岸线变迁对田湾核电站温排水影响遥感调查

Remote sensing survey of the influence of coastline changes on the thermal discharge in the vicinity of Tianwan Nuclear Power Station

以田湾核电站周边海域为主要研究对象,选取2组同一潮态下、不同时相的Landsat8数据,研究田湾核电站周边岸线变化及温排水热影响现象,综合分析核电站周边岸线变迁对附近海域水温分布与变化的影响。结果表明,田湾核电站周边海域岸线变化显著,岸线变迁影响温排水水域流场分布,对核电站温排水区域造成影响。遥感技术能够监测出核电站周边岸线变迁情况及其对温排水的影响情况,关注周边岸线变化情况对于核电站周边海域海温监测工作具有积极意义。

Based on the infrared data of the Landsat8 in similar tides and different time spans in the sea region near Tianwan nuclear plant,Lianyungang City,Jiangsu Province,on November 15,2013 and February 27,2017,the authors used remote sensing technology to study the thermal discharge of nuclear power plant and change along the coastal line.The relationship between the thermal discharge and change in the coastal line was analyzed.The results show that the construction of peripheral engineering of Tianwan nuclear power plant dramatically changed the coastline,which affected the size and distribution of the thermal discharge.Remote sensing technology can detect the change of coastal line near the nuclear power plant and its effect on thermal discharge distribution.It is important to monitor the change of coastline near the nuclear power plant for sea temperature monitoring.
