摘要
核电站运行过程中产生的温排水会造成局部海域海水表面温度升高。本文运用MATLAB软件对ETM＋遥感图像进行处理，采用单窗算法对田湾核电站周围海湾的海水温度进行反演，并与海水亮温反演结果进行数据拟合以确定单窗算法的结果精度，探讨核电站对周围海域海水温度的影响。研究结果表明，自田湾核电站运行后，核电站附近海域的海水表面温度呈上升状态，上升幅度在3～7℃。
The generation of nuclear power requires significant discharge of warm water. We used Landsat ETM＋ images collected on May 28, 2006 and May 4, 2009 to examine water temperature around the Tianwan nuclear power plant. Existing algorithms and the MATLAB software were used to edit the remote sensing images to detect variations in seawater temperature before and after operation of Tianwan nuclear power station began. A single-window algorithm was used for temperature change prediction. The results show that the temperature of the seawater in the area has increased by approximately 3～7℃ since operations began at the power plant.
