| 摘要: |
| 河口生态环境与渔业资源受多种因素影响，其变化过程与作用机制错综复杂。动态模型的建立可以简单概括其结构，归纳出其基本特征，为定量描述和分析河口生态环境与渔业资源的变化提供有力工具。三峡工程对长江河口区生态环境及渔业资源影响的前期研究工作已初步查清河口及邻近海域的本底情况和一些基本规律(张法高等，1987；刘瑞玉等，1987) ，后期工作又进一步收集整理了大量有关历史资料，这为建立长江口渔业资源模型提供了有利条件。 |

| Abstract: |
| We established the simultaneous equations of state variables by means of stepwise regression and basing on the historical materials of hydrology, meteorology and fishery statistical figures, as a useful tool for calculation of the effects of the Three Gorges Project on Changjiang River Estuarine fishery resources
On the assumption that Three Gorges Project had been built and 180m design conducted the hydrology data can be drawn up according to the design. Using this tool and the simulant data the impacts of the Three Gorge Project on the fishery resources of Changjiang River Estuary are analysed. The results indicate that, upon the whole, the construction of the Three Gorges Project will have no harmful effects on the estuarine fisheris. The draft 180m design can raise CPUE by 0.0171 t/f per year in the Changjiang River Estuary fishery resources. |
