本文取自福建省海岸带及台湾海峡西部海域调查资料,通过温度与盐度之间、硅酸盐与盐度之间、硅酸盐偏差与浮游植物个数之间的相关分析,来研究不同水系消长及浮游植物的摄取对硅酸盐含量变化的影响,结果表明硅酸盐含量变化主要受三种水系交错混合的影响,春季浮游植物的摄取也是显著的影响因素. Based on the survey data of the coastal zone of Fujian Province and the western part of Taiwan Strait, this paper studies the correlation between temperature and salinity, the correlation between silicate and salinity, the deviation of silicate and the number of phytoplankton Water consumption and phytoplankton uptake on the change of silicate content. The results show that the change of silicate content is mainly affected by interlaced mixing of three kinds of water systems, and the uptake of phytoplankton in spring is also a significant factor.
