| 摘 要： | 根据1997年4－12月间对大窑湾牡蛎湾牡蛎养殖区的生态环境调查结果，讨论了该养殖水域叶绿素a含量分布特征和季节变化，对初级生产力进行估算。结果表明，大窑湾浮筏养殖区叶绿素a含量上于较低水平，平均为1．02mg/m^3。叶绿素a含量分布呈现出明显的季节差异，秋季较高。初级生产力的分布与叶绿素a含量分布存在差异，丰季最高，海水透明度可能是造成这种差异的重要影响因子。 |

| Abstract: | On the basis of the data of ecological and environmental surveys about the oyster cultural waters of Dayao Bay between April to December in 1997,the distributing characteristics,seasonal changes of chlorophyll a and the primary productivity of seawaters are discussed and estimated respectively.The results are as fellows:The contents of chlorophyll a in investigating waters are in low level ,with average 1.02 mg.m -3 .The distribution of chlorophyll a appears a obvious seasonal difference,the highest values of chlorophyll a in autumn.While the distributions of primary productivity are different from the chlorophyll a ,the highest figures in summer.The transparencies of sea water seems to be the main reason for that difference. |
| Keywords: | Dayao Bay chlorophyll a primary productivity distributing characteristics |
