[Abstract]:Based on the domestic GF-2 and ZY-3 satellite data and taking the southern foot fault of Hashi Mountain in Haiyuan fault zone as an example, comprehensive visual interpretation, three-dimensional interpretation and field verification are used. The application potential of quantitative analysis of domestic high score data in quantitative study of active structure. GF-2 fusion image shows clear phenomena such as fault scarp, left spin fault fault of gully and coearthquake rupture, etc. According to the interpretation results, the south foot fault of Hashi Mountain can be divided into the barren beach and shallot gully section with normal strike-slip type. The left strike-slip Shajiaogou-Yellow River section and the Huanghe Shenjiazhuang section dominated by left-lateral movement have been greatly improved in the 1:50 remote sensing interpretation work along the fault zone in stratigraphic boundary and extraction of detailed information of structural microgeomorphology, etc. The minimum left-lateral displacement of 4.3 m, which reflects the horizontal co-seismic displacement of the Haiyuan earthquake of 1920, and the maximum left-lateral displacement of 333.5 m, reflects the sustained movement of the late Quaternary period. The massive domestic high-resolution satellite data can replace the same resolution data of foreign countries in the quantitative study of active structure in western China, and it has strong application value.
