摘要：

Soil respiration (R-s) is overwhelmingly the sum of autotrophic respiration (R-a, root and rhizosphere) and heterotrophic respiration (R-h, microbes and soil fauna). Separating R-s into R-a and R-h components is a major challenge but necessary for understanding the implications of environmental change on soil C cycling and sequestration. In this study, a trenching method was employed to partition R-s sources in Chinese fir plantations in Southern China. Soil CO2 efflux (FCO2) rates were measured using an infrared gas analyser system with soil chambers at the trenched and untrenched (Control) p...
