城市空间易行性是建设老年人友好城市必须考虑的环境指标。易行空间促进步行和体能活动,对老年人的身心健康有益。本文选取居住区密度、道路联通性和用地混合性三个指标测度香港城市空间的易行性,发现城市中心区(港岛和九龙)的空间易行性明显高于新界。相关性分析指出易行性与人口密度和第三产业就业率存在正相关,与家庭收入和地块面积存在负相关。通过专家访谈,本文分析了不同空间易行性背后的规划思路。早期城市规划推崇的小地块发展模式使中心区地块面积细碎、街道狭小,促进了居住密度和用地混合度,这是造成易行性高的主要原因。然而,这同时造成了环境污染和公共卫生隐患,对老年人身心健康不利。文章指出,未来城市规划要在地块划分的面积与多样性之间求得平衡。定量测度需结合其他研究方法探讨完善步行空间、提高宜居性与老年人幸福感的对策。  相似文献

Problem, research strategy, and findings: Planners increasingly involve stakeholders in co-producing vital planning information by crowdsourcing data using online map-based commenting platforms. Few studies, however, investigate the role and impact of such online platforms on planning outcomes. We evaluate the impact of participant input via a public participation geographic information system (PPGIS), a platform to suggest the placement of new bike share stations in New York City (NY) and Chicago (IL). We conducted 2 analyses to evaluate how close planners built new bike share stations to those suggested on PPGIS platforms. According to our proximity analysis, only a small percentage of built stations were within 100 feet (30?m) of suggested stations, but our geospatial analysis showed a substantial clustering of suggested and built stations in both cities that was not likely due to random distribution. We found that the PPGIS platforms have great promise for creating genuine co-production of planning knowledge and insights and that system planners did take account of the suggestions offered online. We did not, however, interview planners in either system, and both cities may be atypical, as is bike share planning; moreover, multiple factors influence where bike stations can be located, so not all suggested stations could be built.

Takeaway for practice: Planners can use PPGIS and similar platforms to help stakeholders learn by doing and to increase their own local knowledge to improve planning outcomes. Planners should work to develop better online participatory systems and to allow stakeholders to provide more and better data, continuing to evaluate PPGIS efforts to improve the transparency and legitimacy of online public involvement processes.  相似文献

山水城市是人工环境与自然环境协调发展的城市,是人类城市发展的高级阶段.城市门户既是城市的主要对外交通通道之一,又是城市的窗口地段,同时也是城市形象的重要载体.结合江西省永新县城仰山地区的规划设计实践对山水城市门户的设计方法进行了探讨,研究认为:山水城市门户设计必须注重保护自然山水格局,将人工建筑与山水环境相呼应,并融入当地历史文化信息,体现城市的特色与内涵;同时还应满足城市流通中多样化的功能要求,并借助山、水自然元素的引导,营造层次丰富、动态多样的城市节点空间.  相似文献

The European Landscape Convention recognises the importance of public participation for landscape planning in order to capture local knowledge, sensitive issues and conflicts, boost exchanges of information and democratise the process. However, traditional public participation methods are frequently restricted to public exposure at the final stage of the planning process. New public participation movements call for a greater role for the people at all stages. The growing development of ICT and geospatial information technologies provides new means of improving the participation process. This paper describes the public participation procedure and the participation geographic information system used to develop the Landscape Inventory of Galicia, whose results were used for the characterisation of landscape types, the delimitation of special interest areas from the locations identified by citizens and the definition of special attention areas from the degraded areas located by population.  相似文献

国外城市更新的历程与特点及其几点启示   总被引:1,自引:0,他引:1  
目前我国正处于一个工业化进程加速,经济结构发生明显变化,社会各方面都在变革的关键时期,城市更新在这一宏观背景下既面临过去大量存在的物质性老化问题,而且更交织着功能性衰退,以及与之相关的传统人文环境和历史文化环境的继承和保护的问题。因此,城市更新工作应面向更长远全局性的目标,吸取国外先进经验以及失败教训,以达到提高城市功能,调整城市结构、改善城市环境、更新物质设施、促进城市文明的目的。  相似文献

Water and land management decisions require consideration of multiple factors. Multicriteria decision analysis (MCDA) provides a structured, auditable and transparent tool that helps inform and add rigour to multioption decisions. MCDA was used in a payment for ecosystem services (PES) project to evaluate options for delivering good ecological status in Tortworth Brook, Gloucestershire, UK. Following a process of stakeholder engagement, final options considered were: (1) doing nothing; (2) modifying existing sewage treatment works; (3) a single integrated constructed wetland (ICW) targeting multiple ecosystem service outcomes; and (4) catchment wide multiple ICWs. The analysis concluded that the ‘do nothing’ option and modifying the existing works are both likely to provide poor utility and value for money. Both ICW options offered the greatest utility in terms of optimising the benefits to all stakeholders.  相似文献

绿视率为城市公园环境评估的重要指标,其对人体身心健康影响的效应有待深入探讨,研究结果可为城市绿地规划建设及优化提供参考。基于城市公园实景影像,通过VR技术、利用POMS量表与语义分析量表评分作为心理评估指标,皮电信号值作为生理评估指标,探究基于绿视率的城市公园环境对人体身心健康的影响机制。结果表明:(1)城市公园绿色空间静态VR体验能使个体精神放松,增加积极情绪,减少消极情绪;(2)在实验条件下(绿视率范围10%~66%),随着场景绿视率的增加,个体心理、生理恢复愈加显著;(3)当环境绿视率低于35%时,其对个体的身心恢复受多因素协同影响,如水体面积、空间开敞度、硬质场地面积等;当绿视率值高于35%时,绿视率为环境对个体身心影响的主导因子。  相似文献

场所依恋理论作为当代人-地情感联结研究的核心,是增强人与场所情感联系、提升居民归属感和身份认同感的重要切入点。然而场所依恋传统测量方法因情感数据与空间数据的脱节,较难探讨场所依恋强度的空间分异特点,其测量结果也难以直接指导实际的规划与管理。为此,在总结形成基于PPGIS的场所依恋综合测量方法框架的基础上,以长春水文化生态园为例开展场所依恋的多维度综合测量和可视化制图,并基于语义分析解析同类型空间场所依恋强度差异的原因。以期从情感数据、场所意义和空间数据相结合的角度为场所依恋理论在风景园林领域的应用提供方法支撑。  相似文献

Four underground resources have been seen as having a long-term potential to support sustainable urban development: underground space, groundwater, geomaterials and geothermal energy. Utilization of these resources proposes a new paradigm of economic development: underground urbanism. The new management approach named “Deep City Method” is put forward to aid decision-makers to integrate global potential of the urban underground into city-scale strategic planning. The research output will be presented in form of two papers each with a different focus. Part 1 aims to introduce the concept, process and initial application in Switzerland; Part 2 is devoted to show methodological insight for a new zoning policy in China and investment scenarios for project cost viability.This Part 1 paper will begin by presenting the fundamental concept of the Deep City Method, followed by a proposition for a trans-institutional planning process. The application is firstly based on a rating system to identify cities having a potential for underground development. The city of Geneva is selected for conceptual application and strategic level study. Further operational steps are required in order to generalize the concept to other cities around the world.  相似文献
