Land-Parcel Land-Use History as a Key to Site Selection for Documenting Soil Contamination Risk： a Case Study from Australian Suburbia     

YU Jie Ursula Pietrzak Jim Peterson 《地球空间信息科学学报》2005,8(4):257-261

In that orcharding in early-to-mid twentieth century southeastern Australia involved use of certain heavy metal and As compounds in regular pest-control spray procedures, some interest attaches to the possibility that these landparcels are underlain by soils with above-background Cu, Pb and As levels. Interpreta- tion of Land-cover changes allowed land parcels previously occupied by orchards to be identified in the 1950s through time-series air-photos. A comparison of soil analysis results referring to soil samples from control sites, and from land parcels formerly occupied by orchardists, shows that contamination （above-background） levels of cations in the pesticides can be found in the top 6 cm of former orchard soils. It is clear that digital spatial data handling and culturally-informed air photo interpretation has a place in soil contamination studies, land-use planning （with particular reference to re-development） and in administration of public health.  相似文献

The worlds of tea and coffee: Patterns of consumption     

David Grigg 《GeoJournal》2002,57(4):283-294

Coffee and tea are both drunk in most countries, but typically one predominates. Coffee is the preferred drink in Europe and the Americas, tea elsewhere. Until the early eighteenth century coffee production and consumption was confined to the Islamic world, tea production to East Asia. European traders altered this pattern dramatically. The present pattern of coffee consumption is influenced by income per capita, that of tea is not. Religious influences played some part in the early development of both tea and coffee but have little relevance at the present. National factors have influenced wider patterns. British preference for tea was taken to all their colonies. In recent years fears about health have had some influence on coffee consumption. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献   

Agents of Eviction: The Squatter Control and Clearance Division of Hong Kong's Housing Department     

Alan Smart 《Singapore journal of tropical geography》2002,23(3):333-347

More is known about the policies that produce forced evictions and their consequences than about the agencies whose responsibility it is to conduct them. Understanding the nature of forced evictions requires greater comprehension of responsible agencies since the ways in which they implement policies may be a crucial intervening variable influencing the outcomes. In this paper, I use documentary and ethnographic research to describe the Squatter Control and Clearance Division of the Hong Kong Housing Department. Responsible both for evicting squatters and for controlling squatter areas that are permitted to remain for the time being, officers must respond to the conflicts and challenges of their twin, partially conflicting, mandates. Examination of changes in squatter control and clearance practices since 1954 is followed by a brief case study of the most recent squatter clearance that occurred in July 2001.  相似文献   

Placing geographies of public health   总被引：6，自引：0，他引：6  

Tim Brown  & Craig Duncan 《Area》2002,34(4):361-369

Following the move to a 'post–medical' geography, a large amount of research has come to focus on public health issues. This paper explores these current geographies of public health and argues for the development of a more critical perspective. In particular, it draws on commentary that has emerged out of debates that have taken place within a body of literature usually identified as the critical 'new' public health. The paper goes on to argue that such scholarship offers crucial insights for the production of a critical geography of public health.  相似文献   

Public environmental information: understanding requirements and patterns of likely public use     

Mordechai Haklay 《Area》2002,34(1):17-28

Public access to environmental information received much attention in the last decade. Recent developments promote access to this information through public telecommunication networks. This paper describes a Web-based survey that explored the requirements and needs of likely users of public environmental information systems for London: educated middle-class members of the public, with high interest in environmental issues and computer literacy. The survey demonstrated current information consumption patterns and the reasons to gather and use such information.  相似文献

中国环境影响评价中公众参与的有效性有待提高   总被引：3，自引：1，他引：3  

刘衍君  吴仁海 《云南地理环境研究》2003,15(3):28-32

环境影响评价(EIA)作为协调经济发展与环境保护的手段，已日益成为国家环境管理的重要工具。公众参与是环境影响评价的重要组成部分。从公众参与的概念及作用出发，分析中国环境影响评价中公众参与的机制，认为存在着参与对象选取不合理、参与形式双向性差、调查内容设置不科学、意见整理分析方法不完善及公众参与时段滞后等影响公众参与有效性提高的问题，最后提出注重参与对象的代表性，形式的有效性，内容的科学性，分析的定量化以及权利的保障等，以提高中国环评公众参与的有效性。  相似文献
