为研究潮汐变化对连云港田湾核电站邻近海域温排水时空分布与变化规律的影响,利用Landsat-8热红外数据,构建基于劈窗算法的温度反演模型,结合潮汐数据分析田湾核电站邻近海域的温排水分布规律。得出结论:基于Landsat-8数据的劈窗算法温度反演模型应用在田湾核电站邻近海域温排水的监测效果较好;潮汐运动直接影响田湾核电站温排水的时空分布与扩散方向,并呈现一定的规律性。本文的研究方法为核电站温排水常规性监测提供了一定的技术参考。

In order to study the influence of tidal changes on the spatial and temporal distribution and variation law of the temperature and drainage in the adjacent sea area of Lianyungang Tianwan nuclear power plant,a temperature inversion model based on splitting window algorithm was constructed by using Landsat-8 thermal infrared data,and the distribution law of the temperature and drainage in the adjacent sea area of Tianwan nuclear power plant was analyzed by combining tidal data.It is concluded that the temperature inversion model based on the data of Landsat-8 based on the wedge window algorithm has a good monitoring effect on the temperature drainage in the adjacent sea area of Tianwan nuclear power plant.Tidal movement directly affects the spatial and temporal distribution and diffusion direction of the thermal drainage of Tianwan nuclear power plant,and presents certain regularity.The research method in this paper provides some technical references for the routine monitoring of thermal drainage in nuclear power plants.
