【摘要】 建立了一个包括浮游植物、浮游动物、无机氮和磷、溶解态与悬浮有机物及溶解氧七状态变量的浅海水体生态动力学箱式模型，并且考虑了海面太阳辐照度变化、海水与底泥温度变化以及营养盐海底溶出和陆源流入的影响。初步分析了在胶州湾北部浮游生态系统演变的几个特征时期动力学方程中的物流动态特征。结果是比较合理的。更多还原

【Abstract】 A pelagic ecosystem model for shallow sea is built, in which a total of seven state variables are included. They are phytoplankton, zooplankton, DIN,DIP,DOC,POC and dissolved oxygen (DO). The effects of solar radiation, water temperature and bottom temperature, nutrient exudation from sea bottom and inflow from land are considered. In the paper, analyzed primarily are the dynamic features of mass fluxes of pelagic ecosystem of the northern part of Jiaozhou Bay, based on the model results corresponding to the different physiological stages. The results are reasonable.更多还原
