Soil organic carbon fractions included microbial biomass carbon (MBC), dissolved organic carbon (DOC), and labile organic carbon (LOC), which was investigated over a 0-20 cm depth profile in three types of wetland in Hongze Lake of China. Their ecoenvironmental effect and the relationships with soil organic carbon (SOC) were analyzed in present experiment. The results showed that both active an...

The Tumen River Basin, located in the cross-border region of China, North Korea, and Russia, constitutes an important ecological barrier China. Forest here is mainly distributed around wetland, with distribution wetland having potential to regulate regional forest carbon storage. However, spatially explicit map aboveground biomass (AGB) impact drivers, i.e., climate, still lacking. We thus use ...
