摘  要：
在水源保护区16.5°坡耕地上,种植豆科、禾本科、菊科等多年生牧草,替代传统的种植模式(玉米-小麦)。两年试验结果表明,种植牧草能有效降低水、土及养分流失,径流量、土壤流失分别比习惯种植减小27.6%～35.8%及41.8%～54.6%,氮磷钾养分流失比传统种植减少30.9%～41.3%,其中氮流失减少31.2%～39.4%,磷流失减少29.1%～39.2%。水土保持效果以种植禾本科牧草最好,菊科牧草稍差,豆科牧草及豆科-禾本科牧草混播效果居中。同时种植牧草还能取得较好的经济效益,纯收益比习惯种植增加9.2%～15.0%,是水源保护区种植结构调整及坡耕地综合治理的较好方式。

摘  要：
In the water conservation areas,the study concentrates on planting perennial pastures like bird’s foot,germanous pastures and composite pastures in the 16.5°slope cultivated land instead of the traditional planting mode (corn-wheat).According to the two-year experiments,planting pastures decrease the loss of soil,water and soil nutrition efficiently.Compared to the traditional planting way,the decrease in runoff flow and loss of runoff soil were about 27.6%~35.8% and 41.8%~54.6%.The loss of nitrogen,phosphorus and potassium decreased 30.9%~41.3%,especially the loss of nitrogen cut down 31.2%~39.4% and the loss of phosphorus cut down 29.1%~39.2%.The gramineous pastures have the best impact on water and soil conservation,and the effect of composite pastures is weak.The bird’s foot and the mixture of gramineous pastures and bird’s foot have a batter effect.Plating pastures and other crops at the same time will benefit the economic income.The interests will increase 9.2%~15.0%.It is a better way to adjust the structure of planting in water source reserves and solve the environmental problems in slope cultivated lands.
