摘　　要：为优化地下空间覆土深度改善室外微气候,提出地下空间覆土深度对地面植物群落及室外微气候的影响机理和覆土深度优化流程,运用ENVI-met对围合式住宅区在不同乔灌木比例下(2:3,1:2和1:3)由中高层和中低层植物搭配形成的植物群落下的室外微气候进行模拟,并根据设计者的需求优化地下空间覆土深度。结果表明:如果想要改善室外热舒适度,应采用中低层植物搭配,1/4、2/4和1/4面积的地下空间开发区域覆土深度应分别设置在800~900 mm、450~600 mm和300~400 mm。To optimize the design of the OTUS(overburden thickness of underground space)for improving the outdoor microclimate,this study summarized the influence mechanism of the OTUS on plant community and outdoor microlimate,and proposed a flow chart of the optimization design of underground space overburden thickness.A typical enclosed layout residential area in Nanjing was taken as the research object on which to perform a numerical study of the influence of plant communities formed by two types of plant collocations(a middle-and low-level plant collocation and a middle-and high-level plant collocation)on the outdoor microclimate under three different ratios of trees to shrubs(2:3,1:2 and 1:3),and to provide suggestions regarding the design of the OTUS according to designer s requirements.The conclusions were summarized that if designer wants to improve outdoor thermal comfort,the OTUS should be designed to satisfy the requirements for middle-and low-level plant collocations and the overburden thickness of 1/4,2/4 and 1/4 underground space development area should be set to 800~900 mm,450~600 mm and 300~400 mm respectively.
