| 摘要: |
| 2010年1月、3月、6月及9月,共设14个调查站位对钦州湾茅尾海海域的环境因子及浮游植物的种类组成、优势种类、数量分布和群落多样性进行调查分析。结果茅尾海海区营养盐中PO43-P值为0.01~0.07 mg/dm3,DIN值为0.16~0.78 mg/dm3,PO43-P值和DIN值均有超4类海水水质标准现象。浮游植物共鉴定出82属,262种,优势种类16种,年平均丰度为6.29×104 cells/L,生物多样性指数的年平均值为3.87。2010年茅尾海浮游植物种类和数量都比较丰富,种类的季节变化呈现由冬至秋减少的趋势,数量的季节变化比较明显,春季最低,平均密度仅为3.28×104 cells/L,夏季最高,平均密度为9.25×104 cells/L。 |

| Abstract: |
| Environmental factors, phytoplankton species composition, dominant species, amount of distribution and community structure were investigated in January, March, June and September of 2010 in Maowei Sea of Qinzhou Bay.The results showed that, in the survey area, the concentration of PO43--P was 0.01~0.07 mg/dm3, DIN was 0.16~0.78 mg/dm3, and both values of PO43--P and DIN had scaled over Type Ⅳ water quality standards at some stations.262 species belonged to 82 genera of phytoplankton were identified, and there were 16 kinds of dominant species among them.The phytoplankton abundance average was 6.29×104 cells/L, and the annual average index of biodiversity was 3.87.The species number of phytoplankton had a decreasing trend from winter to autumn.There was an obvious seasonal change in the cell abundance, being the lowest (3.28×104 cells/L) in spring (March) and highest (9.25×104 cells/L) in summer (June). |
