本文分析了1990年厦门岛周围海域浮游植物4个季度月的312份网采样品。结果表明:浮游植物细胞总量年高峰期在河口区出现在夏季,浮游植物种类数与盐度成负相关;在非河口区总量年高峰出现在春季,种类数与盐度成正相关。多元线性逐步回归分析表明,影响浮游植物数量分布的主要环境因子是营养盐、水温、盐度,但因季节而异。骨条藻与硅酸盐呈密切正相关。
In this paper, 312 net samples of phytoplankton in four seasons on the sea around Xiamen Island in 1990 were analyzed. The results showed that the annual peak of total phytoplankton appeared in the summer in the estuary and the number of phytoplankton was negatively correlated with the salinity. In the non-estuary area, the annual peak appeared in spring and the species number was positively correlated with the salinity. Multivariate linear stepwise regression analysis showed that the main environmental factors that affect the distribution of phytoplankton are nutrients, water temperature and salinity, but vary with the seasons. Sarcophyte and silicate are closely related.
