北京市区轨道交通对周边住房租赁价格的影响分析

基于北京市六环内住房租赁样本的交易数据,本文以北京地铁为例,采用空间回归模型实证探讨轨道交通对合租和整租这两种不同方式下的住房租赁价格的影响。结果表明：①基于轨道交通的就业可达性对于租赁价格会产生显著的增值效应,租客愿意为就业可达性较好的住房支付溢价租金。②地铁站点密度对整租的租赁价格具有正向影响,对合租无显著影响,而地铁换乘线路变量未对租赁价格产生显著影响。③轨道交通对合租和整租住房租赁价格的影响随着距离增加呈现差异化的演变规律。合租方式的租赁价格的影响随着实际路网距离的增加呈现单调递减,距站点500m范围内影响最大;而整租方式呈现倒“U”形变化,在500-1500m范围内增值效应最大。针对研究结果,建议政府加大租赁住房供给的同时要充分考虑轨道交通要素,精准施策以实现公共资源的空间高效配置。     

历史时期疏勒河水系变迁及相关问题研究

疏勒河是河西走廊西部的重要河流,关于历史时期其水系的演变问题,前辈学者已从不同角度予以关注,但在方法与详尽程度方面仍有较大改进空间。本文在充分发掘地方文献的基础上,充分利用游记、考古材料,并结合自然科学相关研究成果,就历史时期各阶段疏勒河流域水系分布状况与演变过程进行了全面讨论,订正了一些广为流传的明显错误,并就其中涉及到的部分古代地名问题提出了自己的看法。     

古代文物丝织品霉斑清除的研究

为了解决故宫博物院库房藏品中部分古代丝织品出现生霉的问题,从对库藏纺织品的病害现状调研入手,了解生霉文物本身的质地、染料成分、以及霉斑形成的环境状况,利用改进的改良型超声清洗方法和弱酸化水溶液,对多件霉变石青色丝织品进行了清洗处理,获得了满意的效果,此法可以在今后的工作中加以推广。     

What if Edward Abbey's “Monkey Wrench Gang” had Succeeded? The Ghosts of Glen Canyon Past,Present, and Future

Across the fiction and non‐fiction writings of Edward Abbey (1927–1989), the anticipated restoration of Glen Canyon on the Colorado River is a recurring theme. This article employs Abbey's polemic for the removal of Glen Canyon Dam to critique contemporary debates on dam decommissioning, water politics, and ecological restoration in Glen Canyon on the Utah–Arizona border. The endeavours (and fantasies) of Abbey's fictional quartet of eco‐saboteurs reveal his radical and anarchical imaginings on how to remove the dam, yet his non‐fiction works often suggest why Glen Canyon should be restored. The politicisation of Abbey's philosophy is explored through (1) organisational, institutional responses to the question of draining Lake Powell reservoir and decommissioning the dam, and (2) how the ideology of Abbey's fictional gang is recast—and plays out—in the actions of environmental activists. This article argues that Abbey remains an important voice in the battle to restore the Glen.     

The post‐politics of transport: establishing a new meeting ground for transport politics

This paper brings together two disparate but critical bodies of literature about contemporary citizen participation in the Australian city: transport politics and post‐politics. The argument is advanced that state and citizen actor relations—as they exist in the governance and management of Australian urban transport—have taken on characteristics of post‐politics. By conceiving of citizen participation in this manner, new ways of understanding it are generated and it is possible to appreciate how such participation is shaped by state actors both across time and in response to the politicisation of transport proposals. The paper illustrates the extent to which citizen engagement has become a new focal point in transport politics, particularly given citizens' capacities to politicise proposals and transport trajectories. It achieves such ends by drawing upon key‐informant interviews conducted between 2013 and 2016 with public transport advocates, select resident groups, and local and state level planning officials from Melbourne, Australia.     

长株潭城市群城镇化进程与水资源利用响应关系研究

采用层次分析法与熵权法相结合的方法,构建长株潭城市群城镇化综合发展水平和水资源开发利用综合潜力评价指标体系及响应关系模型,对2001-2015年间研究区域城镇化发展进程与水资源利用之间的动态过程进行定量研究,分析主要影响因素、变化特征以及两者响应特征。结果表明：长株潭城市群处于快速城镇化和规模扩张阶段,人口城镇化和空间城镇化水平高于经济城镇化和社会城镇化水平,城镇化发展质量有待提升;区域用水负荷逐年增加,虽然水资源利用效率和管理水平稳步提升,但水资源自然禀赋和开发利用程度受区域水文条件的影响显著。在2001、2005、2007、2009、2011年,长株潭区域城镇化的发展在一定程度上受到水资源系统的约束。协调好城镇化与水资源之间的关系,必须改变规模外延扩张模式,以控制水资源总量、有效提高水资源利用效率为目标,减弱水资源系统对城镇化发展的制约,提高水资源保障能力。     

空铁型综合交通枢纽地区空间演化特征——以上海虹桥枢纽为例

空铁型综合交通枢纽是将航空枢纽和高铁枢纽有机整合而形成的航空高铁一体化综合交通枢纽,具有较强的经济社会带动作用,对区域空间演化产生重要影响。根据复杂适应系统理论,选取上海虹桥综合交通枢纽地区为案例地,分析了空铁型综合交通枢纽地区地域空间演化阶段性特征。结果表明：交通枢纽地区地域系统通过多个适应性主体之间非线性相互作用形成复杂适应系统,该地域系统演化过程可划分为枢纽地区空间形成阶段、枢纽地区空间生长阶段和枢纽地区空间涌现阶段。上海虹桥综合交通枢纽地区在三个阶段特征不同,配套设施建设、要素集聚与流动、城市功能形成与发展、区域品牌形成等方面不断深化。研究有助于认知综合交通枢纽地域系统空间演化规律,为深化研究和实践发展提供科学借鉴。     

Fruits in foundation deposits of two temples

Foundation deposits underneath the walls of two temples near Semna, Sudan (c. 1500-1480 BC), included dried plant material. Five fruit species are represented: Vitis vinifera (grape), Ficus carica (fig), Citrullus vulgaris (water melon), Phoenix dactylifera (date) and Ziziphus spina-christi. Of particular interest are the remains of tubers of Cyperus esculentus. The plants mentioned above are known as funeral gifts in Egyptian tombs.
