Abstract

To investigate annual variation in soil respiration (R_S) and its components [autotrophic (R_A) and heterotrophic (R_H)] in relation to seasonal changes in soil temperature (ST) and soil water content (SWC) in an Abies holophylla stand (stand A) and a Quercus-dominated stand (stand Q), we set up trenched plots and measured R_S, ST and SWC for 2 years. The mean annual rate of R_S was 436 mg CO₂ m^-2 h^-1, ranging from 76 to 1,170 mg CO₂ m^-2 h^-1, in stand A and 376 mg CO₂ m^-2 h^-1, ranging from 82 to 1,133 mg CO₂ m^-2 h^-1, in stand Q. A significant relationship between R_S and its components and ST was observed over the 2 years in both stands, whereas a significant correlation between R_A and SWC was detected only in stand Q. On average over the 2 years, R_A accounted for approximately 34% (range 17-67%) and 31% (15-82%) of the variation in R_S in stands A and Q, respectively. Our results suggested that vegetation type did not significantly affect the annual mean contributions of R_A or R_H, but did affect the pattern of seasonal change in the contribution of R_A to R_S.
