  • 摘要: 运用一个耦合的生物物理模型模拟了渤海初级生产力,浮游植物生物量和氮磷含量的季节变化特征,模拟结果与实测值吻合较好。在模型验证的基础上,进一步考察了两种营养盐负荷——河流和沉积物对渤海生态系统动力过程的影响,发现河载营养盐对渤海生态体系的影响主要集中在河口水域,而限制沉积物中的营养盐进入水体则能显著抑制渤海范围内藻类水华的爆发。
    Abstract: A coupled bio-physical model is used to simulate the seasonal variation of primary production,chlorophyll a,nitrogen and phosphorus in the Bohai sea,and the modeled results agree with the observations reasonably. Based on the validated simulations,the impact of two external nutrient sources on the Bohai ecosystem is further examined. It is found that the influence of river-borne nutrients mainly concentrate on estuaries,whereas the reduction of sediment-borne nutrients may seriously inhibit the onset of algaelbloom in the whole Bohai sea.
