| 摘 要： | 分析了１９９１年上半年南海大鹏湾盐田水域夜光菏和浮游动、植物之间的种群动态关系，结果表明，在春季高峰期３月至５月初，调查海域共出现１２个夜光藻和浮游动、植物高峰。其中，以发生４次赤潮的夜光藻种群占主导地位，其次是枝角类的鸟啄尖头蚤，其最高数量高达９６２３８ｉｎｄ／ｍ＾３。相比之下，在夜光藻和枝角类岛啄尖头捕食压力的影响下，浮游植物的春季高峰并不显著。调查结果表明夜光藻的过度繁殖，不但对产浮游性卵的

| Abstract: | This paper presents an analysis of the relationship among the N. scintillans population, phytoplankton and zooplankton in Dapeng Bay, the South China Sea, showing that there were 12 peaks of N. scintillans population, phytoplankton and zooplankton in the study area between March - May, 1991. Among these three categories, N. scintillans with four blooms in 1991, was the first dominant, followed by cladocera P. avirostris, with abundance maximizing at 96238 ind./m3. In comparison with them, the spring peak of phytoplankton, especially in diatom, was not so remarkable, the feeding pressure from N. scintillans and P. avirostris being a most probable reason. Another finding in this study was that the N. scintillans population's great feeding pressure on copepoda, crustacean larvae and fish egg & larvae, and remarkably decreased the diversities of zooplankton species diversities.
In the study area, the production peak of N. scintillans phytoplankton or zooplankton shifting in about six-day interval between March and May. This agreed well with the ecological characteristics of coastal eutrophicated waters. For this finding, there are two possible explanations: one is that animals such as N. scintillans and P. avirostris with great variety of foods and strong environmental adaptation can develop earlier than others; another is that the faster material cycle and energy flow due to vertical mixture in the shallow water may be contributive to the increase of productivity. |
