| 中文摘要: |
| 以杭州湾海域和连云港周边海域为研究对象，基于Landsat-5、Landsat-9的多光谱和热红外数据，对研究区的海域岸线和温度场信息进行提取，分析海域岸线变迁和温度分布变化特征。结果显示，研究区的海域岸线变化均较显著；海域温度在核电站运行前较为均匀，无明显温度分异，核电站运行后，因温排水排放，核电站周边海域温度出现明显分异；Landsat-9热红外数据温度反演结果可靠，可用于监测温排水对海域环境的影响。 |
| 英文摘要: |
| Taking Hangzhou Bay area and the surrounding waters of Lianyungang as the study objects， based on multispectral and thermal infrared data from Landsat-5 and Landsat-9，the coastline and temperature field information in the studied area were extracted，and the variation characteristics of coastline and temperature distribution were analyzed. The results showed that the coastline in the study area changed significantly. The temperature in the sea area was relatively uniform before the operation of the nuclear power plant， and there was no obvious difference in temperature. After the operation of the nuclear power plant， the temperature in the sea area around the nuclear power plant was obvious different due to the discharge of warm water. The temperature inversion results by Landsat-9 thermal infrared data were reliable and could be used to monitor the impact of warm discharge on the marine environment. |
