摘要
通过文献研读,本文评述了国内外有关浮游藻类与河流生境关系的相关研究进展,归纳总结了相关研究数据,在此基础上提出了对有关研究未来发展趋势的一些展望。研究结果表明:①浮游藻类特征与河流生境关系密切,现有的相关研究显示,中国河流中硅藻门、绿藻门和蓝藻门种属所占的百分比,浮游藻类的平均细胞密度等特征,在一定程度上可反映河流的生境特征;②国内外迄今的理论研究和应用案例表明,在流速较缓的大河中下游河段,浮游藻类的特征可作为评估和指示水生态系统健康状况的有效指标;③中国浮游藻类与河流生境关系问题的基础研究仍较薄弱、系统性不强,需要加强调查与分析,建立不同类型河流中浮游藻类的本底特征数据库,构建适合我国河流水生态系统健康评估和监测的浮游藻类指标;④以各类地表水体中的浮游藻类与其生境关系为基础,开展浮游藻类功能群分类研究,探讨其在水生态系统健康评估中的应用等,是国际浮游藻类生态学研究中的新趋势。我国相关研究刚刚起步,建议今后应重视整合湖泊与河流生态系统中的研究结果,加强浮游藻类与生境关系的系统研究,创建我国浮游藻类功能群分类系统,尽快实现我国浮游藻类研究与国际接轨。
Based on a meta-analysis of international and Chinese studies, we reviewed developments into the relationship between phytoplankton and river habitats. The analysis showed a close relationship between the features of phytoplankton and river habitats among various types of rivers. It has been universally proved from both theoretic research and applied case studies that features of phytoplankton can be used as effective indicators to show the health of mid-to downstream river water ecosystems with slower flow velocity and wider riverbeds. Basic and systematic research into phytoplankton and river habitats is still limited in China, and lacks integration. More field investigations are needed, as is support from laboratories and a database of phytoplankton. Future research trend will likely focus on the classification of phytoplankton with emphasis on functional types, and applications of this classification to the assessment of water ecosystem health. In order for Chinese research to reach an international level we recommend integrating all research results related to phytoplankton already conducted in various lakes and river ecosystems in China,reinforcing systematic research into the relationship between phytoplankton and habitat, and developing China＇ s own classification system based on functional types.
