摘　　要：针对地下公共空间在岭南地区实现低碳发展的气候局限性,选取传统地下空间原型地坑院进行空间拓展与组合,并与传统岭南建筑被动式通风空间相结合,提出新岭南地下公共空间概念。以岭南现代地下公共空间典型案例天环广场为例,利用CFD软件模拟其3种不同截面下的通风序列及风热环境。实验结果表明:与地面联通的地下公共空间数量越多,项目整体的气候适应性越高;地下公共空间相互连通的效率越高,通风效率也相应越高;与下沉式广场相连的通风序列风热环境最佳。最后,将新型岭南建筑的底层架空、骑楼等形式与项目的地下公共空间结合,形成新的通风序列,为项目优化提供了一定的被动式通风策略。In view of the limitations of climate and low carbon in the development of underground public space in Lingnan area,selects the traditional prototype underground space for topology,and combines it with the passive ventilation space of traditional Lingnan buildings to put forward the concept of new Lingnan underground public space.Parc Central Square,a typical case of modern underground public space in Lingnan,as an example,CFD software was used to simulate the wind and thermal environment under three different ventilation space organization planes.The experimental results show that the more underground public space connected to the ground,the better the overall climate adaptation performance.The higher the interconnection efficiency of underground public space,the higher the ventilation efficiency.The ventilation sequence connected to the sunken plaza has the best wind and thermal environment.Finally,according to the combination of the new Lingnan building's ground floor overhead,arcade and other forms with the underground public space of the project,a certain passive ventilation strategy is provided for the optimization of the project.
