摘要：Soil enzyme stoichiometry has been proposed to reflect microbial resource limitation. However, this viewoverlooks the profound variations in microbial community composition and soil abiotic properties that may alsoaffect enzyme stoichiometry. In successional subalpine ecosystems after glacier retreat, we found that the stoichiometryof soil carbon-, nitrogen- and phosphorus-acquisition enzymes was strongly associated with the microbialcommunity composition. Soil abiotic properties (pH and soil organic matter quality) may also affectenzyme stoichiometry directly, or indirectly through microbial community composition. In contrast, microbialresource status was weakly related to enzyme stoichiometry. Thus, precautions should be taken when usingenzyme stoichiometry as an indicator of microbial resource limitation. The close relationship between microbialcommunity composition and enzyme stoichiometry suggests that genetic potential is linked to the enzyme activityin subalpine soils.
