| Abstract: |
| By adoption of Biolog EcoplateTM system, the analysis of soil microbial community functional diversity was made under 5 kinds of vegetation of Agriphyllum squarrosum, Artemisia sphaerocephala krasch, Caragana korshinskii, Ammopiptanthus mongolicus, and artificial arbor mixed stands of Pinaceae sylvestris L.& Robinia pseudoacacia L.in the desert grassland ecological system so as to probe into the effects of vegetation type on soil microbial community functional diversity.The results showed that the soil microbial community level physiological activity was significantly different (P<0.01) under the 5 kinds of vegetation.The difference was also significant in utilization of carbon substrates in the Biolog EcoplateTM.Amino acids, carbohydrates and carboxylic acids were the main carbon sources to the soil microbial community.After 96 h inoculation of Biolog Ecoplate, soil microbial community diversity showed that the differences of richness (R) and evenness (EH) in utilization of carbon substrates in soil microbial community under the 5 kinds of vegetation were significant (P<0.01) , respectively, except for Shannon-Weinner index (H′) . |
