中文摘要:
      生物膜群落结构和功能的变化可以反映复合污染胁迫在不同水生态系统中群落水平上的生态响应,对于流域水生态监测具有重要意义和广泛应用前景。选取白洋淀流域典型生态单元水库、府河和白洋淀为研究区,采用活性炭纤维为基质的原位生物膜法,对快速生态监测方法在白洋淀流域不同生态单元的适用性进行了比较研究,并对生物膜与水质指标间的响应关系进行了分析。结果表明:活性炭纤维附着生物膜群落的结构、功能指标与天然基质无显著差异(P>0.05),经过15 d的培养其结构和功能可以很好的表征各个生态单元监测点位的水环境质量,且生物膜群落对于复合污染具有很好的响应。生物膜群落与超标水质参数RDA分析表明,超标指标可以解释生物膜群落变化的63.0%,8个超标水质参数与生物群落相关性大小依次为:DO>TN>CODMn>COD>BOD5>Ecoli>TP>NO3-N。生物膜监测可作为水生态快速监测方法在流域尺度不同生态单元广泛使用。
英文摘要:
      Biofilms respond to different pollutants and could be regarded as a community-level monitoring system for aquatic ecosystems. In this study, we highlighted the potential application of biofilms as a biomonitor in different water bodies in Baiyangdian basin using in situ biofilm formed on carbon-fiber membrane. The correlation between biofilm attributes and water quality was analyzed. The structure and function of biofilms were similar between natural substrates and carbon-fiber membrane in different water bodies in Baiyangdian basin. The biofilms on carbon-fiber membrane after 15 day culture could reflect the situations of different water bodies and be used for ecological monitoring of water quality in Baiyangdian Basin. Biofilms reflected the variation of water quality and main pollutants under complex pollution. Redundancy analysis(RDA) indicated that water quality index explained 63.0% variance of biofilm. The correlation between water quality index and biofilm was in order of DO>TN>CODMn>COD>BOD>Ecoli>TP>NO3-N. The present results suggest that biofilm on carbon-fiber membrane could be recommended as a biomonitor for different water bodies in basin scale.
