摘要
文章根据热量平衡和氧量平衡推导出计算公式,求得粤东上升流区海水的垂直涡动系数,垂直混合氧的增加率,生物化学过程氧的净增率,总增加率和消耗率。它们的平均值分别为(3.25±0.59)×10^(-5)m^2/s,(3.96±2.08)×10^(7)L^3/(m^3·s),(3.94±1.86)×10^(-7)L^3/(m^3·s),(26.64±7.30)×10^(-7)L^3/(m^3·s)和(22.7±6.8)×10^(-7)L^3/(m^3·s)。文章还讨论了氧各种过程的分布变化规律,并计算了上升流的上升速度和初级生产力。
Based on heat-oxygen balance, some calculation formulae were derived. Thereby, vertical eddy coefficient, increase rate of vertically mixing oxygen, net increase rate, total increase rate and consumption rate of oxyen in biochemical processes were solved . Mean values for each were (3.25±0.59)×10-5m2/sec, (3.96±2.08)×10-7dm3/(m3 . sec), (3.94±1.86)×10-7dm3/(m3.sec),(26.64±7.30)×10-7dm3/(m3.sec) and (22.71±6.8)×10-7dm3/(rn3.sec), respectively. In the present paper regularities of oxygen distribution in the processes were also discussed and, thereupon, upwelling velocity of the sea water and primary productivity in the upwelling area were calculated.
