摘要

摘要: 本文建立了一个气候态驱动的台湾海峡物理-生态耦合模型（ROMS-NPZD）。与遥感观测数据的比较表明，模型能够较好地模拟出冬、夏季台湾海峡主要的温度和叶绿素分布特征。模型揭示了夏季台湾海峡营养盐输运的东、西通道，与南海次表层水的入侵通道一致；冬季，海峡中的营养盐来源于闽浙沿岸水和通过澎湖水道入侵的南海次表层水。模拟结果表明：夏季，通过海峡流入东海的氮主要为有机氮；冬季，闽浙沿岸流为海峡和南海北部陆架提供了丰富的营养盐，不仅如此，南海次表层水进入海峡的营养盐通量与夏季相当。

Abstract: A physical-biological coupled model (ROMS-NPZD) was built with climatological forcing conditions in the Taiwan Strait (TWS). Comparison between the model and remote sensing data shown the model could capture the climatological characteristics of temperature and chlorophyll in the strait. The model result identified that, the east and west routes of the nutrient transportation that were coincident with the intrusive routes of South China Sea (SCS) subsurface water in the TWS in summer; by contrast the nutrients were source from the Min-Zhe coastal water and the intrusive SCS subsurface water via the Penghu Channel in winter. The model result illustrated the nitrogenous contribution from the strait to the East China Sea (ECS) was mainly composed by PON in summer; in winter the Min-Zhe coastal water supplied abundant nutrient from the ECS to the strait and northern SCS. In addition to that, the nutrients fluxes from the SCS subsurface water into the TWS were comparative between in summer and winter.
