摘　　要：在城市景观水体基本完成截污纳管、清淤及生态护岸等工程的同时,运用"以沉水植物主导的水质净化技术",人工构建沉水植物群落、底栖动物群落、鱼类群落、滨水带植物削减缓冲区的全方位一体化水生态体系。利用水生生物食物链的数量金字塔和能量金字塔模型,建立各个营养环节,实现水体营养物质间的有效转移。治理后水体总氮、氨氮、总磷、高锰酸盐指数等主要水质指标均达到国家地表水环境质量标准Ⅳ类水,整个地表水环境质量和生态微环境质量得到明显改善。At the same time of basically completed sewage interception, slitting displacement and ecological embankment, the use of ＂leading the submerged plant water purification technology＂, constructed submerged plant communities, benthic fauna, fish communi- ty, waterfront plant cut buffer of a full range of integrated water ecological system. Based on the quantity of aquatic food chain in Pyramid and Pyramid, the establishment of various nutrition links to achieve the effective transfer of nutrients in water body. After treatment of the main indexes of water quality of the water total nitrogen, ammonia nitrogen, total phosphorus, potassium permanganate index reached the national environmental quality standards for surface water IV water. The land water quality and ecological environ- ment were significantly improved.
