文章运用储量变化法对1961~2012年中美木质林产品的碳储量进行了核算和分析,结果显示,1961~2012年美国木质林产品碳储量总量高于中国,但中国增长速度高于美国,2002年起中国木质林产品年增长碳储量显著增加,并于2007年超越美国,分析发现,美国木质林产品的碳储量主要受经济危机的影响上下波动,中国木质林产品的碳储量主要受中国自身经济政策的影响而变化。通过对中美木质林产品的减排贡献进行核算,发现中国木质林产品的碳清除贡献均值为1.23%,大于美国的碳清除贡献均值0.92%,继而对中美应对气候变化的减排政策和措施进行比较,期望对中国调整减排策略提供参考。
The paper calculated and analyzed the carbon stocks of Sino-US wood-based forest products from 1961 to 2012 using the change of reserves method. The results show that the total carbon stocks of the United States in 1961 to 2012 were higher than that of China, but the growth rate of China was higher than that of the United States . Since 2002, the annual growth of carbon stocks in China’s wood-based forest products has significantly increased and surpassed that of the United States in 2007. According to the analysis, the carbon stocks of wood-based forest products in the United States fluctuated mainly from the impact of the economic crisis. The carbon stocks of China’s wood-based forest products were mainly affected by China Its own economic policy changes. By accounting for the contribution of China-US wood-based forest products, the average carbon emission contribution of China’s wood-based forest products is 1.23%, which is greater than the average of 0.92% of the carbon emission contribution from the United States. Measures to compare and expect to provide reference for China to adjust emission reduction strategies.
