In order to evaluate the environmental effect of tropical peat-land development on the carbon dioxide emission, field survey was conducted at Bacho Swamp site area in Narathiwat, Thailand. Laboratory experiments were also conducted to estimate the carbon dioxide emission under different water condition in the peat-soil.The peat-soil volume at the Bacho Swamp was estimated using indicator geostatistics. The estimated total peat-soil volume within the investigation boundary at the Bacho site is 2.14*10^7 m^3. Using the average organic carbon content value measured at the site, the total organic carbon storage is estimated 2.5_10^6 tC.The carbon dioxide emission from peat-soil under drained condition is estimated 38tC/ha/yr and 19tC/ha/yr by forest fires and aerobic decomposition, respectively. On the other hand, the emission is estimated 2tC/ha/yr and 1.2tC/ha/yr under insufficient drained condition and water logged condition, respectively.As a result, the carbon dioxide emission from developed tropical peat-land ia evaluated to change in the range of 57tC/ha/yr to 1.2tC/ha/yr by the water management at the site.

为了评估热带泥炭地开发对二氧化碳排放的环境影响，在泰国那拉提瓦府的巴乔沼泽遗址区域进行了实地调查。还进行了实验室实验来估算泥炭土中不同水分条件下的二氧化碳排放量。巴乔沼泽的泥炭土体积是使用指示地质统计学估算的。 Bacho 地点调查边界内的估计泥炭土总体积为 2.14*10^7 m^3。根据现场测量的平均有机碳含量值，估算总有机碳储量为 2.5_10^6 tC。排水条件下泥炭土的二氧化碳排放量估算为 38tC/ha/yr 和 19tC/ha/yr，分别由森林火灾和好氧分解造成。另一方面，在排水不足和积水条件下，排放量预计分别为2tC/ha/yr和1.2tC/ha/yr。因此，通过现场的水管理，发达热带泥炭地的二氧化碳排放量估计变化范围为57tC/ha/yr至1.2tC/ha/yr。
