摘 要 ：自1960年代以来，由于废纸浆在全球造纸浆中比例不断提高，原有的纸张生态足迹计算方法——以原木浆纸的木材消耗量为计算基础——需要改进。通过分析纸浆结构的变化、纸浆与纸的关系、纸浆耗木量、废纸成浆率等，定量地表征了废纸回收对纸张木材消耗的影响，得出1t纸消耗的木材应为3.879  m3而略小于原来的4 m3的结论。在此基础上，重新计算纸张的生态足迹，得出1t纸的生态足迹为2.569 hm2森林。

Abstract:Since 1960s, the percentage of recover paper pulp in the global papermaking pulp was increased continuously. Therefore, the original computation method of paper ecological footprint, based on the wood consumption of pure wood pulp, need to improve. The author researched the impact of paper recycle utilization to papermaking wood consumption according to analyze pulp construction change, relationship of pulp and paper, pulp wood consumption and recover paper pulp conversion rate etc. It is concluded that 1 ton paper consume 3.879 m3 wood less than original 4 m3. Based on this, the author re-counted 1 ton paper ecological footprint is 2.569 hm2 forest. Compared with the previously research, the result is more reasonable.
