高速铁路做为高效的长途交通运输方式,为城市发展带来了促进作用,因而受到世界各国的广泛关注。很多城市从高速铁路的到来中看到了与其相关的城市更新及公共空间改造机遇,使其更好地融入城市整体结构。巴塞罗那利用新建高速铁路所提供的城市更新机会,以铁路设施做为公共空间载体,采用更新城市功能和改善公共空间相结合的手段,实现了高密度城市空间发展的新途径。 As an efficient long-distance mode of transport, high-speed railways have played a catalytic role in urban development and are therefore attracting the attention of all countries in the world. Many cities saw the opportunities associated with urban renewal and public space renovation from high-speed rail to better integrate themselves into the overall city structure. Taking advantage of the urban renewal opportunities provided by the new high-speed railway, Barcelona uses the railway facilities as a carrier of public space and adopts a combination of urban renewal and public space improvement to realize a new approach to the development of high-density urban space.
