秦山核电站邻近水域海水光的穿透性能变化研究

Study on the variation of the optical properties of sea water near the Qinshan Nuclear Power Station

本文运用水体中可见光的传输机理，讨论了光的传输特性与水中悬浮泥沙、色素和黄色物质等的定量关系。同时简述了在秦山核电站邻近海域１９９５年１０月～１９９６年７月间４个航次的有关水光学特征现场测量过程和实验室分析方法。最后，通过水体中太阳光穿透深度和真光层，研究了该邻近海域的光穿透性能的季节性变化。研究表明，核电站运行以来，秦山核电站邻近海域水的光穿透性能变化很小。

The quantitative relationship between the optical properties and the water constituents,such as suspended matter,pigment and the yellow substance,has been first discussed in the paper,using the visible optical energy transmision mechanism in the water.The insitu data measured and the method of used in laboratory analysis were presented for four cruises near the Qinshan Nuclear Power Station.Finally,the solar direct transmitance and optical depth were used to study seasonal variation of the visible optical properties near this marine area.The results show that the solar direct transmitance and optical depth have almost not changed since the nuclear power station run.
