摘要: 根据2011年4月、2014年5月在南日岛人工鱼礁区及邻近海域进行的2次生态环境调查资料,研究投礁前后南日岛海域浮游植物的群落特征。结果表明:两次调查共鉴定浮游植物3门40属82种。2011年共鉴定3门32属52种,拟建礁区中心及四周和对照区种类组成相似,平均种类数分别为26种/站和27种/站,细胞数量分别为3.34×104个/dm3和5.68×104个/dm3。投礁前浮游植物丰富度平均值为1.750,物种多样性指数平均值为2.206,均匀度平均值为0.464,优势度平均值为0.753。2014年共鉴定3门34属60种,礁区中心及四周和对照区种类组成相似,平均种类数分别为35种/站和32种/站,细胞数量分别为1.07×104个/dm3和1.05×104个/dm3。投礁后浮游植物丰富度平均值为2.504,物种多样性指数平均值为3.424,均匀度平均值为0.672,优势度平均值为0.551。

Abstract: Based on the investigation on phytoplankton between before-casting reef (April, 2011) and after-casting reef (May, 2014) in artificial reef area around Nanri Islands, the community characteristics of phytoplankton were studied. The results showed that, a total of 82 species which belong to 40 genera of 3 phyla were identified in survey area. Before casting reef, there were 52 species belonging to 32 genera (3 phyla) of phytoplankton. The reef area including around area (with 26 species per station) and control area (with 27 species per station) had similar community structure, and the average cell abundance was 3.34×104 cell/dm3 and 5.68×104 cell/dm3, respectively. In survey area, Margalef richness index was 1.750, Shannon-weaner diversity index was 2.206, Pielou evenness index was 0.464, and dominance index was 0.753. After casting reef, there were 60 species belonging to 34 genera (3 phyla) of phytoplankton. The reef area including around area (with 35 species per station) and control area (with 32 species per station) still had similar community structure, and the average cell abundance was 1.07×104 cell/dm3 and 1.05×104 cell/dm3, respectively. In survey area, Margalef richness index was 2.504, Shannon-weaner diversity index was 3.424, Pielou evenness index was 0.672, and dominance index was 0.551.
