公众参与城市绿色空间管理维护 ——以坦纳斯普瑞公园为例

“公众参与”广泛应用于以美国为代表的西方现代景观规划设计领域。随着社会的发展在美国等国相继出现“公众参与”城市绿色空间管理维护的趋势，人们逐渐意识到管理维护对城市绿色空间的重要性。以美国波特兰市坦纳斯普瑞公园为典型案例，通过实地调查、文献研究、访谈、归纳推理等研究方法，从公园建设背景、设计特色出发，回顾“公众参与”前管理维护的困境，阐述“朋友和伙伴”项目的发展历程、工作内容及成效，总结“公众参与”后期维护管理的意义，分析成功推行的原因。“公众参与”有助于解决目前中国城市公园管理维护面临的投入资金不足、游人素质偏低等问题，对未来城市公园管理工作的发展具有重要启示意义。     

基于地理学对"三江源"生态难民形成机制的分析

本文围绕“三江源”日益恶化的生态环境及由此引发的生态难民问题,从地理学的角度进行了综合分析,明确提出独特的自然环境系统和现代环境的变迁给源区牧民提供了极其狭小的空间,而人类活动中传统的生产方式、现代价值取向的变化、社会管理的失误以及落后的经济发展水平,无限制的对自然的索取,超越了环境系统所能承受的阀值,人类不得不听任自然的“安排”。因此,应通过合理规划,积极妥善地安置源区生态难民;调整产业结构,积极发展源区经济;科学管理,有计划地节制外来流动人员;发展教育,构建与源区生态相适宜的生态文化,实现区域可持续发展的“双赢”目标。     

Heritage as a motivation for four-wheel-drive tourism in desert Australia

Desert Australia is a vast, largely unpopulated area serviced by few roads. In recent years, tourism has been identified as an industry that has some potential to generate employment and investment opportunities in the region. Because of the distances involved and the largely unsealed road network that radiates off the main north-south highway much of the region is inaccessible to conventional vehicles. As a consequence, interest in four-wheel-drive (4WD) tourism has grown and a number of desert regions have identified this group as a potential market that could be further developed. One of the experiences that is associated with parts of desert Australia is its heritage values, both natural and built. This paper explores the role of heritage as a motivation to travel to desert Australia by four-wheel-drivers and the subsequent proportion of visitor expenditure that can be attributed to heritage tourism consumption. It concludes that while heritage is just one of many components of a 4WD trip, there may be substantial potential for increasing its economic contribution.     

Defensible Space on the Move: Revisiting the Urban Geography of Alice Coleman

This article traces the movement of the concept of ‘defensible space’ from New York City in the 1970s, where it was developed by the Canadian architect/planner Oscar Newman, to London in the 1980s and into design interventions in British public housing in the 1990s, through British geographer Alice Coleman, who acted as an especially powerful transfer agent. In focusing on this urban design ‘concept’ on the move we contribute to existing scholarship on policy mobility and city building in a number of ways. First, we explore an instance of the movement/mobility of a planning concept in a historical period (the recent past) largely overlooked to date. Secondly, we demonstrate that this movement was the result of a disaggregated series of expert knowledge transfers and localized translations of pre‐policy expert knowledge, generated through university‐based research work and networks. We theorize this instance of urban planning mobility by way of the interlinked insights offered by the sociology of science and policy‐mobilities literatures. As this is an instance of university research shaping public policy it also offers an opportunity to reflect upon the meaning of ‘evidence‐based policy’ and the impact agenda in contemporary higher education.     

解读艾丽丝·门罗小说的后现代主义特征

在国内的研究中,艾丽丝·门罗被认为是现实主义风格的代表人物,她的小说创作在观念和技巧上都超越了现实主义.通过门罗的两部小说《姑娘们和女人们的生活》和《你以为你是谁》,分析了门罗如何运用摄影艺术创作的特点,将陌生与熟悉,静态与动态之间的矛盾运用到她的后现代主义小说创作之中.     

基于实证研究的物流项目管理流程分析——以澳洲艾达铁路项目为例

现代项目管理应项目的需求而生,并在其传承的过程中得到了不断的发展。毫无疑问,项目管理对整个项目的成功起着举足轻重的作用,尤其对于大型基础设施建设项目而言,项目管理的执行效果往往直接影响着项目的最终绩效。作为澳洲在过去的50年里最大的运输基建项目,艾达铁路是通过良好的项目管理运作成功地完成了该项目生命周期之内各个环节的计划并最终实现项目整体成功的最佳范例。文章针对艾达铁路的项目管理进行了详细的分析和研究,以期能从艾达铁路成功的项目管理身上预见未来大型物流基建项目的发展趋势。     

Can environmental attributes influence protected area designation? A case study valuing preferences for springs in Grand Canyon National Park

Springs in Grand Canyon National Park (GRCA) provide water to over 6 million visitors per year. In addition to use value for visitors, springs have cultural value to indigenous peoples and provide critical habitat for plants and animals. Finally, base flow to the Colorado River is dependent upon springs and they also provide an important water source for backcountry recreation. Climate change, uranium mining, and increased groundwater pumping threaten the continued viability of Grand Canyon springs. Springs protection is at the forefront of proposed national policy to protect the area of the aquifers contributing to springs of the Grand Canyon outside of the designated boundaries of the national park. To date very little research on the non-market values of springs has been conducted, and no research has estimated non-market values of springs within Grand Canyon National Park using a Choice Experiment (CE). We conduct a nationwide online Choice Experiment to determine willingness to pay (WTP) to protect backcountry springs and attributes including; accessibility, suitability as a back country water source, suitability as habitat for species of concern, aesthetics, and significance to Indigenous Nations. We estimate a Bayesian mixed logit, and find an average willingness to pay of $32.60 per household for a spring with the presence of all five attributes. The habitat attribute produces the highest WTP of $14.80. We find WTP of $4.50 for springs with cultural significance. Results from our study could be instrumental in designation of the Grand Canyon National Heritage Monument. In addition, our results indicate that careful consideration of watershed services on public lands is essential for efficient decision-making regarding protection of public lands.
