摘　　要：针对新乡原阳县黄河滩区堤南干渠周边面临的主要农业污染类型,利用干渠生态治理工程中的展示节点,进行了边坡植物带防治农业污染的冲刷模拟试验。在试验过程中遵循植物多样性和季节性的原则,混合建植了7种边坡植物。试验结果表明,边坡植物能够显著地降低农业生产导致的地表径流污染,其作用效果表现为植物覆盖土地>裸露土地,且对氮元素的移除效果大于对磷元素的移除效果,并进一步讨论了边坡植物防护带对农业污染物的净化机理。According to the main types of agricultural pollution around the main canal of Dinan in Yellow River beach area of Yuanyang County, Xinxiang City, the experiment of slope vegetation prevention and control of agricultural pollution was carried out by the display nodes in the ecological management project of the main canal. According to the principle of plant diversity and seasonality, 7 kinds of slope vegetation were mixed and planted during the experiment. The experimental results showed that slope vegetation could significantly reduce the surface runoff pollution caused by agricultural production, and the order was covered land > bare land. The removal effect of nitrogen element was greater than that of phosphorus element. The purification mechanism of slope vegetation on prevention of agricultural pollution was also discussed.
