The effect of land remediation on Carbon balance in tropical peat area

通过对泰国南部热带泥炭区的研究，得出以下结论：(1)土壤温度日变化对泥炭日平均分解速率的影响小于6%。这一事实表明，一年内的碳排放量可以通过日平均气温来估算。(2)浅层条件下，泥炭分解速率随地下水位的增加而增加。然而，在地下水位50厘米以下，这种速率几乎是恒定的。(3)东南亚不同地区泥炭土的潜在分解率表现出相似的热特征，最大差异约为40%。

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%.
