摘  要：
以布设的径流小区试验研究结果为依据 ,论述了植物篱防治水土流失、提高土地生产潜力的效益。试验表明 :植物篱地比裸地产流时间延缓 5～ 2 5min ,4年后植物篱最大坎高达到 85cm ,坡度降低 9°～ 11° ,坡长缩短也很明显 ;篱地土壤中有机质提高 15 %～ 68% ,全磷提高 0 3%～ 2 2 % ,全氮提高 5 3%～ 12 0 %。植物篱措施与坡改梯措施相结合将会大大提高生态效益和经济效益。

摘  要：
The paper has discussed the benefits of livin g hedges for controlling soil and water loss and increasing the production poten tiality of land based on the tests and research results of laid out runoff plots . It is shown by tests that the time of yield of the lands with living hedges is postponed 5～25 minutes than that of naked lands.4 years later, the maximum height of the ridge of living hedges has reached 85 cm , the slope reduced by 9°～11° and the length of slopes has been remarkably sh ortened. The organic matter of the land with living hedges has increased 15%～68%, total phosphorus increased 1%～22% and total nitrogen increased 53%～120%. The combination of measures of living hedges with turning sloped land into terraces will greatly increase ecological and economic benefits.
