英文摘要	In order to evaluate the ecological consequences and potential mechanisms of specific C compounds on soil microbial processes under climate warming, we injected solutions of two modelled root exudates, 2, 6-di-tert-butyl-4-methylphenol (BHT) and 1, 2-benzenedicarboxylic acid, dibutyl ester (DBP), respectively, into soil at two concentrations (20 and 1000 mu gg(-1) soil). For all treatments, soils amended with the two phenolic compounds were incubated at two temperatures (20 degrees C and 30 degrees C) for 30 days. The responses of soil enzyme activity and microbial property to modelled root exudates to some extent depended on temperature regime, exudation component, and addition concentration. For example, the addition of BHT tended to decrease the soil enzyme activities. However, DBP addition generally increased the two metabolic enzyme activities at 30 degrees C, and tended to decrease the two enzyme activities at 20 degrees C, but a significant reduction was observed only at a high concentration at 20 degrees C. The microbial biomass and enzyme activity were generally lower at 30 degrees C compared to those at 20 degrees C, when averaged across all treatment combinations. Taken together, our results indicated that the amounts and quality of liable root-derived C can differentially affect microbial processes, and various environmental changes will greatly complicate root-microbe-soil interactions in forests.
