森林生态系统具有重要的碳汇作用。目前，碳汇价格可以通过碳交易、碳税和固碳项目实际成本3种机制实现。本研究从森林植被碳汇功能发挥的过程出发，认为森林植被碳汇价值包括碳固定价值和碳蓄积价值两部分。在此基础上以樟子松（Pinus sylvestris var.mongolica）为例，采用固碳项目实际成本，模拟了森林植被在100年的生命历程中碳汇价值的动态变化过程。研究表明，单株樟子松碳固定的物理量和价值量动态过程曲线都呈倒“U”型；碳蓄积的物理量和价值量动态过程曲线都近似呈“S”型。在碳固定和碳蓄积价值叠加下，碳汇价值流量过程曲线近似呈“S”型，且逐渐趋近碳蓄积价值流量曲线。100年内，樟子松的碳汇总价值（资产价值）随着林龄逐渐增大，其中碳蓄积价值所占的比重逐渐增加。樟子松林分碳汇价值曲线与单株树木的曲线不完全相同，但是基本形态一致。

Based on the functional process of carbon sequestration of forest, we categorize carbon sequestration in two parts: carbon capture and carbon storage. Here,Pinus sylvestris var.mongolica was used to simulate the dynamic changing process of carbon sequestration of forest in a century using tree growth formula and the cost of carbon capture and sequestration. We found that the total carbon captured and stored by 100-year-oldP. sylvestris var.mongolica are both 966 kg C tree-1. On the assumption that the current year is the planting year, the present total carbon sequestration value (capital value) of 100-year-oldP. sylvesrtis var.mongolica is 54.78 USD tree-1 at the discount rate of 3%, with the present total carbon capture value of 18.92 USD tree-1 and carbon storage value of 35.86 USD tree-1. The dynamic process of the annual value of carbon capture is ilustrated by an upside-down U shape curve, while that of carbon storage service folows an S shape curve. The combination of the dynamic processes of carbon capture value and carbon storage value represent the changing process of carbon sequestration value, which appears to be an S shape curve.
