摘要： 本文基于非结构网格有限体积法海洋模型FVCOM(Finite Volume Community Ocean Model)耦合NPZD（Nutrient-Phytoplankton-Zooplankton-Detritus)，构建东海生态模型对2021年氮磷营养盐和浮游植物进行了模拟，并对营养盐增加、透明度降低、海温上升组合极端情况进行了评估。结果表明，FVCOM-NPZD能够较好模拟东海营养盐的全年季节变化，并能体现东海浮游植物的空间分布特征。透明度降低有助于长江口下游营养盐降低，可能加剧下游磷限制；海温升高会改变浮游植物藻华暴发时间和空间分布季节特征，但是整个生态系统对缓解营养盐负荷加剧的能力极为有限。本研究有助于理解综合极端条件下生态系统的响应特征，并为构建更复杂的东海生态系统模型提供了基础。

Abstract: Based on the unstructured-grid finite-volume ocean model FVCOM (Finite Volume Community Ocean Model) coupled with the NPZD(Nutrient-Phytoplankton-Zooplankton-Detritus) model, this study develops an ecological model for the East China Sea to simulate nitrogen and phosphorus nutrients as well as phytoplankton dynamics in 2021. Combined extreme scenarios, including increased nutrient loads, decreased water transparency, and elevated sea surface temperature, are evaluated. Results indicate that the FVCOM-NPZD model can reproduce the annual seasonal variations of nutrients in the East China Sea and effectively capture the spatial distribution characteristics of phytoplankton in the region. Increased water transparency contributes to the reduction of nutrient concentrations downstream of the Changjiang Estuary and may enhance phosphorus limitation in the downstream area; elevated sea surface temperature alters the timing of phytoplankton bloom outbreaks and the seasonal characteristics of their spatial distribution. However, the capacity of the entire ecosystem to mitigate the intensification of nutrient loads is extremely limited. This study facilitates the understanding of ecosystem response characteristics under combined extreme conditions and provides a foundation for developing more complex ecological models for the East China Sea.
