| 摘 要： | 本文根据１９９１年１２月至１９９２年１月在普里兹湾及其邻近海域所作的现场观测，采用红外分析法测定了表层水和大气ＣＯ２分压，结果表明，表层水ＰＣＯ２的分布大致呈近岸低、远岸高的特征，其分布变化主要受生物活动控制。利用通量计算模式，估算出ＣＯ２在调查海域的平均海－气通量为－７１．９ｇ／（ｍ２ａ），通量的可能误差主要来自与风速有关的交换系数。

| Abstract: | The partial pressure of carbon dioxide in surface water and atmosphere in the Prydz Bay and its adjacent waters was determined by using infrared analysis from December 1991 to January 1992. The results showed that the distribution of P CO 2 in surface water appeared to be lower in the coastal sea than the open sea,and its distribution was principally controlled by biological activity. The CO 2 flux was estimated by using the flux model, the mean CO 2 air-sea flux in the research area was about -71.9 g/(m 2·a),its potential flux uncertainties might result from the wind dependent exchange coefficient. |
