频繁市政工程建设背景下的地下管线GIS数据更新方法

城市地下管线GIS数据库建成后,即面临数据应用-更新-维护-应用的反复循环的问题,特别是在城市快速建设与发展时期尤其如此,本文就昆明市滇池治理重点工程-城市地下雨污分流改造为代表,针对过程中对地下排水管线GIS数据的使用,尤其针对数据需求、数据采集、数据更新过程及地下管线GIS数据库工作方式设计与运行,提出大工程背景下解决地下管线信息更新存在问题的若干技术方法。     

城市轨道交通枢纽的地下空间综合体评价方法

在建立城市轨道交通枢纽地区地下空间综合体评价指标体系的基础上,用层次分析法求出了各评判指标的权重。并以上海某轨道交通枢纽地区地下综合体为例,采用基于层次分析法的线性加权和法对城市轨道交通枢纽地区地下空间综合体的规划开发进行评价。     

国外城市规划中公众参与的经验及启示

分析提炼了国外城市规划公众参与的经验:公众参与具有法律保障;城市规划相关信息透明公开;制订了详细的公众参与程序;公众参与方式多样,并因规划阶段而异;社区组织和居民团体在公众参与中发挥了主体作用;提高公众参与能力。在分析的基础上,结合我国的具体国情,提出了促进我国城市规划中公众参与进一步发展的几点启示。     

城中村认识与城市发展

城中村是我国城市化建设中的特有现象,其自身的发展对于城市化的进程有着重要的影响。本文从城中村的起源,特点进行分析,结合城市自身的发展要求,从城市整体规划层面提出治理建议。     

The management of urban surface water drainage in England and Wales

Partly in response to the UK flooding events of 2007, a number of reports have recently been produced addressing the legislative, administrative, institutional and structural practices that are required to improve urban surface water management and hence reduce future flooding incidents and associated pollution impacts. This paper addresses the principal barriers to progress that have been identified and how these are likely to be overcome. Improved and integrated organisational structures, process and procedures are required and relationships between flood risk management and water quality need to be addressed at regional, area and local levels as well as legislative clarification on surface water discharges. Nontechnical aspects will need to be supported by new modelling approaches for flood risk prediction at both local and catchment scale with effective communication systems and tools being developed and implemented for full and effective stakeholder participation.     

An integrated VR–GIS navigation platform for city/region simulation

This paper introduces a virtual city oriented VR–GIS platform which synthesizes several latest information technologies including virtual reality, 3D geographical information system, remote sensing, and multi‐dimensional visualization. The platform is a seamless integration of VR functions and GIS analysis methods, which can be used to organize and present massive spatial data. It also supplies 3D spatial analysis functions, 3D visualization for spatial process and natural simulation, and serves as an engine platform for digital city.

Urban Real Estate in Ghana: A Study of Housing-related Remittances from Australia

A combination of rapid population growth and low incomes results in housing shortages in Ghana. Migration to Europe, America and Scandinavia has provided a way for some Ghanaians to escape this housing problem, as they take advantage of salaries there in order to save and build houses much quicker back home. This study of Ghanaian migrants in Sydney shows that by keeping at two or more jobs and saving about 33 per cent of their incomes, they are able to build houses worth US$100 000 in Ghana within 3–6 years. How these Ghanaians acquire land, how they build and their experiences after completing their houses provide clues on how to improve housing policy in Ghana.     

基于城市建筑垃圾物流管理信息系统开发的几点看法

介绍了建筑垃圾的界定与分类及其资源化利用途径;指出了建筑垃圾的资源化利用是一个系统工程,不只是简单地解决几个利用技术问题;提出了开发城市建筑垃圾物流管理信息系统的基本思想和步骤;给出了建立建筑垃圾管理系统的数学模型的思路和计算方法,从建筑垃圾资源化利用、循环经济的发展、可持续发展理念的深入等角度,论述了城市建筑垃圾物流管理信息系统开发的必要性与可行性。     

从"温州模式"到多中心城市群发展模式——以浙中城市群为例

改革开放以来,浙中地区在特定的经济、社会背景下,已逐步发展成以多中心为主要特征的城乡融合的浙中城市群。通过分析浙中城市群的特征、问题、背景和机制,明晰在强县扩权体制背景下、在"温州模式"的经济模式下,县域强中心、区域多中心的城乡融合发展模式的优越性。指出应将"小的是美好的"作为未来浙中城市群空间引导的核心理念,在浙江人多地少的宏观条件下引导城市空间的有机集聚,通过"TOD模式与串珠状发展空间、绿核与优质生活圈"等战略措施实现"城乡融合、整体融合"的空间引导目标。
