文章以红沿河核电基地周围海域为研究区，利用 Landsat-8热红外遥感影像（thermal infrared sensor，TIRS），分别对辐射传输方程法、单窗算法、普适性单通道法和 Qin 劈窗算法等四种算法进行海表温度反演模型参数修订与数据处理。通过与实际观测温度数据进行精度验证与比对分析，寻求基于Landsat-8/TIRS 数据的区域最佳温度反演算法。结果表明，辐射传输方程法均方根误差在1K 以内，反演精度最高；Qin 劈窗算法次之，均方根误差达到3K 左右，反演精度较差，整体反演温度偏高；单窗算法和普适性单通道法均方根误差高于3K，反演精度最差，整体反演温度偏低。辐射传输方程法可作为红沿河核电海域温排水遥感监测首选算法。

Based on the images from Landsat-8 thermal infrared sensor in the study area of Hongyanhe nuclear power station, this paper presents a novel approach to revising and data-processing the parameters of sea surface temperature retrival model for the thermal radiative transfer equation algorithm, mono window algorithm and general applicability of single channel algorithm and Qin split window algorithm respectively. The results are compared with the actual measured temperature data for accuracy verification and comparison analysis to seek the best temperature retrieval algorithm in the study area based on the Landsat-8/TIRS data. The results show that the root mean square error of the thermal radiative transfer equation algorithm is within 1K, its retrieval accuracy is the best of all. Qin split-window algorithm is the second one, but its retrieval precision reaches about 3K, retrieval accuracy is worse, and the overall retrieval temperature is also very high. The retrieval precision of the mono-window algorithm and generalized single channel exceeds 3K, its retrieval accuracy are the worst of all, and the overall retrieval temperature are very low. So radiative transfer equation algorithm can be used as the preferred algorithm for Hongyanhe nuclear power plant thermal discharge monitoring.
