Turnover of Wetland Sediments On Mineralization of Carbon, Nitrogen and Phosphorus.

Sediments in situ monitoring and incubated under controlled environment in growth chambers with different temperatures from various vegetation origins were conducted. Respiration rates of the sediments were monitored by trapping released CO₂ with N_aOH, analyzed by LiquiTOC and also solution samples were collected in certain intervals to evaluate the influences of vegetation types, temperature regimes, and naturally dynamic moisture changes on the respiration and sediments mineralization in order to elucidate the pool and/or sink role of wetland and its determinant factors to impact the wetland organic carbon sequestration.
