| 摘 要： | 以浮游植物量、浮游动物量、营养盐浓度 (包括无机氮和无机磷 )以及碎屑量为生态变量 ,在HAMSOM水动力学模式的基础上构建了 1个三维浮游生态动力学NPZD模型。采用此模型研究了渤海 1999年浮游植物量和初级生产力的变化情况 ,模拟结果与实测基本相符。模拟结果表明 :1999年渤海浮游植物量的变化大致呈双峰分布 ,春季水华出现在4,5月份 ,秋季水华出现在 9,10月份 ;受透明度和局地水深的影响 ,渤海湾和辽东湾北部浮游植物量的年变化呈夏季大、冬季小的单峰分布。 1999年渤海不同海区初级生产力的变化特征是 :除莱州湾一年中有春、夏 2个峰值外 ,其它 3个海区都是夏季高、冬季低的单峰分布 ;1999年整个渤海年平均的初级生产力为 2 5 7mgC/m2 /d。

| Abstract: | On the basis of HAMSOM, a three-dimensional dynamical NPZD model for the Bohai Sea plankton ecosystem is constructed with phytoplankton biomass(P), zooplankton biomass(Z), nitrite, phosphate(N) and detritus(D) as the state variables. By using the relatively new data sets for the topography, wind and river runoff as forcing, and the data from two joint Sino-Germany cruises in 1998 and 1999 for the initial inputs and validations, the annual cycles of phytoplankton biomass and primary production of the Bohai Sea in 1999 are simulated, and they are overall in good agreement with the observations. The results indicate that the annual variation of phytoplankton biomass in most areas of the Bohai Sea is double-peaked and algae break out in spring and autumn, while in Bohai Bay and the north of Liaodong Bay the variation is one-peaked, probably owing to transparency and local depths in the three other regions. The annual variation of primary production is double-peaked in Laizhou Bay and one-peaked in the other three regions. The mean value of primary production in the Bohai Sea is 257 mgC/m2/d in 1999. |
