| 摘 要： | 根据2008年1—12月的调查数据，对闽江口海域海水中的COD和DO分布状况与特征进行周年的研究表明，闽江口海域全年的COD含量为0．63～1．70mg／L，符合第一类海水水质标准，季节性变化的规律不明显，受闽江冲淡水的影响，海水中的COD平面分布呈现近岸高，向外逐渐降低的趋势。海水中的DO含量为5．46—8．03mg／L，海水中DO较充沛。尽管受闽江每年向闽江口海域输送大量COD的影响，但是海水中的COD含量仍然较低，该海域具有较大的COD环境容量。

| Abstract: | According to the survey data in the Minjiang River Estuary during January to December, 2008, the content of COD ranges in 0. 63 to 1.70 mg/L without obviously seasonal change, which reaches the first class of seawater quality standard. By the impact of the diluted water of Minjiang River, seawater in the COD plane appears the distribution trend of high concentration near the shore and decreasing outward. DO content in the seawater ranges in 5.46 to 8.03 mg/L, which means abundant content in seawater. In spite of a lot of COD carried by Minjiang River into the sea, COD content is still low, indicating a large environmental capacity of COD in this sea area. |
