Impact of drainage on peatland soil environments and greenhouse gas emissions in Northeast China.

ABSTRACT: Peatlands are vital for global carbon storage, but drainage significantly disrupts their natural carbon cycling. Drainage alters peatland soil environments in complex ways, affecting factors such as water table, soil temperature, organic carbon (SOC), pH, and microbial communities. However, how these factors interact to influence GHG emissions remains unclear. In this study, we compared water table, soil temperature, soil properties, microbial community structure, and GHG emissions across three zones of a peatland in Northeast China undergoing drainage: drained, transition, and natural areas. The average water table in the drained area was significantly lower than in the natural area (from 11.45 cm to -13.47 cm), shifting from waterlogged to unsaturated conditions.
