Abstract: The WNW-trending Changping-Fengnan buried active fault on the southern margin of Yanshan Mountain is clearly identified on the Landsat images as a dark bandlike linear imagery several kilometers wide. This imagery was produced under a specific climatic condition due to the slight difference of loose sediment of watery zone and its adjacent area in density represented by reflective electromagnetic wave spectra on the imeges. And the watery zone was formed with the migration of ground water along the active fault and ascension on ground surface.By analyzing geological and geophysical data, it has been proposed that Changping-Fengnan buried active fault might be formed during the late Mesozoic time. This was a crustal fault, characteristic of dextral slip, that has dissected the Conrad and the Moho discontinuity since Quaternary.

摘要： 在特定气候条件下获得的陆地卫星图象上,深色、带状的线性影象,反映出昌平-丰南隐伏活断层的形迹。这是向断裂带运移的地下水沿活动构造带上升到地表、在卫星图象上由高密度值显示出来的,是基底构造活动在地表的反映。据地质、地球物理资料分析,昌平-丰南隐伏活断层可能是中生代末期形成的,断开康氏面和莫氏面的壳型断裂,第四纪以来具有左旋滑动的特征。本活断层是一条重要的地震活动带。
