英文摘要	Large quantities of forest products globally have been lumbered, resulting in widespread conversion from primary forests [PFs] to secondary forests [SFs]. This transformation has exerted important impacts on the global carbon [C] cycle. Therefore, it is essential to clarify how soil C, which is a vital component of the global C pool, responds to the converting of forests from PFs to SFs, in parallel to identifying the underlying mechanisms. Here, nine paired (PFs and SFs) soil samples (0-10 cm) were obtained from tropical to cold-temperate zones along the north-south transect of eastern China (NSTEC). The heterotrophic respiration rate [R-H] as per soil organic C at a reference temperature of 20 degrees C [R20-C] and its temperature sensitivity [Q(10)] were measured and calculated through 14 d incubation experiments. Our results showed that most of R-20(-C) and Q(10)( )in SFs were greater than those in PFs. Strong spatial variation in the differences in R-20(-C) and Q(10) between PFs and SFs [Delta R-20(-C), Delta Q(10)] was observed along the NSTEC, with the greatest Delta R20-C, Delta Q(10) being detected in the soils of mid-latitude forests. Overall, 83.2% of the spatial variation in Delta R20-C was explained by physical-chemical and microbial properties, which contributed 68.5% and 52.4% variation solely, respectively. Similarly, 79% of the variation in Delta Q(10)( )between PFs and SFs was explained by microbial properties, physical-chemical properties, and dissolved organic C, which contributed 81.6%, 10.5%, and 9% variation solely, respectively. Overall, our findings demonstrate high spatial variation in Delta R-H and Delta Q(10 )between PFs and SFs, which was mainly explained by microbial properties of soils.
