• 摘要：海河流域是我国人为干扰最为强烈的流域之一,流域内许多湿地的结构功能受损严重,鱼类、底栖生物、大型水生植物缺失,因此鱼类、底栖生物完整性指数(F-IBI,B-IBI)不适用于严重受损的湿地健康评价,在流域尺度上应用具有局限性,而生物膜广泛存在于任何水体中,可以用于流域尺度的湿地健康评价.本文根据生物完整性指数理论,在生物膜基本特征和人为干扰对生物膜的效应机制分析基础上,分析了生物膜评价湿地健康研究进展,探讨了生物膜方法应用于强人为干扰下海河流域湿地生态系统健康评价的可行性和应用前景.并从生物膜整合、尺度转换、健康标准制定、主要影响因子和装置与方法改进5个方面对生物膜法应用于海河流域湿地健康评价进行了展望,以期为海河流域的生态修复和环境管理提供新的思路和方法.

• Abstract：The Haihe River Basin is one of the most intensively human-disturbed basins in China.The structures and functions of many wetlands in the Haihe River Basin have been badly damaged.Alarge number of fishes,benthic organisms and aquatic macrophytes have disappeared,so the index of biological integrity based on fishes or benthos (F-IBI,B-IBI) cannot be used to assess the health of the seriously damaged wetlands.Therefore,these methods have limitations and disadvantages for wetland health assessment at the basin-scale.As biofilms can exist at any water interface,they might be used for basin-scale wetland health assessment.On the basis of the index of biological integrity theory and the mechanisms of the effects of human disturbance on biofilms,current studies on wetland health assessment using biofilms are summarized.In addition,the feasibility and prospects of wetland health assessment in the Haihe River Basin using biofilms are analyzed.Finally,the future directions for study are proposed,including the components of biofilms integration,scale conversion,health standard construction,main health impact factor analysis and device and method improvement,in order to provide new ideas for ecological restoration and environmental management in the Haihe River Basin.
