紧凑城市作为能够促进城市可持续发展的空间形态之一,在许多西方国家得到了广泛的支持,在英国,已将其作为国家规划政策中的核心要素,它在阻止耕地的进一步丧失和提高能源节约的效率方面起到了重要作用。反观我国城市发展现状,城市的无序蔓延已成为制约可持续发展的重要问题,将紧凑城市的空间发展战略适时、适当地引入,无疑是一种有效的途径。在符合我国政治、经济、文化的状况下,借鉴紧凑城市的相关理念,可加强宏观调控,防止城市过度扩张;有助于推动城市改造的进程,提高公共基础设施及社区资源的有效利用;并从减少交通量等角度发挥优势。案例以伦敦为例,着重介绍学者们对怎样使伦敦成为紧凑的、可持续发展的人性化都市所做的探讨。——主持人 As one of the spatial forms that can promote the sustainable development of the city, compact city has gained widespread support in many western countries. In the UK, it has been regarded as the core element of national planning policy. It is impeding the further loss of cultivated land and energy Saving efficiency has played an important role. In contrast, the status quo of urban development in our country and the disorderly spread of cities have become important issues that restrict the sustainable development. It is undoubtedly an effective way to introduce the spatial development strategy of compact cities into China timely and appropriately. In line with China's political, economic and cultural conditions, drawing on the concepts of compact cities can strengthen macro-control and prevent over-expansion in urban areas; help promote the process of urban renewal and improve the effective utilization of public infrastructure and community resources; and From the perspective of reducing traffic and other advantages. The case takes London as an example, highlighting how scholars have explored how London can become a compact, sustainable, and humane city. --host
