| 摘要: |
| 根据2001~2003年广西沿海渔业生态环境调查监测数据,运用营养指数(E)法、有机污染指数(A)法以及初级生产力情况,分析与评价广西合浦廉州湾增养殖区水质不同时期营养水平时空分布特点、有机污染情况。结果显示该增养殖区水域营养水平指数E值时空变化范围为0.01~1.71;A值为-0.79~0.75;叶绿素a含量为0.31~2.83mg/m3。说明合浦廉州湾增养殖区水域营养水平总体上很低,处于贫营养状态,初级生产力水平低,但水域有机污染程度低,水质较好。 |

| Abstract: |
| Based on investigation data about Guangxi coastal fishery ecological environment from 2001 to 2003,this paper analyses and evaluates the temporal-spatial distribution characteristics of nutritional level and organic pollution in seawater quality at different periods in Lianzhou Bay,Hepu county,Guangxi.The results shows that the temporal spatial distribution of the e-value ranges from 0.01 to 1.71mg/L,the a-value from -0.79 to 0.75mg/L,the chlorophyll-a from 0.31 to 2.83mg/m3.According to the results,in general,the nutritional level of the waters is low and the primary productivity is very low,but the organic pollution is slight and the quality of waters is good. |
