发展地下空间是亚洲高密度城市空间的重要组成部分,大城市的地下公共空间建设与轨道交通有着密切的联系。针对香港、台北和深圳的典型地下公共空间的案例研究发现,以地下街为代表的地下空间在连接轨道站的同时,具有丰富的功能意义。不同的建设指导思想,也会产生不同的结果。地下街一方面提供了良好的步行系统,改善了所在区域的慢行交通可达性,另一方面则为城市空间的集聚、功能的填补提供了可能。合理、适度地建设地下空间有利于提高城市空间紧凑程度,提高市民出行效率。 The development of underground space is an important part of high-density urban space in Asia. The construction of underground public space in large cities is closely linked with rail transit. Case studies of typical underground public spaces in Hong Kong, Taipei, and Shenzhen have found that underground spaces represented by underground streets are rich in functional significance while connected to orbital stations. Different construction guidelines will also produce different results. On the one hand, the underground street provides a good pedestrian system, which improves the accessibility of slow traffic in the area, and on the other hand, it provides the possibility of urban space agglomeration and the filling of functions. The rational and appropriate construction of underground space is conducive to improving the compactness of urban space and improving the travel efficiency of citizens.
