【摘要】 根据2001-2003年广西沿海渔业生态环境调查监测数据,对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、有机污染情况进行了全面分析与评价;对营养水平指数E值、有机污染指数A值取值及评价标准进行了探讨;通过对水体叶绿素a含量的测定,评价、分析了该增养殖区水域初级生产力水平;监测结果表明该增养殖区水质总体上处于贫营养状态,初级生产力水平很低;应进一步研究该水域养殖容纳量,进行科学、合理的规划,调整养殖布局,以取得更好的经济效益和生态效益。更多还原

【Abstract】 Based on investigation date about Guangxi coastal fishery ecological environment from 2001 to 2003, this paper analyses and evaluates the temporal-spatial distribution characteristic of nutritional level and organic pollution in seawater quality at different periods in Lianzhou Bay, Hepu county, Guangxi. To set the values about E-value (nutritional level index) and A-value (organic pollution index) and their evaluation criteria were also discussed. By measuring chlorophyll-a concentration in the waters, primary productivity was estimated. According to the results, in general, the nutritional level of the waters is poor and the primary productivity is very low. Therefore, aquaculture capacity should be further studied to plan the waters scientifically and reasonably, adjust fishery placement and achieve better economic and social benefits.更多还原
