中国工程院院士钱七虎最近提出,我国应把地下空间的开发利用放到可持续发展的战略高度超前考虑,并有所准备。他说,许多科学家已经预见到,要减少耕地被侵占,改善城市严重恶化的环境,一条有效途径是把一些城市的交通设施及公用设施,商业、体育、文娱场馆等转移到地下去。旧金山、巴黎把交通枢纽建在地下,芬兰、瑞典的音乐厅建在地下,美国明尼苏达 Qian Qihu, an academician of the Chinese Academy of Engineering, recently proposed that China should consider the development and utilization of underground space ahead of the strategy for sustainable development and be prepared. He said that many scientists have foreseen to reduce the use of cultivated land to invade and improve the severely deteriorating environment of the city. An effective way is to transfer some of the city’s transportation facilities and public facilities, commercial, sports, cultural and entertainment venues to the ground. San Francisco and Paris have built transportation hubs underground, Finnish and Swedish concert halls are underground, Minnesota, USA
