摘要:: 选取厦门集美凤林人造沙滩、人工红树林光滩和龙舟池三个样点，从2009年11月到2010年9月观察研究了浒苔(Enteromorpha)固着和漂浮的野外生长变化规律。结果表明：凤林人造沙滩上的浒苔为固着的缘管浒苔(Enteromorpha linza)，冬季是缘管浒苔的生长繁殖期；春季成熟藻体出现，但生物量减少；夏季，当海水温度超过30℃，肉眼不见缘管浒苔。研究还表明缘管浒苔有多种附着基质，包括砾石、砖石、贝壳、维尼纶网片等，但在砖石上藻体生长最为旺盛。龙舟池发现有石莼科的多种大型藻类，但春夏季暴发的绿潮主要是由石莼（Ulva lactuca）引起的，秋季暴发的绿潮中浒苔(Enteromorpha prolifera)占优势。观察期内未见到成熟期释放孢子的石莼。

Abstract:: The green algae Enteromorpha sp.were sampled at three sites:the artificial beach at Fenglin Site，the artificial mangrove beach and the Longzhou pond，at Jimei District，Xiamen City．From November 2009 to September 2010，the temporal and spatial variation of the attached and planktonic Enteromorpha were investigated,and the attached substrates for Enteromorpha were also recorded.The results showed that all the macro algae found on the artificial beach at Fenglin were E．linza.The E．linza grew fast in Winter,and the mature algae appeared in Spring，but the biomass decreased during this period．In Summer，when the sea water temperature was above 30 ℃,the E．linza were invisible by naked eye．E．linza could grow on a variety of substrates，including gravel，brick，shell and vinylon meshe etc，and the most vigorous growth of algae were observed on the bricks．Six species belonging to the family Ulvaceae were found in Longzhou pond．In Spring and Summer，the green tide was mainly caused by Ulva，whereas in Autumn E．prolifera was dominant．No mature Ulva that could release spores were observed during the investigtion．The results of this study would provide a scientific basis for preventing the outbreak of green tide in Jimei，Xiamen.
