摘要:

基于北京市第七次(2004—2008年)、第八次(2009—2013年)和第九次(2014—2018年)森林资源连续清查数据,采用生物量转换因子连续函数法,评估2004—2018年北京市森林资源碳储量的动态变化,并运用碳税法对其碳汇经济价值进行估算。结果表明:北京市的森林碳储量在2004—2008年为7.09Tg,2009—2013年为9.43Tg,2014—2018年为15.39Tg。森林碳密度在3个清查期内依次为19.94,21.97和24.75t/hm2。其中,幼龄林占林分总碳储量的比例最高,3个清查期内依次占到52.04%,47.64%和53.42%;中龄林的占比也较高,依次达到23.05%,24.78%和21.00%。北京市森林碳汇的经济价值在2004—2008年为50.75亿元,2009—2013年为57.25亿元,2014—2018年为76.52亿元,15年间的年均碳汇经济价值增量为1.718亿元。北京市森林资源的碳储量和碳汇经济价值均呈现出增长的趋势,但中幼龄林的占比较高,森林碳密度较低,应进一步加强森林的科学抚育和管理,持续提高森林的碳汇功能和价值。

Abstract:

Based on the forest inventory data of Beijing from the seventh (2004-2008),the eighth (2009-2013) and the ninth (2014-2018),the continuous biomass expansion factor method was used to evaluate the dynamic changes of forest carbon stocks in Beijing during 2004-2018,and the carbon tax assessment method was used to estimate the economic value of the forest carbon sink in Beijing from 2004 to 2018. The results showed that: the forest carbon storage in Beijing was 7.09Tg from 2004 to 2008,9.43Tg from 2009 to 2013,and 15.39Tg from 2014 to 2018. The forest carbon density was 19.94,21.97,and 24.75t/hm2,respectively. The young forest accounted for the highest proportion of total carbon storage,accounting for 52.04%,47.64% and 53.42% in the three inventory periods respectively,while middle forest accounted for 23.05%,24.78% and 21.00% in the same period respectively. The economic value of forest biomass carbon sink in Beijing was 5.075 billion yuan between 2004 to 2008,5.725 billion yuan between 2009 to 2013,and 7.652 billion yuan between 2014 to 2018,the annual increment of economic value of forest biomass carbon sink in 15 years was 171.8 million yuan. The carbon stocks and carbon stock economic value of the forest resources in Beijing showed an increasing trend,but the proportion of young forest and middle forest was relatively high,and the carbon density of forests was low,so the scientific cultivation and management of the forest should be strengthened in order to continuously improve the function and value of the forest carbon sink.

Key words: forest carbon stocks, carbon density, carbon sink economic value, Beijing
