主　　题：Forested wetlands Community-level physiological profiles(CLPP) Carbon metabolism diversity Soil enzymatic activity Seasonality 

摘      要：This study explores the effects of vegetation and season on soil microorganisms and enzymatic activity of different wetlands in a temperate *** carbon metabolism diversity was assessed using community-level physiological profiles(CLPP)with 31 different carbon *** indicated that significant interactions occur during carbon substrate metabolism of the ***,the different types of vegetation present in the wetland ecosystem combined with the seasonal effects to influence microbial carbon metabolism and enzymatic *** most significant differences occurred to carbohydrates,carboxylic acids,and amino *** Mantel test confirmed positive correlations between soil enzymatic activities and microbial carbon *** microorganisms in Betula ovalifolia and Carex schmidtii wetlands used carbon substrates more efficiently in summer than those in other forested wetlands during other *** activities also showed a similar trend as microbial carbon *** results demonstrate that microbial carbon metabolism patterns can be used as biological indicators in wetland ecological alterations due to vegetation type or to seasonal factors.
