科学评估区域森林碳储量动态与增汇潜力对理解陆地碳循环具有重要的意义。本文基于生物量转换因子连续函数法，对西双版纳1993—2006年间森林植被碳储量与碳汇潜力进行了研究，结果表明，（1）西双版纳1993—1994年间森林植被整体碳储量为60 770 378.37 t，碳汇增量表现为栎类(Quercus L.)>经济林>思茅松(Pinus kesiya)>其它阔叶>桤木(Alnus cremastogyne)，主要森林类型的碳密度范围为15.08~74.76 t·hm~(-2)；2005—2006年间森林植被整体碳储量为62 347 715.19 t，比1994—1993年间上升2.60%，碳汇增量均表现为其它阔叶>经济林>栎类>思茅松>桤木>杉木(Cunninghamia lanceolate)>其它针叶，主要森林类型的碳密度范围为8.60~70.90 t·hm~(-2)。（2）2005—2006年间，景洪森林植被整体碳储量为23 299 801.23 t，碳密度范围为8.78~73.35 t·hm~(-2)；勐海森林植被整体碳储量为14 058 043.42 t，碳密度范围为7.95~59.51 t·hm~(-2)；勐腊森林植被整体碳储量为25 050 562.32 t，碳密度范围为8.46~98.73 t·hm~(-2)。可见，1993—2006年间，西双版纳森林植被起到了重要的碳汇功能，且其碳汇功能呈上升趋势。 |

To evaluate forest carbon stock dynamics and carbon sink capacity of regional forest scientifically is of great significance to terrestrial carbon cycle.Based on the method of biomass expansion factor function,this paper studied forest carbon stock dynamics and carbon sink capacity of Xishuangbanna in the period of 1993-2006,and the results showed that,(1)in the period of 1993-1994,total forest vegetation carbon stock was 60 770 378.37 t.Carbon sink increment all ranged as oak forest>production forest>pinus khasys>other broad leaved forest>alder forest,and carbon density of main forest type was 15.08~74.76 t·hm~(-2).In the period of 2005-2006,total forest vegetation carbon stock was 62 347 715.19 t,which increased by 2.60%compared with the period of 1993-1994.Cink increment all ranged as other broad leaved forest>production forest>oak forest>pinus khasys>alder forest>fir forest>other needle forest,and carbon density of main forest type was 8.60~70.90 t·hm~(-2).(2)In the period of 2005-2006,total forest vegetation carbon stock of Jinghong was 23 299 801.23 t,and carbon density of main forest type was 8.78~73.35 t·hm~(-2).Total forest vegetation carbon stock of Menghai was 14 058 043.42 t,and carbon density of main forest type was 7.95~59.51 t·hm~(-2).And total forest vegetation carbon stock of Mengla was 25 050 562.32 t,and carbon density of main forest type was 8.46~98.73 t·hm~(-2).Undoubtedly，forest vegetation in Xishuangbanna played an important role in carbon sequestrating,and the effect of carbon sink had been in rising trend during the year of 1993-2006. |
