【摘要】 本文从丰润—丰台镇线性卫星影象与相应地表地貌、地质、植物等的对应关系出发,探讨了隐伏活动断裂在卫星影象上的表现机制。丰润—丰台镇断裂的新构造活动造成两盘第四系厚度的较大差异;并使相应地表地形线性起伏,由此而引起地表水系、植物类型等分布上的差异,最终表现为线性影象。作者认为,与构造有关的线性影象并非由深部的断裂信息透视出来,也非由地面的微观差异显示出来,而是由于传感器“聚敛”了与构造有关的地面宏观异常,间接的显示而成。更多还原

【Abstract】 Based on the relation ship of its linear landsat image and the field features on geology,geomorphology,vegetation,etc.this paper discusses the mechanism of appearance of Fengrun-Fengtai concealed active fault on landsat image.The new tectonic activities of the fault has caused great difference of the thicknesses of Quaternary sediments at two sides,and hence the differences of the distribution of drainage system and vegetation type,and eventually the linear appearance.It is thus considered that the tectonically-related linear image is neither the reflection of deep seated fracture nor the gathering of surface microdifferences,but is an indirect display of the surface tectonic macro-anomalies collected by landsat sensors.更多还原
