| 摘 要： | 长山列岛自然条件优越，初步调查，底栖海藻共有109种，其中45种属经济海藻。在各大岛屿，潮间带底栖海藻的覆盖度可达4级(50-75％)，许多优势种的生物量较大，如羊栖菜，Sargassum fusiforme(Harv)Setch.海罗Gloiopellis furcala(Postet Rupr)J.Ag、缘管浒苔Enteroniorpha linza(L.)J.Ag.鹿角菜Pelralia siliguosa Tseng et C.F.Chang.肠髓藻M yelephycus caespilosus Kjellm,和海雹菜Brachytichia guoyi(C.Ag)Born et Flah.等。各岛屿藻类的水平分布基本上是由东南向西北递减，即分布在东南端的海洋岛藻类种类最多，獐子岛次之位于西北端的广鹿岛种类较少。调查和分析各岛屿海藻群落的生境，基本属于：岩岸、石砾、泥沙滩和沙滩四种，不过有些生境并不典型常形成混合型。

| Abstract: | We have investigated the five main islands of the Chang-Shan Isles, and collected marine algae amount to seventy-seven genera and one hundred and nine species. Among them,eight species belong to the blue algae, nineteen belong to the green algae, theirty species belong to the brown algae and fifty-two species belong to the red algae. The fourty-five species of these algae belong to the algae with economical value and they make up 45% of the total species of these algae. The resource of these algae is very rich. The coverning rate of these benthic algae in the tide zone reaches Class IV (50-75%). Among them, over twenty species are the predminant ones with high bio-mass, such as Glo-iopcltis farcuta (P. et. R.) J. Ag., Sargassum fusiforuic (Harv) Setch, Pelvetia silliquosa Tseng et C.F. Chang, Gelidium amansii Lamx, Enteromorpha linza(L) J. Ag, Myelophycus caespitosus Kjellm, Sargassum thunbergii (Mert) O'Kuntza, etc. |
