【摘要】：以朝营小流域作为研究区,利用标准径流小区法,研究不同植物篱配置模式下的减流减沙效益,径流小区包括:黑麦草、黑麦草+白三叶、白三叶、鸭茅+榛子、鸭茅+金荞麦+木通等5种植物篱模式,并与对照小区玉米地进行对比.结果表明:(1)在喀斯特高原山地各植物篱措施均具有较好的减流减沙效果,相比之下鸭茅+金荞麦+木通三行植物组合模式效果最显著;(2)各小区径流及泥沙流失量由大到小依次为:白三叶、黑麦草、鸭茅+榛子、黑麦草+白三叶、鸭茅+金荞麦+木通三行植物篱;(3)与对照组相比,组合植物篱模式(鸭茅+金荞麦+木通,黑麦草+白三叶,鸭茅+榛子)减流减沙效果优于单一植物篱模式(黑麦草,白三叶).
[Abstract]:Using Chaoying small watershed as the study area, using standard runoff plot method, the benefits of runoff and sediment reduction under different hedgerow allocation models were studied. The runoff plots included ryegrass, white clover, and hazelnut. There were 5 hedgerow patterns in Dactuca arundinacea and buckwheat, and were compared with the corn field in the control plot. The results showed that: (1) all the hedgerow measures in karst plateau had better effect of reducing flow and sediment. In contrast, the effect of the three plant combination models was the most significant. (2) the order of runoff and sediment loss in each plot was: White clover, ryegrass, duck fescue hazelnut, ryegrass white clover, (3) compared with the control group, the combined hedgerow model (Astragalus arundinacea, ryegrass, white clover, hazelnut) was superior to the single hedgerow model (ryegrass, ryegrass). White clove
