摘要:科学评估区域森林碳储量动态、固碳现状及其增汇潜力对理解陆地生态系统碳循环以及源汇功能具有重要意义。利用青海省第三次(1989-1993年)至第六次(2004-2008年)森林资源清查资料,以及不同树种生物量和蓄积量之间的线性关系,对青海省近19年来森林碳储量进行了求和估算。结果表明:①青海省森林面积从1989年的246.5*10~4 hm~2增加到2008年的355.0*10~4 hm~2。②青海省4次森林资源清查中森林植被整体碳储量从1989年的814.34*10~4 t增加到2008年的1118.26*10~4 t,增加了303.92*10~4 t,年均增加(19a)159.96*10~4 t,年均增长率1.68%,表明19年间青海森林植被碳汇作用不断增强,储碳能力将随森林面积的增加逐渐增加,青海省的森林是CO_2的汇。③青海省1989-2008年间主要森林类型碳增汇量为柏木>桦木>杨树>云杉,可见这几种林分类型在全省森林植被碳汇功能中占有重要的地位。如果对现有森林进行更好地抚育和管理,青海省森林作为CO_2汇的潜力很大。

To evaluate forest carbon stock dynamics,carbon sequestration and carbon sink capacity of regional forest scientifically is very important to understand terrestrial ecosystem carbon cycle and carbon source and sink function. Based on the national forest investigated data from 1989 to 2008,the carbon storage of forests in Qinghai province was estimated by the linear relationship between stand biomass and volume. The results showed that (i) The forest area increased from 246.50 * 10~4 hm~2 in1989 to 355.00 * 10~4 hm~2 in 2008. (ii) The total carbon storage of forest vegetation in Qinghai increased 303.92 * 10~4 t from 814.34 * 10~4 t in 1989 to 1118.264 * 10~4 t in 2008 and by 1.68% annually during the study period,which indicated that the forests in Qinghai province played a role as a sink of atmospheric carbon dioxide, carbon sink and sequestration was strengthened with forest area increasing during the last 19 years. (iii) Carbon sink increments of main forest types ranged as Cypress > Betula > Populus > Picea,which indicated that these several kinds of forests played an important role in carbon sink function of Qinghai forest vegetation. If the current forest was managed well,it would become a huge potential carbon sink in the future.
