利用2002年5～7月对杭州湾淡化对虾养殖虾池水环境中氮磷营养盐的调查资料,分析了该养殖水环境中氮磷营养盐的存在形态与行为,结果表明:(1)在该养殖水环境中,IP含量随时间变化不大,相对较稳定;(2)IN含量的变化主要受生物活动控制,在养殖过程中变化较大,NO3-N为IN的主要存在形态,但在养殖后期,NO2-N含量有所增加;(3)该养殖水环境中氮磷营养盐含量均超过富营养化阈值,因而已无法判断浮游植物生长的限制因子;(4)叶绿素a与IN含量成显著负相关,而与IP含量的相关性不显著。
Based on the survey data of nitrogen and phosphorus nutrients in shrimp ponds shrimp ponds in Hangzhou Bay from May to July in 2002, the existing forms and behaviors of nitrogen and phosphorus nutrients in the aquaculture water environment were analyzed. The results showed that: (1) In the aquaculture water environment, the content of IP changed little with the time, and was relatively stable. (2) The change of IN content was mainly controlled by biological activities and changed greatly during the culture. NO3-N was the main form of IN, (3) The content of nitrogen and phosphorus nutrients in the aquaculture water environment exceeded the threshold of eutrophication, so the limit of phytoplankton growth could not be judged. (4) The content of chlorophyll a and IN A significant negative correlation, while the correlation with the IP content is not significant.
