摘　　要：为探索改善城市微气候的地下空间开发策略,以围合式城市形态下地下商业街开发为例,选择室外CO浓度为评价指标,运用微气候模拟软件ENVI-met量化研究不同地下商业街开发强度、竖井排风位置、竖井排风高度以及地面横向乔木、竖向乔木、大灌木、小灌木和草四种绿化等设计因素对室外CO浓度的影响,以此探索基于城市微气候的地下商业街设计策略。结果表明,随着地下商业街开发强度的增加,室外的CO浓度变高,污染范围变大;提高竖井排风高度,竖井排风选择分散布置,在开发区域地面种植草或者大灌木,能够降低室外CO浓度。In order to explore the development strategy of underground space to improve urban microclimate,this research takes the development of underground commercial street in the enclosed urban form as an example.It chooses the outdoor CO concentration as the evaluation index to quantitatively evaluate the effects of the development intensity of underground commercial street,the position of shaft exhaust,the height of shaft exhaust and different ground greening configurations of transverse trees,vertical trees,large shrubs,small shrubs and grasses on the outdoor CO concentration by using the microclimate simulation software ENVI-met.The results represent that soaring the development intensity will enhance the outdoor CO concentration and the range of pollute area.The research properly increases the height of shaft exhaust,chooses dispersed layout for shaft exhaust,and planting grass or large shrubs on the ground in the development area of underground commercial streets,which can effectively reduce the outdoor CO concentration.
