摘　　要：为使城市道路植物配置最大限度地发挥绿色植物的生态功能,进一步推动我国“双碳”政策的实施,选取西安市长安区西部大道东段道路作为研究范围,通过对实测场地内的植物群落调研,讨论配置现状与CO_(2)浓度间的关系;利用ENVI-met在实测分析的基础上,定量地从郁闭度、树龄和群落类型3个方面,给出针对西安市城市道路碳收支平衡下的植物配置具体优化策略。结果表明,道路绿带能对CO_(2)发挥一定的削减和封存作用;同等配置条件下的道路绿带中,绿带宽度越大、绿量越高的绿色空间的固碳作用也越高;通过线性拟合得出郁闭度、树龄和群落类型中,群落类型对CO_(2)浓度的影响程度最大。In order to optimize the ecological functions of green plants for future urban road plant allocation,it is essential to further advance the implementation of Chinas"double carbon"(carbon peaking and carbon neutrality)policy.This study focused on the east section of West Avenue in Changan District,Xian City,to examine the relationship between current plant arrangement and CO_(2) concentration in order to provide a basis for quantitative optimization strategies using ENVI-met.The results indicated that wider green belts and higher vegetation density contributed to greater carbon sequestration effects,with community type having the most significant impact on CO_(2) concentration compared to canopy density and tree age.
