一、拓展空间、节约用地 在地少人多的中国开发中心区地下空间不仅可取得巨大的社会和环境效益,而且具有重大的战略意义。 地下空间的开发包括建筑地下室空间和独立式地下空间两大类,建筑地下室空间的开发与建筑师的关系更为密切,意义更大。日本尽管以地下街闻名于世,其实只占公有地下空间面积的5.3％,而地下室空间则占76.9％,说明地下室空间是地下空间的主体。我国 First, expand space and save land The underground space in China’s central development center with a large number of people is not only able to achieve great social and environmental benefits, but also has a major strategic significance. The development of underground space includes two categories of building basement space and independent underground space. The development of building basement space is more closely related to architects and has greater significance. Although Japan is famous for its underground streets, it actually accounts for only 5.3% of the public underground space, while the basement space accounts for 76.9%, indicating that the basement space is the main body of underground space.
