气候变化关联议题下木质林产品碳储量的核算与影响因素

Accounting Methods and Influences of Carbon Stock in Harvested Wood Products in the Context of Climate Changes

木质林产品的碳储量核算是当前气候变化的重要议题,木质林产品的固碳功能能够减少大气的二氧化碳排放。该文结合气候变化下的木质林产品碳储量谈判议题,综述了国内外学者对该问题的研究。基于《联合国气候变化框架公约》对木质林产品碳储量及国家排放清单的要求,结合木质林产品的分类,比较了木质林产品碳储量的核算方法以及计算模型,并对造成核算误差的影响因素进行了分析。木质林产品碳储量的核算结果主要受到核算方法选择、变量差异、消耗快慢和重复计量等4个因素的影响。

Currently, climate change is one of the most serious environmental problems, more and more countries join the team of carbon reduction and carbon storage, which is beneficial to mitigating the worsening global climate change by increasing carbon storage of harvested wood products （HWP）. This paper introduced the development of the carbon storage in HWP in the context of climate changes, summarized the studies of domestic and foreign scholars on this topic. Besides, based on the discussion of the United Nations Framework Convention on Climate Change （UNFCCC）, it compared the accounting models of carbon storage on Intergovernmental Panel on Climate Change （IPCC）, and analyzed the factors causing errors. The result shows that the carbon stock in HWP is influenced by the factors of accounting methods, difference in variables, the consumption speed and repeated measurement. It is expected that this study will have positive influence on allevia- ting the climate proh｜em and beneficial for China to get a good situation on climate change negotiations.
