Abstract: The physical and chemical properties, soil microorganisms and enzyme activities in five patterns of vegetation rehabilitation were studied. The soil microorganisms, enzyme activities and the content of organic matter and total N of five patterns increased evidently than in control site. The amount of total microorganism rankedas burned shrub﹥Robinia pseudoacacia ﹥mixed stands of Pinus elliottii and Robinia pseudoacacia﹥Cyclobalanopsis glauca﹥Pinus elliottii﹥control site. The enzyme activity was different in five patterns. The content of urease in the surface layer soil ranged as burned shrub﹥Cyclobalanopsis glauca﹥Robinia pseudoacacia ﹥Pinus elliottii﹥mixed stands of Pinus elliottii and Robinia pseudoacacia﹥control site,and the invertase as burned shrub﹥Pinus elliottii﹥Cyclobalanopsis glauca﹥Robinia pseudoacacia ﹥mixed stands of Pinus elliottii and Robinia pseudoacacia﹥control site.The diversity of catalase is not significantly different in five patterns.

Key words: vegetation rehabilitation, soil microorganism, soil enzyme activity, physical and chemical property, upper reaches of Jialingjiang River
