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。木质林产品碳储量变化又是国家温室气体清单报告的一部分。为合理估算木质林产品碳储量,达喀尔会议上确立了3种估算方法框架,即:储量变化法、生产法和大气流动法。在3种方法的框架下,利用寿命分析法和逐步递归法计算我国木质林产品的碳储量。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1961-2000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一直在增长;②3种方法估算木质林产品的碳储量年平均增长量分别是11.72,8.58和7.53 Tg.a-1;③1990-2000年,木质林产品碳储量的年平均增长量分别为10.27,4.75和2.16 Tg.a-1,其中,1990年木质林产品库的碳储量分别是364.0,299.0和285.1 Tg;④从计量的角度和估算的难易程度来看,储量变化法的计量对我国较为有利。
Harvested wood products (HWP) are an important component of the carbon (C) cycle between the forest ecosystem and the atmosphere. Carbon stocks of HWP are also a part of the greenhouse gas (GHG) inventory. This research used the lifetime analysis method and step regression method based on the stock-change approach (SCA), production approach (PA), and atmospheric-flow approach (AFA), which were established in the HWP Conference in Dakar, 1998. Results showed that 1 ) HWP was a carbon reservoir in China. In addition, 2) from 1961 -2000 the carbon stock estimations of HWP increased, but differed according to the approach used with SCA, 11.72 Tg·a^-1; PA, 8.58 Tg·a^-1; and AFA, 7.53 Tg·a^-1. Also, 3) between 1990 and 2000, the average carbon stockchange increases in HWP were: 10.27 Tg·a^-1 with SCA, 4.75 Tg·a^-1 with PA, and 2.16 Tg·a^-1 with AFA; whereas the carbon stock in 1990 was 364.0 Tg for SCA, 299.0 Tg for PA, and 285.1 Tg for AFA. Thus, from the accounting perspective, China should favor the stock-change approach. [ Ch, 3 fig. 1 tab. 30 ref. ]
