| 长江每年有上千万吨有机物质注入河口邻近海域，影响着这一海域独特的生态环境。
本文根据1985年8月至1986年5月专业调查资料,论述了长江口邻近海域溶解有机碳(DOC)和颗粒有机碳(POC)的分布及变化，并从有机物质的变化推测三峡工程对河口海生态系的影响。 |

| Abstract: |
| The distribution and variation of particu late organic carbon(POC) and dissolved organic carbon (DOC) in and around the Changjiang River Estuary are studied from summer in 1985 to spring in 1986, for the first time. The concentrations of POC and DOC were affected by the freshwater of the Changjiang River, so POC and DOC are directly proportional to salinty. The determined concentrations of POC and DOC are in the range of 0.5-1.4mgC/L and 2.1-5.6 mgC/L repectively. The average concentrations of POC and DOC are 3-4 times and 30-40 times higher than that in deep waters. There is a correlation between DOC or POC and temperature to some extent, higher in summer and lower in winter. |
