哑铃湾网箱养殖水环境中的营养盐含量及特征

Content and character of nutrient in water environment of cage culture, Yaling Bay

根据2002年4月和7月对哑铃湾网箱养殖海区水化学的现场调查,分析了N、P的存在特征、含量及其它们之间的原子比,结果说明:春、夏季哑铃湾水体中溶解态无机氮主要以氨氮为主;活性磷酸盐为无机磷的主要存在形式。从两季3个调查区域N/P可以看出春、夏季N是哑铃湾海区浮游生物生长的限制因子,而水产养殖可能增加水体P的含量,并且降低水体中的氮磷比。

Based on the field investigation in April and July 2002 in the cage cultural water area, Yaling Bay, the existent character, content and N/P ratio are discussed. At last the article concluded that the main form of the dissolved inorganic is ammonia and the main form of the inorganic phosphorus was the dissolved phosphorus, and that nitrogen is the limited factor the growth of the plankton in sea area , Yaling Bay, and that the aquiculture can be able to decrease the ratio of the nitrogen and phosphorus.
