摘　　要：简要分析了温州城市河道堤岸的现状结构及其对环境生态造成的影响,提出了温州城市河道绿化植物的选择及河道生态修复技术。以温州市区河道横河为例,采用耐污性强的活性微生物制剂,结合各种功能性水生植物的生物性能,及采用陆生植物的水培技术和生物浮岛技术、生物膜技术、曝气复氧技术等综合技术来分解、吸收水体的污染物质,再利用滤食性水生动物的介入来转移水体的污染物质,达到人工重建河道水生态系统的目的。研究表明,城市河道水体的富营养化和环境生态等问题可以采用生态修复技术进行治理。该工程的成功实践与应用推广为城市景观河道生态修复提供了一种新的参考方案。Embankment structure of Wenzhou urban rivers and its influence on ecological environment were analyzed.As the results,plant greening and arrangement and ecological restoration technique were proposed.Based on Wenzhou urban river ＂Heng River＂ in this paper,multiple technology and filter-feeding aquatic animals were applied to decompose,absorb and then transfer the pollutant in the water to restore ecosystem of river banks.The multiple technologies was combined with activated microbial agents with high antipollution characteristic,functional aquatic plants with biological properties and land plants with hydroponic technique,biology-floatingisland technique,biofilm process and re-aeration technique.Research showed that ecological restoration technique could be used to treat eutrophication water and environmental ecological problems.The practice and spread of this project provides new reference scheme for ecological restoring of city landscape river.
