| 根据“三峡工程对长江河口区生态与环境的影响和对策”的研究要求,为掌握工程兴建前长江口环境状况,我们于1985年8月一1986年5月,对122°-124°E,30°45′-32°00′N海域及受潮汐影响的江段进行了调查。本文根据5个航次的调查资料阐述了长江口海域化学耗氧量(COD)的分布特征。 |

| Abstract: |
| The construct of the Three Gorges Project will have a great effect on ecology and environment of the Changjiang River. Estuary. In order to understand the present environmental state of the Estuary before the construct of the Project, five cruises in different seasons were carried out in 122°-124°E, 30°45′-32°00'N sea areas and the river sections affected by tides The surveys indicate that COD average concentration reachs a maximum of 2.73m /L in May, nd a minimum of 1.18mg/L in October. By the results of the surveys the paper discusses the characterestics of COD distribution in the Changjiang River Estuary. |
