Abstract:In this pape,r the chronosequence approach was adopted. Three siteswere selectedw ith pine(P inus tabulaeform is) plantations along the restoration chronosequences (15a (PF15 ), 25a (PF25 ), 30a (PF30 )), and native shrub communities ( uercus aliena var. acuteserrata, respective ly, and Corylus heterophy lla )w ere chosen as re ference. The objective o f this study was to investigate the dynam ics of soil m icrobial biom ass C, N, and soil physico-chem ical properties along the restoration chronosequences. In addition, the correlation between soil m icrobial properties and physico-chem ical properties were exam in
