核电站温排水遥感监测方法研究——以田湾核电站为例

A Research on the Remote Sensing Monitoring Method with the Thermal Discharge of Tian-Wan Nuclear Power Station

以江苏省连云港田湾核电站为主要研究区,通过热红外遥感技术研究温排水热污染现象,综合应用美国Landsat卫星热红外波段数据及地面气象测站资料,定量反演核电站建成前后附近海域水温分布与变化情况。研究结果表明,遥感技术完全能够满足温排水监测要求,对于完善近岸海域生态环境保护工作具有积极意义。

Based on the Landsat5 TM images and weather data, the research was carried on monitoring the thermal discharge of Tian-wan nuclear power station with a remote sensing method. After inversing through the thermal infrared remote sensing data, the water surface temperature information was abstracted by the mono-window algorithm. And then, different situation about thermal discharge intensity, diffuse-range and environmental influence was discussed. The result shows that remote sensing technology could meet the requirements of nuclear power station monitoring quite well.
