基于森林资源二类调查数据，估算了2009年北京市森林植被的固碳量。根据各亚带生物量估算出的净生物量（ΔB），结合Δ B与各亚带生物量之间的函数关系，计算了亚带水平森林植被的固碳量。林地的生物量采用生物量扩展因子（BEFs）法计算，灌木地和其他林地的生物量采用参照灌木的生物量、盖度和高度以及各亚区的灌木盖度和高度进行估算。经济林地作为一种特殊的林地类型，其生物量是以单株生物量和株数来计算的。研究了森林植被固碳量随海拔高度、树种和林分年龄的变化规律。结果表明，北京森林植被固碳量为4.12 × 106 tC/yr，平均固碳率为3.94 tC/（ha·yr）。海拔60 m以下的平原区和海拔400 ~ 800 m的低山区森林的固碳量占森林植被固碳总量的56.91%。森林植被的固碳率在海拔< 60 m的平原区最高，而在低平原向低山区过渡的200 ~ 400 m的区域，由于人为干扰强烈，固碳率显著下降。杨树的固碳作用。森林和栎属森林植被的相对含量高于其他植物种，占总含量的25.33%。< 40年生的森林固碳量占总固碳量的45.38%。森林植被的固碳率在30-40年的林龄时达到高峰。因此，保护北京森林，限制平原向低山区过渡区的人为干扰，培育新建立的疏林，是提高森林植被固碳能力的关键。
Based on forest inventory data (FID) at sublot level, we estimated the carbon sequestration in forest vegetation of Beijing, China in 2009. In this study, the carbon sequestration in forest vegetation at sublot level was calculated based on net biomass production (ΔB) which was estimated with biomass of each sublot and function relationships betweenΔBand biomass. The biomass of forested land was calculated with biomass expansion factors (BEFs) method, while those of shrub land and other forest land types were estimated with biomass, coverage and height of referred shrubs and shrub coverage and height of each sublot. As one of special forested land types, the biomass of economic tree land was calculated with biomass per tree and tree number. The variation of carbon sequestration in forest vegetation with altitude, species and stand age was also investigated in this study. The results indicate that the carbon sequestration in forest vegetation in Beijing is 4.12 × 106tC/yr, with the average rate of 3.94 tC/(ha·yr). About 56.91% of the total carbon sequestration in forest vegetation is supported by the forest in the plain with an altitude of < 60 m and the low mountainous areas with an altitude from 400 m to 800 m. The carbon sequestration rate in forest vegetation is the highest in the plain area with an altitude of < 60 m and decreased significantly in the transitional area from the low plain to the low mountainous area with an altitude ranging from 200 m to 400 m due to intensive human disturbance. The carbon sequestration ofPopulusspp. forest andQuercusspp. forest are relatively higher than those of other plant species, accounting for 25.33% of the total. The carbon sequestration in vegetation by the forest of < 40 years amounts to 45.38% of the total. The carbon sequestration rate in forest vegetation peaks at the stand age of 30–40 years. Therefore, it would be crucial for enhancing the capability of carbon sequestration in forest vegetation to protect the forest in Beijing, to limit human disturbance in the transitional area from the plain to the low mountain area, and to foster the newly established open forest.
