Despite a persistent call for a greater recognition of the underground in urban planning practices, cities still tend to address underground resources only when the need arises. Historically, this has proven costly for cities that have neglected the potential synergies and conflicts between, for instance, urban aquifers and underground infrastructure systems or building foundations. For urban planning to remain in a paradigm of needs to resources risks rendering conflicts between urban underground activities irreversible and possible synergies unattainable. Researchers and practitioners from multiple disciplines argue for the many benefits of underground development—alternative renewable energy and drinking water sources, additional urban space and reusable geomaterials. Visualizing resource potential is a first step in raising awareness among planners of the capacities of the underground. Existing mapping methods tend to focus only on underground space development in contexts where the needs for the underground are already urgent and do not explicitly engage with the distribution of existing land uses. As an alternative to existing methods, this paper will present a procedure for mapping underground resource potential that incorporates four resources—space, groundwater, geothermal energy and geomaterials—developed by the Deep City project at the Swiss Federal Institute of Technology in Lausanne. San Antonio, Texas, a city with a complex relationship to an underground aquifer system but current little need and support for underground space, serves to illustrate the mapping method. Two future surface light rail and bus rapid transit lines, presented in recent planning reports, are examined in light of a latent but as yet untapped multi-resource underground potential. The paper concludes with a discussion of the applicability of the method to other cities and possible opportunities for improvement. 相似文献

就现行城市规划体系框架下,城市设计与规划的层次关系、法律地位、编制及审批办法等问题,提出了城市设计与城市规划一体化、城市设计具有双重地位和属性、城市设计与城市规划层次对应的三个基本理念,由此进一步提出城市规划编制实践中的城市设计可以根据具体情况分为:将城市设计纳入规划编制体系运行;城市设计作研究性的基础工作,其成果纳入规划成果进编制和审批;城市设计作为专项规划单独运行等三种不同方式进行的规范运作思路。 相似文献

上海大都市区空间结构的重构 总被引:4,自引:0,他引:4
一直以来,上海城市规划把上海大都市区的空间结构分为两个圈层,即中心城区和郊区。本文根据上海城市体系空间结构演化的规律,提出三圈层空间结构的设想,即中心城区、通勤区和郊区,认为中心城区以现代服务业的发展为主,通勤区以工业园区和大型居住区的发展为主,而郊区以发展新城为主。 相似文献

西南山地城市交通特征与规划适应对策研究 总被引:2,自引:0,他引:2
西南山地城市具有的地形地貌复杂、生态环境敏感、城市建设用地紧张等特点,不仅给城市道路交通系统的规划建设带来了一定的复杂性和特殊性,也使西南山地城市交通活动存在着与平原城市不同的特征。应基于西南山地城市居民出行特征和道路交通系统特征分析,提出西南山地城市道路交通规划适应对策,以便更好地指导该类城市的规划设计,从多方面入手对城市交通做出系统化、科学化的统筹安排。 相似文献

城市规划对城市发展作用的历史研究——以近代青岛为例 总被引:1,自引:0,他引:1
作为中国近代一个有代表意义的城市——青岛,在城市的形成和发展过程中,城市规划起到了积极的促进作用。研究显示,合理的城市规划是城市发展的前提,城市规划在城市发展的不同阶段所起的作用是不同的,具体表现在城市空间发展方向、城市空间形态演变、城市形象、城市经济活动乃至城市社会结构等方面。近代青岛不仅用事实证明城市规划与城市发展的关系,而且对认识城市发展规律、进行城市规划决策都有借鉴价值。 相似文献

Functional or land-use mix has been seminal to urban design and planning for over 50 years. Mixed-use reduces the need for travel, increases walkability and generates street-life intensity. In this paper we review existing methods of measuring functional mix and rethink the ways in which it might be conceived, measured and mapped within a framework of assemblage thinking. We suggest a live/work/visit triangle as a promising method with a focus on the interconnections between functions rather than functions in themselves. Mapping techniques are developed to reveal the ways functional mix changes at different scales from streetscape to walkable neighbourhood. This approach is tested on detailed floor area databases from the cities of New York, Barcelona and Bogotá. Rather than reducing mix to an index, such mapping reveals each city as a mix of different mixes. These maps can be understood as urban X-rays that enable interpretation and diagnosis of urban functional mix. 相似文献

中国城市的人口密度高吗? 总被引:17,自引:3,他引:14
通过国际比较,发现城市人口密度存在着巨大的时间(昼夜)和空间变化,因为城市平均人口密度反映的是午夜至凌晨6时的人口分布,且在高度集聚的就业中心区里的居住人口相当少,所以平均城市密度只能为城市规划与城市发展提供非常有限的信息。同时,通过理论分析阐述了如何评价和衡量一个城市的密度,论述了城市密度的决定机制。 相似文献

古代地图是我们阅读和研究古代城市的窗口。本文对古代“制图六体”进行了初步探讨,提出建立城市图学研究的必要性。所谓城市图学是一种研究图与空间之间对位关系的学问.就是通过对古代地图的研读和转译,建立起一套历史城市空间分析和规划设计的方法。文章强调“制图六体”是古代图学研究的基础.而地图转译则是开展这一研究的不二法门。 相似文献

Alison Todes 《Urban Forum》2011,22(2):115-133
There is a growing acceptance in international development circles of the contribution a revitalised planning can make to
addressing key urban challenges. Current expectations that planning can play roles in managing the growth of cities in ways
that promote their sustainability, inclusiveness and liveability, contrasts with past perceptions of planning as an irrelevant
discipline obsessed with spatial ordering and control. This paper considers whether the new forms of planning can address
the challenges facing cities, with particular reference to the South African context. It does so through providing an overview
of the shift in thinking about planning, and reflecting on the new agendas for planning as well as on some of their silences.
It argues that the new approaches need to be understood in terms of contemporary urban and planning theories which are rethinking
the nature of planning and its relationship to power and institutions, and which view cities as complex, dynamic places, embodying
multiple interests and spatialities. These perspectives can help to enrich our understanding of the new approaches to planning,
and to avoid ineffectiveness or a return to the negative elements of modernist planning of the past. The paper demonstrates
the argument through focusing on some of the recent themes that have received attention in the contemporary international
agendas for planning: the cross-cutting themes of sustainability and gender; the infrastructural turn in planning; and the
ambiguities of the compact city. While these are quite particular concerns, they highlight the complexities of institutionalising
the new approaches to planning, and ways of thinking about spatial planning. 相似文献
