Abstract
Understanding the age effect on soil carbon balance in forest ecosystems is important for other material cycles and forest management. In this research we investigated soil organic carbon density, litter production, litter decomposition rate, soil respiration, and soil microbial properties in a chronosequence of four Chinese fir plantations of 7, 16, 23 and 29 years at Dagangshan mountain range, Jiangxi Province, south China. There was a significant increasing trend in litter production with increasing plantation age. Litter decomposition rate and soil respiration, however, declined from the 7-year to the 16-year plantation, and then increased after 16 years. Th...
