摘要：伐后木质林产品作为森林生态系统碳循环的一个组成部分,对森林生态系统和大气之间的碳平衡起着至关重要的作用。为准确合理估算木质林产品碳储量和我国参加气候变化谈判提供依据,在达喀尔会议上确立的3种估算方法框架下,即：储量变化法、生产法和大气流动法,利用寿命分析法和逐步递归法以及国内参数计算我国木质林产品的碳储量,且对生产法的应用提出了一种新假设思路,并分析我国木质林产品在替代建筑材料方面的减排潜力,结果显示：①分别利用储量变化法、生产法和大气流动法估算我国1961-2004年木质林产品的碳储量变化,证明我国的木质林产品是一个碳库,并且这个碳库的碳储量不断在增长;②3种方法估算1961-2004年木质林产品碳储量的年平均增长量分别是11.73M.ta^-1（Mt=10^6t）、9.31Mt.a^-1和7.90Mt.a^-1;③木质林产品在建筑材料领域的替代作用以及延长其使用寿命使其减排潜力增大;④从碳储量计量和估算的难易程度来看,储量变化法的应用可能对我国较为有利;⑤针对生产法假设的实践应用,还需要进一步的研究。
Harvested wood products（HWP）,as one of the components of carbon cycle of forest ecosystem,plays an important role in the carbon balance between forest ecosystem and atmosphere.The carbon stock of HWP is also a part of greenhouse gases（GHG） inventory.Carbon stock of HWP in China was estimated by lifetime analysis method and step regression method based on Stockchange approach,Production approach and Atmospheric-flow approach which were established during Dakar Session in 1998 and a new hypothesis on application of Production approach was proposed.The results showed that the HWP was a carbon reservoir in China,and the carbon stock of HWP was increasing during 19612004.For the period of 19612004,the estimations were different by Stock-change approach,Production approach and Atmospheric-flow approach,the average increased amount of carbon stock-change in HWP were 11.73Mt·a^-1,9.31Mt·a^-1,and 7.90Mt·a^-1,respectively.The potential of emission reductions of HWP would increase through its substituting function in architecture area and its used life prolonging.Stock-change approach would be favorable to China based on the actual situations for estimate the carbon stock of HWP.Because of the difficulty and complexity in practice,further research should be done for the application of production approach.
