| Research Abstract |
The following results were concluded after the research in a tropical peat area in southern Thailand.
(1)Diurnal change of soil temperature effects less than 6% of daily averaged peat decomposition rate. This fact imply that carbon emission rate in a year can be e stimate from daily average temperatures.
(2)Peat decomposition rate increases as water table becomes deeper in shallow table condition. The rate, however, is almost constant below 50cm deep in water table.
(3)Potential decomposition rate of peat soil at different places in the Southeast Asia show similar thermal characteristics and the maximum difference of the rate is a bout 40%.
