| 【目的】探索人工林碳动态，评估造林对陆地碳源/汇的贡献。【方法】以我国南方4省(浙江、福建、江西和湖南)杉木人工林为研究对象，基于样地调查数据和文献数据，利用碳核算模型CO2FIX模拟杉木人工林生物量、土壤和木材产品的碳动态。【结果】碳核算模型CO2FIX能够较好地对我国南方4省杉木人工林的生物量碳进行模拟，模型所选用的其他参数在研究区域具有较好的代表性和适用性。经过5个轮伐期（129年），杉木人工林在生物量、土壤和林产品中的储碳量共增加23.56 t/hm2，碳储量年均增加0.23 t/hm2。【结论】我国南方4省杉木人工林地在未来103年共能吸收大气CO2 0.23 Pg，杉木人工林与其他森林生态系统一样，具有较强的碳汇功能。 |

| Abstract: |
| 【Objective】This study explored the carbon dynamics in Chinese fir plantation and evaluated the contribution of afforestation to carbon emission/sink. 【Method】Based on sample-plot survey data and literature data,the carbon dynamics of Chinese fir plantation including biomass,soil and wood products were simulated using carbon accounting model CO2FIX in four provinces in southern China (Zhejiang,Fujian,Jiangxi and Hunan).【Result】The CO2FIX model can preferably simulate the biomass carbon in Chinese fir plantation in the four provinces.Other selected parameters used in the model also had good representativeness and applicability in the study area.After five rotations in 129 years,the total carbon storage in biomass,soil and wood products would increase by 23.56 t/hm2 with an annual increasing rate of 0.23 t/hm2.【Conclusion】In the next 103 years,Chinese fir plantation would absorb a total CO2 of 0.23 Pg from atmosphere in the four provinces.Thus,Chinese fir plantation has as strong carbon sink function as other forest ecosystems. |
