Abstract  

In the Gurbantunggut Desert, seasonal variations of microbial biomass and soil enzymes were measured with 60 soil samples collected from the inter-dune of the sand dune. The results indicated that: significant seasonal differences were observed in microbial biomass and the activity of invertase, alkaline phosphatase, urease, polyphenol oxidase, peroxidase of biological soil crusts. The changing trends of microbial biomass N in different season was spring>summer>autumn>winter; the value of microbial biomass N reached the highest point in March; two peaks were found for the invertase activity in a year; invertase activity was higher from April to September than in the other months and was the highest in April; the changing trends of alkaline phosphatase, urease, polyphenol oxidase, and peroxidase acitivity all presented single-peaked curve and their highest values were observed in different month from March to July; organic matter and total N of the soil in March and September were higher than in the other months; microbial biomass N was significantly and positively correlated with alkaline phosphatase activity and urease activity, respectively; significant positive correlations were observed between soil temperature and invertase, polyphenol oxidase, peroxidase acitivity; soil moisture was significantly correlated with invertase, urease and peroxidase activity; increasing microbial biomass offered substrate or energetic substance for urease and alkaline phosphatase activities and then increased enzymatic activities; the seasonal change of soil enzyme may be impacted by direct roles and indirect roles of soil moisture and temperature.
