Abstract

The relationships of CO2 emission with water table, peat moisture and humification was studied in secondary peat swamp forest floor at the Vodoi national park, Vietnam in order to propose a better water management
system to maintain forest growth and restore peat. The recent artificially maintained high water level in the forest floor for most of the year in order to reduce risks of fire has led to bad growth of forest and death of some plants. The results of this study showed that the less humified top 10 cm peat (litter) layer has a major contribution to CO2 emission from peat surface. The CO2 release rate from peat oxidation decreased significantly when peat moisture became less than 80% of the water holding capacity. Deep water level in dry season, lower than 25 cm under the peat surface, might decrease the rate of CO2 emission from peat oxidation and is good for forest-root respiration. Therefore, artificially maintaining a high water level in the dry season is not a good choice to restore peat and forest in the Vo Doi National Park.
