| 摘 要： | 利用贵州省2000-2007年各类退耕还林面积和树种数据，设定了2008～2010年间的4种年度造林面积情景。再依据贵州省森林资源清查中不同树种的的历史数据和生长参数建立生长方程，并结合生物量扩展系数、木材密度和碳含量等参数，预测出贵州省未来50年不同情景下的退耕还林主要树种树生物质碳储量及变化。结果表明在2010、2020、2030、2040、2050年，6大造林树种的总碳储量分别达到4．54～4．82TgC、11．02～13．47TgC、14．77～18．92TgC、10．69～21．83TgC、12．52～23．47TgC，占总退耕还林工程的43％-51％。

| Abstract: | By using the data of area and main tree species of Guizhou province from 2000 to 2007 ,and eight different scenarios have been schemed for the annual area of OGP--forests during 2008-2010 and harvest options. Then base on growth rate of different tree species, the model has been set up, in combination of biomass expansion factors （BEF）, wood density（WD）and carbon fraction（CF）, this paper predicts the living biomass carbon stock and its changes of main tree species under different scenarios during 2010-2050. The results shows that the total carbon stock of six species will be up to4.54-4.82TgC,11.02- 13.47TGC,14.77-18.92TgC,10.69-21.83TgC,12.52-23.47TgC by the year 2010,2020,2030,2040 and 2050, respectively, the biomass carbon stock in the biomass of the six species accounts for 43 - 51% of all GGP in Guizhou province. |
