大亚湾大鹏澳养殖海区水化学指标的变化及营养状况分析

Analysis of nutritive status and variation of hydrochemical indexes in seawater of aquaculture area at Dapeng' ao Bight in Daya Bay

根据 １９９４年 ７月和 １０月、１９９５年 １月和 ４月对大亚湾大鹏澳养殖海区的现场调查，统计了各水化学指标的变化范围和平均值；讨论了Ｎ／Ｐ值的季节变化；以ＣＯＤ、ＴＩＮ、ＰＯ~３－_４－Ｐ和Ｃｈｌ－ａ为分析指标，用营养状态质量指数（ＮＱＩ）分析了该海区的营养状态；并用叶绿素法估算了养殖海区的初级生产力。

Based on the field investigation in July and October 1994, January and April 1995, the variation range and mean of the hydrochemical indexes in the seawater at Dapeng' ac Bight in Daya Bay were obtained. The seasonal variation of N/P value was discussed, the nutritive status (showed by nutritive quality index-NQI) in the studied seawater aquaculture area was analysed based on the indexes of COD,TIN,PO^3_4-P and Chl-a. The primary production was priliminary estimated from Chl-a.
