| 摘 要： | 从2007年3月至2008年2月,对厦门海域的同安湾和九龙江河口的溶解氧进行每30 min的连续监测。结果表明,厦门海域的溶解氧含量随潮汐的运动表现出很强的规律性。其表现形式有双峰双谷、单峰单谷和双齿状特征,特别是溶解氧随潮汐下降的过程中回带现象明显。从湾内和河口的统计比较看,湾内的溶解氧日平均含量高于河口3.2%,而日差平均值低河口26.4%。

| Abstract: | Every 30 minutes,there have been continuously monitored the dissolved oxygen(DO) of the Xiamen sea areas along Tongan Bay and Jiulong River Estuary during the period from March,2007 to Febuary,2008.Results indicated that the DO level in the areas mentioned above regularly varied with the tidal flow and there were three diagrammatic forms featured as dual peaks and valleys,single peak and valley as well dual dentation.It could be obviously observed that the DO level of seawater dropped significantly with the ebb tide.By compared with the results from two surveying sites,it could be found that the average level of Tongan Bay was higher 3.2% than that of the Jiulong River Estuary,but the daily variation of DO average level was lower 2.64% in the bay than that of outlet. |
