中国原木进口对洲际森林生态足迹的影响

The Impact of Chinese Log imports on Intercontinental Forest Ecological Footprint

运用生态足迹模型测度了1995～2007年中国原木进口引起的森林生态足迹转移,特别关注了中国原木进口的森林生态足迹与全球森林生态足迹和承载力的比较。结果表明：虽然从欧洲原木进口的森林生态足迹输入有明显增长,但中国原木需求更多依赖本国供给,对亚洲、大洋洲及非洲等区域影响较小,并没有证据表明中国原木进口严重威胁到世界森林资源。

The demand for timber in China and the gap in supply hm2s resulted in increased import of logs year by year. This has raised concerns that China may represent a threat to world forest resources. In this study, an ecological footprint model is used to measure the forest impact embodied by Chinese log imports from 1995 to 2007. Special attention is given to the trend in the ratio between China＇s forest ecological footprint with respect to imported logs and the biocapacity of the origin of the imports. Chinese log import hm2s increased the forest ecological footprint from Europe, while those from Oceania and Asia, and Africa were less affected. Chinese log demand continues to rely more on domestic supplies. We find little evidence thm2t Chinese log imports present any serious threat to world forest resources.
