摘　　要：波浪破碎、气泡是中高风速下气体交换速率的关键因子。文章分析计算了气泡和非破碎部分的贡献,并结合热带气旋和近岸海域的特点考虑了悬浮物浓度的影响,进而评估生物在气体交换中的作用。中高风速下气泡对交换速率的贡献为55%~76%。悬浮物浓度整体贡献仅次于气泡对交换速率的贡献,为11%~19%。由悬浮物浓度增大而影响的生物碳循环过程十分重要,研究结果可为量化研究中高风速下CO_(2)气体交换提供思路。Wave breaking and bubble are the key factors of gas exchange rate at medium and high wind speed.In this paper,the contribution of bubbles and non-broken parts is analyzed and calculated,and the influence of suspended matter concentration is considered in combination with the characteristics of tropical cyclones and coastal waters,so as to evaluate the role of organisms in gas exchange.The contribution of bubbles to the exchange rate at medium and high wind speeds is 55%~76%.The overall contribution of the concentration of suspended matter to the exchange rate is second only to that of the bubble,which is 11%~19%.The biological carbon cycle process affected by the increase of suspended matter concentration is very important,and the research results can provide a way to quantify the CO_(2)gas exchange at medium and high wind speed.
