摘要

基于一个三维、高分辨率、水动力泥沙生态数值模式,综合考虑多种物理及生态因子,模拟研究了长江口及闽浙海域甲藻和硅藻两种浮游植物生物量的时空分布规律.数值实验的结果表明,该海域藻类生长主要集中在春末、夏季及秋初,硅藻有春季和夏季两次水华,而甲藻仅在春季发生一次水华.该海域浮游植物的高值区主要集中在30-50 m等深线附近.该处是外海高温、低浊度水体与近岸低温、高浊度、高营养盐长江冲淡水的交汇区域,满足浮游植物生长所需要的外部物理环境和内部营养盐需求.本文进一步探讨了径流、陆架环流等关键物理过程对浮游植物生长的影响.

Abstract

This study was based on a highresolution, threedimensional, physicsbiogeochemistry coupling numerical model that considered multiple dynamics and biochemical factors to simulate the spatial and temporal distribution of the dinoflagellata and diatoms. The results showed that the algae bloomed in late spring, summer and early autumn in this area. The diatoms bloomed twice in spring and summer and dinflagellata bloomed only once in spring. The high phytoplankton mass concentrated around the area of 30 to 50 isobath, which was an frontal area between the high temperature and low turbidity shelf waters and the low temperature and rich nutrient Changjiang diluted water. This area satisfied the physical and biogeochemical requirements for the growth of the phytoplankton. Furthermore, we also analyzed the influences of the physical dynamics such as runoff and shelf circulation on the phytoplankton growth.
