摘　　要：1988年5月、8月、11月和1989年2月东山湾海水中活性磷酸盐的浓度分别为0.10～0.55、0.02(未检出)～1.63、0.04～0.73和0.19～0.71μmol/L,平均值分别为0.23、0.34、0.38和0.50μmol/L。活性磷酸盐的分布特征和多无线性逐步回归的结果表明,活性磷酸盐浓度的主要影响因素随季节的不同而变化,其中1988年8月湾口和湾东侧区域明显受到上升流的影响。The concentration and distribution of soluble phosphate in the surface and bottom water of Dongshan Bay, Fujian Provine were investigated through four seasonal cruises between 1988 and 1989. The concentration range of phosphate was 0.10～0.55, 0.02(N. D.)～1.63, 0.04～0.73 and 0.19～0.71(μmol/L in May, August,November of 1988 and February of 1989 respectively, and the mean concentration was 0.23, 0.34, 0.38 and 0.50μmol/L respectively. The step by step multiple linear regression revealed that the growth of marine phytoplankton in the Bay may be limited by phosphate in the spring, that the distribution of phosphate in the summer was affected by the upwelling over the Minnan-Taiwan Shoal Fishing Ground and the utilization of phytoplankton in the Bay,that the distribution of phosphate in the fall was mainly affected by the utilization of phytoplankton because of the bloom of phytoplankton.
