Regions and sustainable development: regional planning matters

This paper looks at how the term 'sustainable development' has been used in the process of regional plan making over the past decade. It emphasizes the differing geographies of these debates within England, in terms of how sustainable development has been used to justify different types of approach in different parts of the country. Both drawing on and challenging recent work on state theory, the paper argues the need to see regional planning as a part of a multi-scalar governance system, whose importance should not be underestimated.

Discourse,representation and urban planning: How a critical approach to discourse helps reveal the spatial re-ordering of street sex work1

This paper shows how a critical approach to discourse sheds light on processes of spatial re-orderings. It uses a case study of urban planning in an area of street sex work to explore the ways in which various representations of prostitution can be used to inform planning decisions. Representations of sex worker identity also expose complex spatial and social geographies and evolving processes of marginalisation and exclusion.

Public Participation in Planning: an intellectual history

This paper tracks the changing role of public participation in planning thought. In doing so, the paper shows that the role of public participation in planning is largely determined by the nature of the planning enterprise being undertaken. The definition of the planning problem, the kinds of knowledge used in planning practice, and the conceptualisation of the planning and decision-making context are the important determinants of the extent of participation offered to the public. The paper therefore contributes to thinking about how to evaluate public participation by showing that it can only be understood in terms of the decision-making context in which it is embedded. Specifically, it makes little sense to evaluate public participation in terms that are not shared by the planning model itself     

A hydraulic invariance‐based methodology for the implementation of storm‐water release restrictions in urban land use master plans

A hydraulic invariance (HI)‐based methodology was developed as a tool to support implementation of storm flow control measures into land use master plans (LUMPs) for urban catchments. The methodology is based on the use of simple hydrologic analysis to compare predevelopment and postdevelopment catchment flow release scenarios. Differently from previous literature examples, for which the parcel scale is usually considered for the analysis, HI was pursued assuming the LUMP areas of transformation as the basic units for assigning storm water control measures in the form of flow release restrictions. The methodology was applied to a case study catchment in the southern part of the City of Catania (Italy), for which the LUMP re‐design has been recently proposed. Simulations were run based on the use of the EPA‐Storm Water Management Model and allowed deriving flow release restrictions in order to achieve HI at the subcatchment level for design events of different return period.     

网络大数据下的中国现代食甜习惯空间分布特征及其影响因素研究

饮食地理文化作为地域文化中最具地方特色的重要元素,在现代人口大规模流动背景下呈现出全新的多样化局面,而基于传统认知的“南甜北咸”的地域分异已然不能代表中国现代食甜分布的空间特征。因此,本文采用网络爬虫技术,获取我国大陆31个省会城市共计约2000万条美食消费数据,从传统类菜品、主食类菜品、饮料类和甜品类菜品4个方面计算城市食甜度,在ArcGIS、MySQL软件支持下,借助GIS空间分析和数理统计方法探究我国现代食甜习惯的空间分布特征,分析影响食甜分布的因素。研究发现：① 中国食甜在空间分布上存在显著的地域分异特征,聚类分析评价参数R ²高达0.88,现代食甜习惯总体呈现“东高北中,西微内低”的包围式格局;② 从整体抑或局部角度,在1%显著性水平上莫兰指数均为正,中国食甜分布呈现显著的空间正相关关系,形成特色鲜明的3个地理集聚区,即以苏浙沪闽为主的东南沿海高甜集聚区,以渝黔川为主的西南内陆低甜集聚区和以陕宁为主的西北内陆低甜集聚区;③ 构建了中国现代食甜习惯分布影响因素模型,其拟合精度为0.82,分析结果显示降水、湿度、气温等气象要素及地理位置是影响现代我国食甜空间分布的重要因素。     

Assessing the effectiveness of imperviousness on stormwater runoff in micro urban catchments by model simulation

Imperviousness, considered as a critical indicator of the hydrologic impacts of urbanization, has gained increasing attention both in the research field and in practice. However, the effectiveness of imperviousness on rainfall–runoff dynamics has not been fully determined in a fine spatiotemporal scale. In this study, 69 drainage subareas <1 ha of a typical residential catchment in Beijing were selected to evaluate the hydrologic impacts of imperviousness, under a typical storm event with a 3‐year return period. Two metrics, total impervious area (TIA) and effective impervious area (EIA), were identified to represent the impervious characteristics of the selected subareas. Three runoff variables, total runoff depth (TR), peak runoff depth (PR), and lag time (LT), were simulated by using a validated hydrologic model. Regression analyses were developed to explore the quantitative associations between imperviousness and runoff variables. Then, three scenarios were established to test the applicability of the results in considering the different infiltration conditions. Our results showed that runoff variables are significantly related to imperviousness. However, the hydrologic performances of TIA and EIA were scale dependent. Specifically, with finer spatial scale and the condition heavy rainfall, TIA rather than EIA was found to contribute more to TR and PR. EIA tended to have a greater impact on LT and showed a negative relationship. Moreover, the relative significance of TIA and EIA was maintained under the different infiltration conditions. These findings may provide potential implications for landscape and drainage design in urban areas, which help to mitigate the runoff risk. Copyright © 2015 John Wiley & Sons, Ltd.     

基于公路交通网的旅游景区时间可达性分析——以武汉市为例

基于武汉市实际的公路交通网,利用Arc GIS空间分析工具和可达性模型,参考武汉市公路网结构,定量分析了武汉旅游景点的可达性及其空间格局。结果表明:景点分布空间上呈现出"大分散,小集中"的特点;武汉市旅游景区可达性呈现由中心向周边递减的圈层分布;区域内景点平均通行时间在0.723 8~3.003 5 h之间,景点可达性系数极差为1.766 6;受旅游景点空间分布、公路网结构及景点知名度的影响,旅游景区可达性空间格局不平衡分布较显著。最后,提出武汉市旅游空间结构优化的相关策略。
