为了鼓励生产者和消费者的环境责任,在森林管理过程中评估林产品的环境影响十分重要.生态足迹(EF)是一个评估产品自然资本消耗与环境影响的国际认可指标.木地板为一种三级林产品,本文通过转换的方法分别建立了三种木地板生态足迹核算模型,同时基于产量数据评估了2000–2018年三种类型木地板的生态足迹大小.文章所需数据通过对典型的木地板企业调研以及查询相关文献获得.研究结果表明:实木地板、实木复合地板以及强化木地板2000–2018年的平均生态足迹分别为3.13×106、1.05×107和5.07×106 gha,累计总生态足迹分别为5.95×107、1.99×108和9.64×107 gha.三种类型木地板不同年份间生态足迹的变异系数分别为0.45、0.87和0.76.实木复合地板的平均生态足迹和总生态足迹均为最大.同时,实木复合地板的人均生态足迹和单位生态足迹也均为最大.2000–2018年,三种类型木地板生态足迹大小均呈现不规则的增加趋势.为了降低木地板行业总的生态足迹,可以考虑降低实木复合地板的生态足迹或者使用环境友好型的实木地板.“,”To encourage the environmental responsibility of consumers and manufacturers for forest management, it is necessary to evaluate the environmental influences of forest products. Ecological footprint (EF) is an interna-tionally recognized indicator for estimating the natural capital consumption and environmental influences of various forest products. In this study, we developed an accounting model for the EF evaluation of wood flooring, which is a tertiary forest product, by the method of transformation. Next, we used that model to evaluate the EF of three types of wood flooring in China according to their production data from 2000 to 2018. We collected the necessary data by visiting typical enterprises in China and referring to the relevant literature. According to our results, the average EFs of solid wood flooring, engineered solid wood flooring and laminate flooring between 2000 to 2018 were 3.13×106, 1.05×107 and 5.07×106 gha, respectively. The total EFs of solid wood flooring, engineered solid wood flooring and laminate flooring from 2000 to 2018 were 5.95×107, 1.99×108 and 9.64×107 gha, respectively. The coefficients of variation (CV) of the EFs for these three types of wood flooring were 0.45, 0.87 and 0.76, respectively. The average and total EFs of the engineered solid wood flooring were the largest among the three types of wood flooring. The per capita EF and unit EF for the engineered solid wood flooring were also the highest among the three types of wood flooring. The EFs showed an upward trend with irregular fluctuations from 2000 to 2018 for all three types of wood flooring. It is necessary to reduce the EF of the engineered solid wood flooring and use more environmentally friendly products, such as solid wood flooring, for environmental protection.
