对废弃非金属矿山的再次开发利用的优点

随着经济发展对建筑材料的需求促使非金属矿山的开采,随着矿山矿产资源的枯竭,一些矿山面临关闭,一般闭坑矿山需投入大量资金进行恢复治理。对于废弃非金属矿山再次开发利用可节约土地资源,优化矿产资源利用,且具有良好的经济效益,因此具有良好的前景。     

Ideas out of context and the contextualization of ideas: The transference of Jane Jacobs to São Paulo

The mobility and contextualization of urban policies between localities have received significant attention in recent literature. A number of mechanisms have been identified, including “best practices,” “policy tourism,” multinational firms, and conferences have been identified. This article identifies a new mechanism: the translation and publication of seminal theses into additional languages. Using citations analysis and interviews in São Paulo, this mechanism is confirmed as an additional mode of transference and identified as being responsible for the growth in interest in Jane Jacobs in São Paulo. However, this article finds that despite the increase in accessibility to her ideals, her emphasis on contextuality was overlooked in that case. This, in turn, calls attention to larger issues of the use of so-called ‘universally-good’ examples of urbanism.     

Sweet Auburn: Constructing Atlanta's Auburn Avenue as a Heritage Tourist Destination

Utilizing redevelopment plans created by Central Atlanta Progress, this study explores the process of constructing a heritage tourist landscape on Atlanta's Auburn Avenue. Once home to the wealthiest African American community in the United States, Auburn Avenue went through a period of economic decline in the 1970s and 1980s. In 2000, planners for the City of Atlanta focused on redeveloping the Auburn Avenue corridor. At that time, Central Atlanta Progress began to update plans to convert Auburn Avenue into the United States' premier African American tourist destination. Utilizing those plans, this article argues that the city's redevelopment vision ties into particular aspects of African American identity, which link to neoliberal economic policies in an effort to turn Auburn Avenue into a "culturetainment" district. This vision is juxtaposed against the reaction of community residents who seek an alternative redevelopment vision.     

传统旅游目的地再发展研究——肇庆案例

近年来,国内一些起步较早的传统旅游目的地,纷纷遭遇客源萎缩、产品老化、竞争不利等难题.为扭转局面,个别地方从政府主导的角度提出了很多策略或措施,如投巨资开发新产品、加大促销力度等,力求突破发展瓶颈.然而,如果以潜在游客的扩大和实际游客的增长为评判指标,这些策略和措施并非都适合于这些传统旅游目的地.通过对肇庆的案例分析发现,传统旅游目的地政府部门在出台再发展决策时,应当着力将不确定的发展"机会"转化为成熟的发展"条件",以规避风险,节约资源,争取成功.

Pop-up landscapes: a new trigger to push up land value?

Through a qualitative analysis of pop-up landscapes on Philadelphia’s Delaware Waterfront, this paper examines how entrepreneurial urban actors, such as municipal officials, urban planning agencies, and landscape designers, strategically harness to catalyze investment. While pop-up landscapes have disrupted negative associations with the waterfront, providing a space for people to reimagine the city and playing an active role as an integrative public space, the paper argues that there are reasons to be skeptical about the long-term goals the pop-up landscapes serve, given the widespread focus on real estate-led development.     

Clogging mechanisms and preventive measures in artificial recharge systems

Groundwater which occurs in fractured rock or porous aquifers or other geological weak zones such as faults and fractures is usually extracted via boreholes, hand wells or other sources such as springs.Water scarcity has become a severe problem due to many factors, such as an alarming increase in population and per capita water consumption, over exploitation of groundwater resources and abrupt global climatic change along with its related eco-environmental geological problems. In such situation, application of artificial recharge systems(e.g. surface recharge basin and deep injection well systems) can help to effectively manage and augment the unitization of groundwater resources. However, the clogging problem,which may be caused by a complex interdependent mechanisms of physical, chemical and biological has been a challenge for the efficacy and the implementation of recharge facilities. Clogging can reduce the permeability, recharge rate and longevity of recharge facilities and increase the operational and maintenance costs. Major influencing factors associated with the occurrence of clogging include the chemical composition of groundwater(both the recharge water and native groundwater), aquifer medium and microbial diversity, together with other environmental factors such as temperature, pressure, total dissolved solids, total soluble salts, pH, Eh, nutrients, gases, carbonates and others; these factors ultimately increase the piezometric head but reduce the permeability and infiltration rates of porous/seepage media.Pretreatment of recharge water can minimize the potential clogging. In the case of clogged wells,rehabilitation methods need to be deployed. In the meantime, there is an urgent needs to understand the basic causes and developmental processes/mechanisms of clogging in order to mitigate this problem. This paper reviews the major clogging mechanisms and their possible preventive measures and redevelopments in artificial recharge systems.
