In the previous study of the Anhui segment of Tanlu fault zone, it is generally believed that the Anhui segment of Tanlu fault zone is composed of the Wuhe-Hefei fault, the Shimenshan fault, the Chihe-Taihu fault and the Jiashan-Lujiang fault. However, there is no comprehensive and systematic research on the exact boundary position of the fault zone, especially the boundary of the Dabie Mountain in the southern part of the Anhui segment of the Tanlu fault zone. In view of such a situation, based on the multi-source data such as Landsat 8 OLI, ZY-3 and DEM data, the authors comprehensively utilized GIS spatial analysis and spatial statistics to perform remote sensing interpretation of the Anhui segment of Tanlu fault zone and statistical analysis of the interpretation results. The analysis shows the more accurate boundary range of the Anhui segment of Tanlu fault zone. The existing geological data prove that the boundary range is reasonable and reliable to some extent. The study shows that the spatial distribution characteristics of the north and south sections of the Anhui segment of Tanlu fault zone are different. The average trend of the northern section is about N23.5°E, the average width is about 25.99 km, the average trend of the southern section is about N34.9°E, and the average width is about 38.38 km, the overall trend of the whole Anhui segment of Tanlu fault zone is about N33.3°E, with an average width about 30.35 km. The fault zone presents a spatial distribution pattern of “short in the north and long in the south”, “ wide in the south and narrow in the north” and “the fault trend progressively moving northward from south to north”. The research results can provide an important reference for urban planning, engineering construction and geological disaster prevention within the Anhui segment of Tanlu fault zone.
