在对小浪底水库下游孟津县扣马河漫滩农业生态调查的基础上,分析了河岸农业性湿地(稻田、鱼塘和荷塘)开发所引起的生态环境影响。通过优化荷塘的耕作制度,有效地协调了滩区水田和旱地之间的需水矛盾,增加了滩区农作物对氮磷的利用效率,减少了肥料流失所引起的水环境污染风险。
The ecological and environmental impacts of riparian agricultural wetlands along the lower Yellow River,including paddy fields,fish pounds and lotus pounds,were studied through a survey on agricultural ecology in the floodplain of Kouma River in Mengjin County in the downstream of Xiaolangdi Reservoir.These agricultural activities in riparian caused serious pollution and significantly lifting the risk of eutrophication.Optimizing farming system of lotus pounds has many advantages.
