摘　　要：应用NOAA卫星1km分辨率的热红外遥感影像，研究了阿尔金断裂的线性特征，结果表明：断裂两盘色调反差巨大，断裂两侧地形切割程度强烈。其中断裂西段的色调反差大于东段，间接证明断裂西段的活动性强于东段；年周期尺度上断裂带的红外辐射亮温与数字高程模型（DEM）数据的对比反映，断裂北侧的像素平均亮温值高于南侧5～8K，且与地形保持良好的负相关性。By use of the thermal infrered image with the resolution of 1 km the linear fecture of Mtyn fault is studied. The results show that the picture contrast between two walls of the faults is large and the topographic dissection degree on the fault sides is strong. In addition, the contrast in the west section is larger than that in the east section, it proves that the activity of the west section is stronger than that in the east one, and the comparison between the infrared radiation brightness temperature in the fault and the data of the DEM in an year period reflectes that the mean brightness temperature of the pixels of the northern side is 5 - 8 K higher than that of the southern side and keeps a good negtive correlation to the topography.
