我国乔木林碳储量及碳汇动态分析

Dynamic Analysis of High Forest Carbon Storage and Sequestration in China

利用我国第二次到第八次全国森林资源连续清查数据,采用生物量换算因子连续函数法估算了我国乔木林碳储量现状,实现了对乔木林碳储量总量、结构和地理分布的动态分析。在此基础上评价乔木林的碳汇功能,认为我国乔木林碳储量自20世纪70年代末以来出现了先下降后上升的变化趋势,森林资源发挥着越来越重要的碳汇功能。

This paper estimated the status of high forest carbon storage based on forest resources continuous inventory from the second time to the eighth with the method of variable biomass expansion factor function and completed the dynamic analysis of total amount,structure and geographical distribution of high forest carbon storage. Based on the above,high forest carbon sequestration in China was evaluated. It concluded that high forest carbon storage in China firstly decreased,and then increased since the late 1970 s. Forest resources were playing an increasingly important role of carbon-sink function.
