摘要
随着城镇污水收集处理能力的不断提高,农业面源污染逐渐成为黄河流域尤其是引黄灌区天然河流的主要污染来源,其治理成为流域水污染防治面临的重点和难点。当前,农村水系综合整治和水美乡村建设为引黄灌区退水的生态净化提供了条件。对黄河流域3种优势沉水植物的生境特征、氮磷去除能力和环境适应能力进行了分析比较,为基于引黄灌区农业面源污染输移过程拦截和原位治理的分布式沉水植物湿地系统的构建提供了科学依据。
With the continuous improvement of urban sewage collection and treatment capacity,agricultural non-point pollution has gradually become the main pollution source of natural rivers in the Yellow River Basin,especially in the Yellow River Irrigation Area,whose treatment has become the key point and difficult point of water pollution control.At present,the projects of“rural water system improvement”and“villages with enchanting water”provide conditions for the ecological purification of the returned water in the Yellow River Irrigation Area.In this paper,the habitat characteristics,nitrogen and phosphorus removal capacity and environmental adaptability of three dominant submerged macrophytes in the Yellow River Basin are analyzed and compared,which provideds a scientific basis for the construction of distributed submerged macrophyte wetland system based on the interception during transportation and in-situ treatment of agricultural non-point pollution in the Yellow River Irrigation Area.
