摘要
为合理评估再生建筑废料绿色度、提升再生建筑废料的利用率,文章提出设计再生建筑废料绿色度评价模型。首先,结合再生建筑废料的控制性与优选性指标,以及其生命周期各阶段与环境间形成的输入、输出情况,确定绿色度评价指标;然后,依据目标层、准则层、指标层及子指标层的层次结构,构建绿色度评价指标体系,通过可拓层次分析法创建可拓区间判别矩阵,确定各层评价指标权重;最后,运用模糊综合评价法逐级评价各层指标,得出再生建筑废料的总体绿色度评价得分,完成再生建筑废料绿色的评价。结果表明,该模型可实现再生建筑废料的绿色度评价,其总体绿色度评价得分最高为再生建筑废料e,而得分最低的为再生建筑废料f,且其生产阶段与应用阶段的绿色度综合评价得分较低,而这两个阶段在整体绿色度评价中具有较高影响,故未来需重点改善其这两个阶段的绿色度,以提升其总体绿色程度。
In order to reasonably evaluate the green degree of recycled construction waste and improve the utilization rate of recycled construction waste,this paper proposed to design a green degree evaluation model of recycled construction waste.Firstly,combined with the control and optimization indexes of recycled construction waste,as well as the input and output between each stage of its life cycle and the environment,the green degree evaluation index was determined;Then,according to the hierarchical structure of target layer,criterion layer,index layer and sub index layer,the green degree evaluation index system was constructed,and the extension interval discrimination matrix was created by the extension analytic hierarchy process to determine the evaluation index weight of each layer;Finally,the fuzzy comprehensive evaluation method was used to evaluate the indexes of each layer level by level,and the overall green evaluation score of recycled construction waste was obtained to complete the green evaluation of recycled construction waste.The results showed that the model could realize the green degree evaluation of recycled construction waste.The highest overall green degree evaluation score was recycled construction waste e,and the lowest score was recycled construction waste f.the comprehensive green degree evaluation score of its production stage and application stage was low,and these two stages had a high impact on the overall green degree evaluation,Therefore,in the future,it was necessary to focus on improving the green degree of these two stages in order to improve the overall green degree.
