摘　　要：基于绿色供应链模式理论,研究木结构建材认证体系完善度、产品丰富度模型和建材流通方式的碳排放对共生效应的影响,并对双链模型共生单元进行优化设计。建立了木结构建材流通链、生态链模型,以及两者的共生关系模型。定性得到木结构建材的认证体系可确保森林的可持续经营和建材的质量;定量提出产品丰富度系数K的计算模型,以权重比确定木结构建材原料树种的可替代性;实际测算木结构建材不同流通方式的碳排放,确定一定条件下的低碳流通方式。Based on the model of forestry green supply chain, the influences of the factors on mutualism were discussed,including the completeness of certification system for wooden building materials （WBMs）, prod- uct diversification model,and carbon emission of WBMs. An optimization design was conducted for the u- nits of the mutualism model. Models for the WBM circulation chain, ecology chain, as well as mutualism be- tween circulation and ecology chains were established. A qualitative result was concluded that the certifica- tion system for WBMs could guarantee the sustainable forest development,and at the same time, promote the quality of WBMs. Moreover,this paper proposed a quantitative model for the calculation of the coeffi- cient of product diversification （K） and specified the alternatives of raw materials by a weight equation. The carbon emissions of different circulation ways of WBMs were actually measured to determine a circula- tion way with the lowest carbon footprint.
