我们使用土地覆盖图和基于卫星图像的主动火灾检测来评估1990年至2010年东南亚泥炭地森林砍伐的速率和空间分布。在此期间，马来西亚半岛、苏门答腊和婆罗洲的泥炭地森林覆盖率从77%下降到36%。经过20年的大规模森林砍伐（31000 km（2）; 4.9% yr（-1））与火灾活动密切相关，苏门答腊只剩下28%的历史森林泥炭地。如果允许泥炭地森林砍伐以目前的速度继续下去，东南亚的泥炭沼泽森林将在2030年左右消失。这将对依赖泥炭沼泽森林提供的环境服务的当地社区产生严重后果，将导致该地区特有的泥炭沼泽森林物种灭绝，并将增加全球碳排放。
We used land-cover maps and active fire detection based on satellite imagery to evaluate the rates and spatial distribution of peatland deforestation in Southeast Asia from 1990 to 2010. Over this time period, the proportion of forest cover in the peatlands of Peninsular Malaysia, Sumatra, and Borneo fell from 77% to 36%. After two decades of extensive deforestation (31 000 km(2); 4.9% yr(-1)) strongly associated with fire activity, Sumatra has been left with just 28% of its historical forested peatlands. If peatland deforestation is allowed to continue at current rates, the Southeast Asian peat swamp forests will disappear by around 2030. This will have serious consequences for the local communities that rely on the environmental services provided by peat swamp forests, will lead to the extinction of peat swamp forest species endemic to this region, and will contribute to global carbon emissions.
