摘要： Landsat系列卫星热波段具有60~120m的空间分辨率，对各种环境监测起到了重要的作用。随着Landsat系列卫星在全球范围内地表温度（land surface temperature，LST）产品的发布，其验证工作也随之展开，然而对于长时间序列的精度验证工作仍然缺乏。以黑河流域中游为研究区，利用研究区内湿地站（SD）、戈壁站（GB）和大满超级站（CJZ）三个气象站的地面测量数据对2013-2016年清晰无云的31景Landsat 8地表温度产品进行了验证与分析，并将Landsat 8地表温度产品与广泛使用的普适性单通道算法（JMS）反演结果进行了对比。结果表明，Landsat 8地表温度产品与普适性单通道算法反演结果精度均较高，在各个站点处R2均优于0.949。基于所有站点分析，Landsat 8地表温度产品精度稍高于普适性单通道算法反演结果。

Abstract: The thermal band of Landsat series satellites has a spatial resolution of 60-120m,which plays an important role in various environmental monitoring.With the release of land surface temperature (LST) product of Landsat series satellites worldwide,the validation work also begins.However,there is still a lack of validation for long time series.Taking the middle reaches of the Heihe River Basin as the study area,the Landsat 8 LST product with 31 clear and cloudless scene images from 2013 to 2016 were verified and analyzed by using the ground measured data observed by the three weather stations of Wetland Station (SD),Gobi Station (GB) and Daman Super Station (CJZ),and the Landsat 8 LST product was compared with the widely used single-channel algorithm (JMS) inversion results.The validation results show that the accuracy of both the Landsat 8 LST product and the JMS inversion results are high,and R2 at each site is better than 0.949.Based on the analysis of all sites,the accuracy of Landsat 8 LST product is slightly higher than the JMS.
