森林经营管理与碳汇潜力研究——以白河林业局为例

Study on Forest Management and Carbon Potential——A Case Study in Baihe Forest Area

文章利用加拿大森林模拟和优化模型FSOS,以中国吉林省白河林业局为案例,探讨不同的森林经营管理方案对白河林业局森林碳储存、木材生产和经济效益的影响。结果表明,每年生产相同的木材,多目标经营方案比单一目标经营方案的长期经济效益每年高出约1亿元人民币,CO2储存量增加400万t,而每年采伐干扰面积从1800 hm2减少为1000 hm2。森林的采伐经营可能在短期内是碳源,但是从长期角度看,适当采伐经营可以增加森林和林产品中的总碳储量。

This paper applies the Canadian forest simulation and optimization model FSOS （Forest Simulation and Optimization System） to explore the carbon storage capacity of Baihe forest area in the northeast of China. The re- sults show that two management scenarios produce the same timber, however the multiple-objective scenario does not only have 30% more profit but also store 1 million tons more carbon and have 800 ha less disturbed area per year than the single-objective zoning scenario. Carbon stored in the wood product makes a great contribution for forest carbon storage capacity, the no-harvest scenario stores more carbon than the harvest scenario for the most time of the planning horizon without including carbon accumulated in the wood product; however the result is different if the carbon accumulated in wood product is included. A larger sustainable carbon storage can be achieved over long term by proper harvests and utilizations.
