摘　　要：以阜阳市颍州区、颍泉区和颍东区三区为研究区,利用Landsat 8卫星遥感数据与MODIS Terra卫星产品数据,对大气校正法、Qin_SC、J&M_SC10和TIRS10_SC等4种单窗反演算法进行对比研究,并以阜阳市三区的22个自动气象站温度数据为基准进行反演精度的验证。结果表明,大气校正法和J&M_SC10算法反演误差相对较少,精度较为接近,平均绝对误差分别为0.95℃和0.94℃;Qin_SC和TIRS10_SC算法反演误差较大,平均绝对误差大于2℃。在一定的误差要求下,大气校正法和J&M_SC10算法均可以运用于阜阳市地区的LST反演。Taking Yingzhou District,Yingquan District and Yingdong District in Fuyang City as the research area,using Landsat 8 satellite remote sensing data with MODIS Terra satellite product data,four single window inversion algorithms such as the atmospheric correction method,Qin_SC,J&M_SC10 and TIRS10_SC are compared and studied.Temperature data of 22 automatic weather stations in three districts of Fuyang City are used to verify the inversion accuracy.The results show that the atmospheric correction method and J&M_SC10 algorithm inversion error is relatively small and the precision is relatively close.The average absolute error is 0.95℃and 0.94℃respectively.Qin_SC and TIRS10_SC algorithm and the inversion error is larger and the average absolute error is greater than 2℃.Under certain error requirement,atmospheric correction method and J&M_SC10 algorithm can be used to LST inversion in Fuyang City.
