%X Vegetations recovery is a key measure to improve eco-environments in the Chinese Loess Plateau.In order to find the effect of soil microbial biomass under different vegetation restoration in this region,six long trial sites located in Zhifanggou Catchment were studied.The results showed that soil microbial biomass,microbial respiration and physiochemical properties increased apparently.After 30 years of de-farming and vegetation recovery,soil microbial biomass C,N,P(SMBC,SMBN,SMBP)and microbial respiration,respectively,increased by 109.01%-144.22%,34.17%-117.09%,31.79%-79.94% and 26.78%-87.59% as compared to the farmland.However metabolic quotient declined dramatically with a percentage decrease of 57.45%-77.49%.Different types of vegetation restoration are differentin improving soil properties.In general,mixed stands of P.tabulaeformis-Amorpha fruticosa and R.pseudoacacia-A.fruticosa had the most remarkable effect,followed by Robinia pseudoacacia and Caragana korshinkii,while fallow land and Pinus tabulaeformis was the smallest.Construction of mixed forest is more effective than that of pure forest in restoring vegetations on the eroded hilly Loess Plateau.The significant relationships were observed between SMBC,SMBP,microbial respiration and physiochemical properties of soil.We think that microbial biomass can be used as indicators of soil quality.
