英文摘要 | Decomposition of soil organic carbon (soc) is a critical component of the global carbon cycle, and accurate estimates of soc decomposition are important for forest carbon modeling and ultimately for decision making relative to carbon sequestration and mitigation of global climate change. we determined the major pools of soc in four sites representing major forest types in china: temperate forests at changbai mountain (cbm) and qilian mountain (qlm), and sub-tropical forests at yujiang (yj) and liping (lp) counties. a 90-day laboratory incubation was conducted to measure co2 evolution from forest soils from each site, and data from the incubation study were fitted to a three-pool first-order model that separated mineralizable soil organic carbon into active (c-a), slow (c-s) and resistant (c-r) carbon pools. results indicate that: (1) the rate of soc decomposition in the sub-tropical zone was faster than that in the temperature zone, (2) the c-a pool comprised similar to 1-3 % of soc with an average mean residence time (mrt) of 219 days. the c-s pool comprised similar to 25-65% with an average mrt of 78 yr. the c-r pool accounted for similar to 35-80% of soc, (3) the yj site in the sub-tropical zone had the greatest c-a pool and the lowest mrt, while the qlm in the temperature zone had the greatest mrt for both the c-a and c-s pools. the results suggest a higher capacity for long-term c sequestration as soc in temperature forests than in subtropical forests.
