本文主要讨论了1984年8月至1985年5月东海溶解氧垂直分布和季节变化。结果表明:春、夏季节水体明显分层,密度跃层强度大,春季透光层光合作用强烈,氧的净增量(AO_2)大,在水文条件和生物活动占优势的情况下,春季氧含量形成了垂直分布有一最大值;并且发现跃层上界面以上水体中△O_2和叶绿素a垂直积分值之间存在着相关性,相关系数(r)为0.97(n=9)。△O_2季节变化明显地展示了上层光合作用和底层氧化过程在各个季节的强弱程度,而且间接地反映了春季初级生产力为全年最高.
This paper mainly discusses the vertical distribution of dissolved oxygen and seasonal variations in the East China Sea from August 1984 to May 1985. The results showed that: the water bodies were obviously stratified in spring and summer, the density of the thermocline was high, and the photosynthesis of the translucent layer was strong in spring, and the net oxygen increment (AO_2) was large. Under the condition of hydrological conditions and biological activities, Oxygen content formed a maximum of vertical distribution. Correlation was found between the vertical integrated values of △ O_2 and chlorophyll a above the upper interface of the thermocline, with a correlation coefficient (r) of 0.97 (n = 9). The seasonal change of △ O 2 obviously shows the intensity of the upper photosynthesis and the underlying oxidation process in each season, and indirectly reflects that the spring primary productivity is the highest in the whole year.
