在参阅国内外木材产品生命周期对环境影响评价方法的基础上，针对原木运输和锯材生产2段过程，结合对锯材产品生命周期评价中的环境特点，确定全球变暖、酸化、富营养化、烟尘、固体废弃物为主要的评价指标；从运输消耗和清单分析、选取影响环境类型、归类影响环境因子、计算影响环境负荷、影响环境潜值的加权标准化5个方面，构建评价模型；将实际生产中收集到的数据，应用到评价模型中计算。结果表明：在锯材产品生产中的5种影响环境评价指标中，全球变暖、酸化对环境的影响贡献值较大，其次是固体废弃物的污染、烟尘、粉尘、富营养化。提出了指导性建议，减少锯材生产对环境造成的危害。

By reviewing the domestic and international methods of life cycle impact assessment on wood products , two stages of log transportation and sawn timber production were as the study scope in combination with the characteristics of sawn timber products in life cycle assessment.We used global warming, acidification, eutrophication, dust, and solid waste in life cy-cle assessment , and established a suitable evaluation model from five aspects including energy and material consumption during transportation and inventory analysis , selection of types of environmental impacts , classification of environmental impact factors , calculation of environmental impact load , and weighted and standardized environmental impact potential . We collected the sawn timber related data from a local sawmill and input them in the evaluation model .The global warming and acidification among five environmental evaluation indices had the most environmental impacts , followed by solid waste pollution, smoke, dust, and eutrophication .We put forward some constructive suggestions with regard to sawn timber transportation and production to reduce the potential environmental impacts.
