摘　　要：用国际上森林碳汇项目中普遍采用的碳计算方法,对大青山不同初始密度下的马尾松林碳汇经济价值变化过程进行研究,提出了碳汇经济成熟的定义,并分析了初始密度对碳汇经济成熟的影响,最后就碳汇经济成熟对于开展森林碳汇的作用进行了探讨。结论:不同初始密度,达到碳汇经济成熟时的年龄和年平均碳汇经济价值净现值均不同,初始密度越高,碳汇经济成熟越早,达到成熟龄时的年平均碳汇经济价值净现值也越高。The article adopts the carbon measurement methods commonly used in the international projects of forest carbon sink, analyzes the change process of Pinus massoniana forest carbon storage under different site conditions in Daqingshan, and gets the definition of the carbon storage maturity of maximum forest income. Then it also analyzes the impact of different site conditions on the carbon storage maturity of maximum forest income, finally, discusses the effect of carbon storage maturity of maximum forest income on exploring the project of forest carbon sink. The conclusion is that： with different initial densities, the age reaching carbon storage maturity of maximum forest income and the annual mean of net present worth are different, showing that the higher the initial density is, the earlier the carbon storage maturity of maximum forest income occurs, and the higher the annual mean of net present worth reaches at the age of maturity.
