摘　　要：选取2016-02-08的CBERS-04热红外数据,采用普适性单通道温度反演算法对田湾核电站附近海域的海水温度进行反演。将CBERS-04星反演结果与同时过境的MODIS温度反演结果及相似条件下的Landsat-8和HJ-1B温度反演结果进行对比分析。依据温度反演结果,分析了海温空间分布特征,探讨核电站对周围海域海水温度的影响。研究结果表明,CBERS-04星热红外数据与同时过境的MODIS数据反演得到的海表温度空间分布一致,线性相关性显著;MODIS数据因空间分辨率小,无法对核电周边海域进行有效监测;CBERS-04星可监测核电周边9个级别的热影响区,与相似潮汐状态和气象条件下的Landsat-8和HJ-1B具有相似的热影响级别、规模和空间分布特征,满足核电温排水的监测需求。Based on the infrared data of CBERS-04 on February 8 2016,we used the universal single window temperature inversion algorithm to monitor the distribution of surface temperature and thermal discharge in the sea region near Tianwan nuclear power plant,Lianyungang City,Jiangsu Province.And then,we compared the retrieval results of CBERS-04,MODIS,Landsat8 TIRS and HJ-1 B IRS,analyzed the spatial distribution of the sea surface temperature,and discussed the influence of nuclear power plant on the seawater temperature in the surrounding water based on the retrieval images.The results show that there is a high consistency between the sensors of CBERS-04 and MODIS.The infrared data of CBERS-04 can monitor thermal impact area with 9 levels higher than environmental temperature,which has similar levels,scales and spatial distribution with Landsat-8 TIRS and HJ-1 B,which can satisfy the needs of the thermal discharge monitoring.
