On the basis of petrology, mineral composition and peak p-T conditions of the eclogites from Taihu area in southern Dabie terrain, the authors hold that southern Dabie Terrain is composed of three metamorphic zones, namely, the ultrahigh pressure zone, the high/ultrahigh pressure ‘mixed' zone, and the high pressure zone, with a regional p-T gradient trend. Five Grt-Cpx thermometers and Grt-Cpx-Phe barometers were used to evaluate the peak p-T conditions of these eclogites. Four p-T regions have been identified, and their metamorphic temperature and pressure decrease gradually from north to south, being 760～950℃, 3.5～4.1 GPa; 660～750℃, 2.7～3.1 GPa; 640～780℃, 2.0～2.7 GPa; and 550～680℃, 1.5～2.3 GPa respectively. These features imply that southern Dabie Terrain was a coherent terrain during the subduction. However, the existence of the pressure gaps between the UHP zone and the HP zone or among adjacent eclogites in different metamorphic zones, the chaotic spatial distribution of eclogites and their relationship with country rocks all demonstrate that southern Dabie terrain was shortened or juxtaposed during the exhumation, and that the present distribution of eclogites represent the status of exhumed eclogites. 
