结合最新的研究结果, 本文对中国大型海藻区系划分、区系的种类组成、分布特征、研究成果、现状和存在的问题等进行了介绍、总结和分析。目前, 中国海藻区系可划分为4个小区, 即黄海西区、东海西区、南海北区和南海南区。大型海藻物种数达到1,277种, 其中蓝藻门6目21科57属161种(及变种)、红藻门15目40科169属607种(及变种)、褐藻门11目24科62属298种(及变种), 绿藻门11目21科48属211种(及变种)。简要地介绍了它们的区系分布、垂直分布、时空变化等方面的分布特征。文中还对我国大型海藻的研究现状及存在的问题进行了简短分析, 以期有益于我国大型海藻多样性研究的发展。

Herein, we introduce, summarize, and analyze the taxonomy, species composition, distributional characteristics, major research results, and current status of Chinese marine macroalgae with updated references. The China sea flora can be divided into four sub-floras, viz. the western region of the Yellow Sea, the western region of the East China Sea, and the northern and southern regions of the South China Sea. More than 1,277 species of marine macroalgae were recorded along the China seas coast, including 161 in Cyanophyta, 607 in Rhodophyta, 298 in Phaeophyta and 211 in Chlorophyta, respectively. We briefly introduce the overall distribution, vertical distribution and spatial-temporal changes of marine algae located within the littoral area. We analyze some problems which limit the study of Chinese marine macroalgae, including difficulties in sampling and habitat deterioration. Moreover, classic taxonomy has not been attached enough importance and has not been updated with molecular techniques, and lack of talents.
