长江口滨海湿地生态修复工程对底栖纤毛虫群落的影响
Effects of the ecological restoration project in the coastal wetlands of the Yangtze River Estuary on benthic ciliate communities
摘要
Abstract
To evaluate the effects of the ecological restoration project involving Bolboschoenus maritimus in the Chongming Dongtan salt marsh wetland of the Yangtze River Estuary on the benthic community,this study employed principal coordinates analysis(PCoA),similarity percentage(SIMPER),and other methods to compare the community structure and diversity of benthic ciliates in the restoration area and the adjacent natural Bolboschoenus maritimus area over four consecutive seasons.The results are as follows:① After restoration,the sediment median grain size,organic matter content,and ammonium levels in the restored area increased significantly;② Significant differences were observed in the species composition of benthic ciliate communities between the restored and natural areas of Bolboschoenus maritimus.Salinity,phosphate,pH,oxidation-reduction potential,and meiofaunal biomass were the primary driving factors;③ The α diversity of the benthic ciliate community in the natural area was significantly higher than that in the restored area.Silicate,salinity,ammonium,organic matter content,and sediment median grain size were the main factors influencing the diversity.In summary,the restored area exhibited a distinct benthic ciliate community composition and lower diversity compared to the natural area,suggesting that a longer recovery period may be needed for the sedimentary environment and benthic ciliate community in the restored area to reach the natural state.关键词
