Abstract: The following problems are presented in this paper. The remote sensing geological methods are used to process and interpret remote sensing information for the middle of Tancheng-Lujiang fault zone, the distribution of main faults in the region, especially the faults in cryptic fields and some transcurrent faults which are approximately perpendicular to the main faults.The results which are essentially in conformity with the field works, are achieved by processing the satellite tapes using the method of enhanced high-pass fittering. Some useful data are derived from also essential phenomena analysis of active faults and measurement of apparatuses.We have established the preliminary interpreting marks of active faults in the region after interpreting the layer and tectonics and examining them in field works.The surface distribution of the faults in the region, including the situation of the transcurtent faults and the characteristics of the active faults, are clearly shown in Fig.2, which illustrates also the characteristics of the active faults from north to south.

摘要： 本文采用数字图象增强处理、数据测定及目视解译等方法,研究郯庐断裂带中段的遥感信息。研究结果是:1.建立了区域活动断裂解译标志,从而得知,本区东部两条主断裂的地面平面展布,南部以右列形式为主,北部主要表现为左列,中部为平行破裂;2.影象上可识别出临沂—郯城地区有四条隐伏的北北东向主断裂及若干条切割主断裂的北西—北西西向断裂。郯庐断裂带中段显示了一些纵向差异性;3.高通滤波处理对本区隐伏构造的影象显示较为有效。
