Neighbourhoods and public service boundaries in the city: a geographical analysis

Recent trends towards local democracy and increased citizen-participation in the process of urban government and management would clearly be aided if the boundaries of neighbourhoods and administrative, political and service areas were coincident. This paper seeks evidence for such correspondence, based on an empirical investigation in Glasgow, and concludes that a reformulation of polling districts offers the greatest potential for approaching this objective.     

加强地下管线档案信息化管理为城市规划、建设和管理发挥基础作用

地下管线是城市基础设施的重要组成部分，是城市赖以生存和发展的物质基础，被称为城市的“生命线”。掌握和摸清城市地下管线的现状，是城市规划、建设和管理的需要，是抗震、防灾和避免管线事故的需要，是保证城市人民的正常生产、牛活和城市发展的需要。     

城市建设对温泉的影响评价——以巢湖半汤为例

城市建设必然对地质环境产生影响,但城市建设对温泉水文地质条件的影响评价研究极少。本文以巢湖半汤为例,在地质调查的基础上,将温泉组成划分为补给区、径流通道和排泄区。分析了城市建设对温泉的影响因素,并分别评价了这些因素对温泉各组成部分的影响。评价结果表明巢湖半汤规划区城市建设总体上对温泉影响较小。     

城市地下管线规划建设管理中存在的主要问题与对策--访中国城市规划设计研究院城市水系规划设计研究所宋兰合所长

对我们的供水管网来讲，配水管网最终布局要通过几个步骤，第一对整个城市的用水量进行预测；第二在预测增长量的基础上对于原有系统统一做一个水量的平衡；第三在此基础上进一步规划工程的规模；第四个步骤是水源论证；第五、第六是取水工程和净水下程涉及到工程技术问题；第七个步骤是输水工程，主要是源水的输送。最终我们是根据以上儿个步骤，对配水管网在城市空间上的一个整体的布局。对于污水系统，第一步要确立排水体制，现在来讲，规模以上的城市以及新建的城限是要求雨污分流的，但在一些具体的地方，可能对于雨污分流的具体的方式会有所不同。第二步是要根据我们城市的一个建设的布局和用水量估算污水。第三步是污水处理场的规划选址问题。第四步根据排水量和处理厂的布局进行污水管系统的定线。雨水系统：第一步径流设计，第二步泄水区划分，第三步对于管（渠）系统进行布置。这是管网现在规划的现状。     

Advance,deglacial and sea‐level chronology for Foxe Peninsula,Baffin Island,Nunavut

The impact of the Laurentide Ice Sheet (LIS) deglaciation on Northern Hemisphere early Holocene climate can be evaluated only once a detailed chronology of ice history and sea‐level change is established. Foxe Peninsula is ideally situated on the northern boundary of Hudson Strait, and preserves a chronostratigraphy that provides important glaciological insights regarding changes in ice‐sheet position and relative sea level before and after the 8.2 ka cooling event. We utilized a combination of radiocarbon ages, adjusted with a new locally derived ΔR, and terrestrial in‐situ cosmogenic nuclide (TCN) exposure ages to develop a chronology for early‐Holocene events in the northern Hudson Strait. A marine limit at 192 m a.s.l., dated at 8.1–7.9 cal. ka BP, provides the timing of deglaciation following the 8.2 ka event, confirming that ice persisted at least north of Hudson Bay until then. A moraine complex and esker morphosequence, the Foxe Moraine, relates to glaciomarine outwash deltas and beaches at 160 m a.s.l., and is tightly dated at 7.6 cal. ka BP with a combination of shell dates and exposure ages on boulders. The final rapid collapse of Foxe Peninsula ice occurred by 7.1–6.9 cal. ka BP (radiocarbon dates and TCN depth profile age on an outwash delta), which supports the hypothesis that LIS melting contributed to the contemporaneous global sea‐level rise known as the Catastrophic Rise Event 3 (CRE‐3).

推进城乡建设标准化事业健康发展

工程建设标准是为在工程建设领域内获得最佳秩序，对各类建设工程的勘察、规划、设计、施工、安装、验收、运营维护及管理等活动和结果需要协调统一的事项所制定的共同的、重复使用的技术依据和准则，它以科学技术和实践经验的综合成果为基础，以保证工程建设的安全、质量、环境和公众利益为核心，以促进最佳社会效益、经济效益、环境效益和最佳效率为目的。     

Utilizing crowdsourcing to enhance the mitigation and management of landslides

Landslides are mainly triggered by earthquakes and rainfall and have poor temporal predictability. Landslides pose significant threats to settlements and infrastructure in mountainous regions around the world. To mitigate this natural hazard, a new paradigm of landslide mitigation and management is required. Increasing smartphone ownership around the world, especially in developing countries, offers scientists an opportunity to embrace crowdsourcing so as to improve landslide research. This paper presents a new landslide information system (LIS) comprising a smartphone app and an administrative interface and database. The mobile app has been published for both iPhone and Android platforms. The interface of the smartphone app is powered by the highly-customizable Google Maps platform, which is overlaid with real-time landslide data. Users can choose between visualizing “known sites” and “contribution” of landslide data. The visualization option shows published landslides and areas that are susceptible. Users can contribute their GPS coordinates and multimedia to enhance landslide reports. A comparison with similar systems, potential applications, and challenges of using smartphone technology for mitigating landslides are also discussed.     

Integrated methods and scenario development for urban groundwater management and protection during tunnel road construction: a case study of urban hydrogeology in the city of Basel,Switzerland

In the northwestern area of Basel, Switzerland, a tunnel highway connects the French highway A35 (Mulhouse–Basel) with the Swiss A2 (Basel–Gotthard–Milano). The subsurface highway construction was associated with significant impacts on the urban groundwater system. Parts of this area were formerly contaminated by industrial wastes, and groundwater resources are extensively used by industry. During some construction phases, considerable groundwater drawdown was necessary, leading to major changes in the groundwater flow regime. Sufficient groundwater supply for industrial users and possible groundwater pollution due to interactions with contaminated areas had to be taken into account. A groundwater management system is presented, comprising extensive groundwater monitoring, high-resolution numerical groundwater modeling, and the development and evaluation of different scenarios. This integrated approach facilitated the evaluation of the sum of impacts, and their interaction in time and space with changing hydrological boundary conditions. For all project phases, changes of the groundwater system had to be evaluated in terms of the various goals and requirements. Although the results of this study are case-specific, the overall conceptual approach and methodologies applied may be directly transferred to other urban areas.
