摘要

Kalimantan peatland spans ～5.9million ha (-11% of Kalimantan's total terrestrial land area) as a part of Indonesian peatlands, covers～21 million ha, contains～57.8 Gtof terrestrial carbon. Land cover change of peatland forest results in significant sources CO2 emissions. Thus, we identified to estimate carbon emissions generated by crop land and ex burnt activities in Kalimantan's peatlands degraded forest.Soil CO2 respiration was measured under four of the most prominent land cover and annual agricultural crops on 4-5 year post fire (fern, corn, pineapple) and newly burnt areas in West Kalimantan peatlands. Measurements were obtained from Licor 8100 and gatheredby monthly assessments. Among the land cover types showed different meanmonthly CO2 fluxes. Soil CO2 respiration on newly burnt peatland, pineapple plantation and fern covered showed the highest and not significantly different among them. Cornsmall-scale plantation soil respired the lowest and significantly different from the other three land covers. Dry vs. rainy month comparisons show huge different (>50%) monthly CO2 fluxes rate. Each land cover type has distinctive peat environmental factors that significantly affect CO2 respiration. The result indicates that each crop/cover types generate different level site factors, which affect different level of peat CO2 rates. The regression models of site factors measured for each specific land cover can be applied to obtain better estimate CO2 respiration rates of degraded peatland and agricultural crop cover types. Moreover, it is able to be applied as a baseline for degraded peatland management and CO2 emission mitigation.
