Abstract:As a collision orogenic belt, Dabie mountain is between the Yangtze and North China blocks. To calculate integrally the rate field of Dabie mountain, we use linear deformation models based on leveling observation data in 1980, 2005 and 2015. Our research shows that: Huaihe plain ground is subsiding due to drawing groundwater; Dabie mountain is lifting as caused by inheritance movement; Yangtze river valley is also dominated by inheritance movement; and the southern segment of the Tanlu fault is in the stage of strain accumulation. Preparation for a potential earthquake should be undertaken.
