摘　　要：1988年5月、8月、11月和1989年2月东山湾海水的盐度范围分别为20.81～33.89、30.43～34.24、26.76～30.59和30.27～31.57;水温范围分别为23.4～25.0、22.5～30.8、18.1～20.7和14.5～17.3℃;溶解氧体积分数分别为(4.12～4.91)×10^(-3)、(3.50～5.10)×10^(-3)、(5.21～6.68)×10^(-3)和(5.64～6.00)×10^(-3);氧饱和度分别为85.1%～104%、73.3%～116%、99.6%～124%和102%～104%。春、夏季东山湾受高盐外海水的影响明显,其中夏季可能还受到上升流的影响.秋季浮游植物大量生长和繁殖,成为溶解氧含量和氧饱和度的主要影响因素。The distribution of salinity,temperature and dissolved oxygen in the surface and bottom water of Dongshan Bay,Fujian was investigated on four seasonal cruises between 1988 and 1989. Salinity was 20.81～33.89,30.43～34.24,26.76～30.59 and 30.27～31.57; temperature was 23.4～25.0, 22.5～30.8,18.1～20.7 and 14.5～17. 3℃;the volume fraction of dissolved oxygen was(4.12～4.91)×10^(-3), (3. 50～5.10)×10^(-3),(5.21～6.68)×10^(-3) and (5. 64～6.00)×10^(-3);the saturation degree of oxygen was 85.l%～104%,73.3%～116%,99.6%～124% and 102%～104% in May,August,November of 1988 and February of 1989 respectively. The distribution of these components and the results of linear regression analysis indicated that temperature was negatively correlated with salinity in both summer and winter, that the distribution of dissolved oxygen and the saturation degree were mainly affected by the upwelling over the Minnan-Taiwan Shoal Fishing Ground and the photosynthesis of phytoplankton in the Bay in August,that the distribution of dissolved oxygen and the saturation degree were niainly affected by the photosynthesis of phytoplankton because of the phytoplankton bloom in November and, that the content of dissolved oxygen was negatively correlated with temperature in February.
