The Community Infrastructure Levy: An Information Economics Approach to Understanding Infrastructure Provision under England's Reformed Spatial Planning System

This review paper introduces a research agenda designed to invigorate interest in information economics as a conceptual framework within which to analyse the purported transition from regulatory land-use planning, such as that operating in England prior to 2004, to “spatial planning”. In considering one specific area of reform—the management of infrastructure provision—a research agenda is introduced to investigate a specific policy instrument, the Community Infrastructure Levy. It is approached as a transaction cost, the determination of which is a function of how information is traded between counterparties. In conceptualizing important information asymmetries between local planning authorities and the development industry a case is made for further empirical research.     

基于社区发展的城中村改造规划策略研究——以钦州市上沙村为例

反思我国现阶段城中村改造产生利益问题的规划原因,提出"社区发展"是规划转型方向的理论观点,即城中村改造规划应从规划内容、过程和保障等三个方面融入"社区发展"。在此基础上,借鉴相关研究成果,尝试提出构建基于社区发展的城中村改造规划策略。以钦州市上沙村改造规划为例,探索一种从单纯物质更新转向社区发展的改造模式,以期实现城中村的全面发展。     

Responding to Change: Foundations for an Integrated Regional Approach to Community Safety and Social Cohesion

Issues relating to crime and community safety attract much media and political attention in Australia. However, responses are usually seen to be reactive and punitive. Integrative and proactive collaborative initiatives, involving community members as key stakeholders, have the potential to facilitate more effective and efficient outcomes. This study, undertaken in collaboration with a regional community safety network, was prompted through community safety concerns associated with predicted population growth in the region, and the complex and interrelated nature of many safety issues. Research results suggest three key areas will need to be addressed.     

让自然参与设计：一种基于自然演替的 城市自生群落改良设计途径

城市自生群落具有重要的生态服务功能与潜力,但因其外貌不被公众所接受而难以在城市公共空间中应用。将群落生态学和设计学相结合,探索一种介入栽培植物对城市自生群落进行改良,最终形成具有一定美学价值的植物群落的途径。实验以植物群落设计美学原理和种间竞争原理为依据,向已经演替1年的城市自生群落中引入63种栽培植物,按照分层的方式对群落进行改良。3年的观测结果表明,有61.9%的栽培植物可以在城市自生群落中定居并建立优势,能对76.7%的自生植物起到抑制作用,使55.8%的自生植物消失。相比城市自生群落,改良后的群落美观度提高29.4%,公众接受度提高24%,群落的物种丰富度提高至2.29倍。相比一般的人工植物群落,改良后的群落可以节约58.2%的建植成本,降低83.9%的浇水成本和67.8%的除草成本。实验证明改良设计是一种可行的群落设计途径,能有效提高群落的物种丰富度和美学价值,同时让自然参与群落设计过程,实现人与自然的合作。     

行政服务中心的“城市性”——黄梅县行政服务中心规划与设计探索

在当前我国行政服务中心新建和改扩建项目的数量逐渐增多、功能走向多元的背景下,如何发挥行政服务中心在城市总体布局、地域文化、经济发展、建筑形象上的"城市性"作用成为热点问题。该文通过介绍黄梅县行政服务中心项目的规划与设计,阐述了对于行政服务中心"城市性"作用的理论与实践探索。即在设计中基于原城市设计的基础和地域文化,并延续其空间序列、结构脉络;同时以生态绿色的建筑观来回应被重塑的基地环境。最终达到开放性、文化性和亲民性的设计目标。     

注重综合性思考突出新农村特色--北京延庆县八达岭镇新农村社区规划

就如何进行新农村社区的规划设计,笔者在实践中进行了总结,提出了应以农民为核心,以农民利益为出发点,以促进农村发展为目标,始终贯彻农民是使用者、受益者的思想;指出新农村社区规划应从农村经济产业、土地集约、社会结构、生产活动与生态、人文环境等多方面进行综合思考,并在空间规划中逐项落实的设计思路,介绍了在北京延庆八达岭镇的新村规划中所做的努力.
