摘要：Analysis of surface dynamics has the potential to identify areas of recent tectonic activity. By using analytical capability of MATLAB and GIS toolbox in conjunction with digital elevation model (DEM) of 5m spatial resolution, the semi-automated morphometric parameters were extracted to document the influence of neotectonics on landscape evolution in the Emilia-Romagna Apennines, northern Italy. The drainage network and sub-basins of Strahler order 4 and 5 were extracted from DEM and analyzed to demarcate areas of active deformation. The main purpose of this study was the assessment of surface dynamic processes and geotectonic setting of the Secchia, Panaro and Reno mountain river basins. The morphometric parameters such as isobase, incision, surface roughness, drainage basin asymmetry and T-index were extracted to recognize tectonic and/or lithologic control on drainage network development, basin morphology and landscape evolution. The results obtained in this investigation are consistent with the recent tectonic uplift of the region and shows strong positive correlation with the geological structures and neotectonic activity of the study area.
