Abstract

To characterize soil black carbon storage and distribution in Zhejiang Province，China，litter，surface soil（0 － 10 cm），and subsurface soil（10 － 20 cm） samples were collected from forest soils at 60 sites with or without wildfire histories. Results showed that mean content of black carbon in litter，surface soils and subsurface soils were 3.96，6.91，and 3.39 g·kg-1，in that order，accounting for 0.96%，8.07%，and 11.82% of the soil total organic carbon，respectively. From 40 sites experiencing fire events within the last 40 years，black carbon in the litter and 0 － 10 cm soils was significantly higher than soils without a record of fire （P＜0.05），whereas in the 10 － 20 cm soils fire events had no major impact on black carbon content（P＜0.05）. On slopes，accumulation of black carbon was generally higher on the lower part compared to the top and upper part. In soil developed from residual deposits，proportion of black carbon in total organic carbon was greater in the 0 － 10 cm layer and decreased significantly with increasing profile depth（P＜0.05）. However，in soil developed from slope deposits，high black carbon levels were noted in 30 － 80 cm，and the proportion of black carbon in total organic carbon increased significantly with increasing depths（P＜0.05）. Content of black carbon in clay fractions was higher than that of non-clay fractions，and size of soil black carbon particles became smaller with increasing depth.［Ch，5 tab. 14 ref.］
