摘　　要：季节性结冰或全年结冰湖泊数量超过全球湖泊的一半,结冰是这些湖泊特有的物理水文过程,影响着湖泊物理和化学环境以及生态系统。气候变暖和水体富营养化引发的冰期缩短、浮游植物物候变化和春季水华提前等生态问题引发了全球关注。本文从三个方面综述了湖泊冰封期浮游植物研究重要进展。首先是湖泊冰封期环境条件及不同阶段理化因子的变化规律;其次是湖泊冰封期变化环境下浮游植物生长、种类组成和群落结构的时空格局及其响应机制;然后介绍了我国目前冰封期浮游植物研究的进展。基于这些研究进展,本文展望了湖泊冰封期浮游植物研究的未来发展趋势,特别是湖泊冰封期生物地球化学过程、湖泊-大气-陆地与气候互馈机制、研究方法与理论模型的构建。More than half of global lakes are seasonally or annually frozen.Freeze is a special physical-hydrological process in frozen lakes,affecting physical and chemical variables of lake ecosystems.Many ecological issues caused by climate warming and lake eutrophication have attracted global attention,including the shortening frozen period,phytoplankton phenological shifts and earlier spring algal blooms.We reviewed the important progress of phytoplankton research during the frozen period in lakes from three aspects.First,we summarized recent progress in various environmental conditions and the variations of physicochemical factors in different stages of frozen period.We then synthesized the temporal and spatial variations of phytoplankton growth,species composition,and community structure under changing environment during the frozen period,as well as their response mechanism.Lastly,we introduced the research progress on phytoplankton during the frozen period in China.Accordingly,the future trends of phytoplankton research during the frozen period are prospected,especially biogeochemical processes,feedback mechanism among lake-atmosphere-land and climate,research methods,and the construction of theoretical models.
