Analysis of Marine Environment Change Based on Remote Sensing Monitoring
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.
