| 摘 要： | 1990年5月和11月对大管岛礁区潮下带大型底栖海藻进行了两次定量调查。共采到23种大型海藻，其群落构成以红藻类占优。海藻种类的区系温度性质属明显的温水性区系。5月份平均生物量为240．939／m2，11月份平均生物量为164．399／m2。两季度月都以岛西侧的D7断面平均生物量最高，分别为820．159／m2和472．509／m2。就垂直分布而言，1—2米水层内海藻分布密度最高，达527．549／m2。优势种为海蒿子和石花菜。

| Abstract: | The benthic algae were quantitatively investigated in the reef area of sublittoral in the Daguan Island in two seasonal months, May and November of 1990,A total of 23 species were collected. There were more species of Rhodophyta than those of other algae. The marine algal flora of the reef area in the Daguan Island was obyiously temperate in nature. The average biomass was 240.939/m2 in May.and 164.399/m2 in Noyember. The average biomass on the west side of the Island was the highest in the two seasonal months, 820. 159/m2 and 472.59/m2 respectively.Regarding to the vertical distribution, the algal density reached its maximum value (527.549/m2) in the 1--2m water layer. The dominant species were Sargassum pallidum and Gelidium amansii. |
