【摘要】 在对小窑湾海水交换、海域环境现状、底质环境、养殖区生物代谢产生的IN、IP以及浮游植物消长的研究中 ,首次发现了在没有陆域污染源入海的海湾型双壳贝类筏式养殖区养殖生物产生的IN、IP与浮游植物消长有其独特的平衡关系和制约机制 :一方面养殖贝类排泄的IN、IP被浮游植物利用 ,另一方面贝类摄食又控制了浮游植物的爆发性增殖 .同时解释了养殖区水质质量相对较好的原因 .图 3表 4参 15更多还原

【Abstract】 The seawater exchanges, environment characteristics, sediment, IN and IP,phytoplanktons and their growth in the Xiaoyao Bay were studied. The results for the first time clarified that: in intensive raft cultured area without runoff and other pollution, the IN and IP cycling and the growth of phytoplanktons have their special pattern. On one hand, the IN and IP can be used sufficiently by phytoplanktons. On the other hand, raft culture organisms consume phytoplanktons and make phytoplanktons less. At the same time, the main reasons for improveing seawater quality were given. Fig 3, Tab 4, Ref 15更多还原
