江西省乡村聚落空间分布及评价

［目的］通过江西省乡村聚落发展及演变现状对其空间分布特征进行研究,并从乡村聚落发展优化的角度提出具体建议,对江西省乡村振兴战略实施具有重要的借鉴意义。［方法］运用GIS102操作平台对江西省乡村聚落空间分布情况以乡村聚落密度、乡村规模以及人口密度进行空间等级划分,通过计算最临近点指数、地理集中指数和地理联系率分析其空间分布特征。［结果］江西省市域和县域内的乡村聚落在乡村规模、人口密度以及聚落分布密度上存在较大差异,分布呈现不均衡的特点,且与经济发展和人口密度在空间上的均衡、配合程度较高。［结论］(1)江西省乡村聚落分布密度在空间上存在较大差异,形成以南昌市为中心,包含宜春市、萍乡市和上饶市大部分县域的北部密集区,主要为北部赣江流域下游平原和鄱阳湖平原地区,抚州市南部和赣州市大部分区域乡村聚落分布密度较小; (2)江西省乡村聚落在空间上整体呈集聚型分布且分布不均衡的特点; (3)其乡村规模较大的聚落多分布在上饶、赣州、九江和宜春等地,反映出江西省丘陵区和山地区的乡村聚落规模较大。     

北京城市绿地土壤水分入渗性能 研究

采用Guelph渗透仪注水法研究了北京市不同类型绿地的土壤水分入渗特征及其与质地、容重和孔隙度等土壤物理性质之间的关系。结果表明,北京市不同类型绿地土壤入渗速率差异较大,以文教区和居民生活区为最好,其后依次为公园、商业区、道路交通区。北京市绿地土壤质地以黏质土壤为主;相关性分析表明城市绿地土壤黏粒越少,土壤稳定渗透速率越快。北京城市绿地土壤由于受人为活动的影响,土壤物理性质发生了显著变化,表现为土壤容重增大,通气孔隙度降低,压实现象普遍。研究结果为北京城市绿地的规划设计和海绵城市建设提供科学依据。     

空间经济学的发展动态分析

20世纪90年代以来,新经济地理学的经济学家们把空间因素纳入到主流经济学的理论体系,经过多年的演进,空间经济学的总体框架已经基本形成。国内对于空间经济学的研究尚处于起步阶段,可喜的是我们已经看到一批重要的研究成果,而且空间经济学在中国蓬勃发展的土壤日益成熟。随着经济全球化的日益展开,全球范围内的空间问题变得更加凸显,区域间的相互影响、相互制约是空前的,它为空间经济学的发展提供了极佳的素材,空间经济学必将大有作为。     

赋权图的拓扑空间

本文对水路运输、交通运输中的赋权图定义了对应的拓扑空间,并讨论了相关的拓扑性质,证明了此类空间具有的强分离性质及紧性.对传统的Dijkstra方法进行改进,为最优化运输方案提出了一种算法,使得这种算法更容易理解和计算.     

旅游纪念品的市场空间研究

为合理的发展旅游纪念品的市场空间，首先分析旅游纪念品的价值特性，然后讨论旅游吸引物的关联体系对旅游纪念品市场空间的影响，进而揭示出它们对旅游纪念品市场空间的影响作用：旅游纪念品的市场空间有一定界限，但在一定条件下可以拓展，这种拓展具有方向性和向心性。     

The contests for power and influence over the regulatory space within the English professional football industry, 1980–2012

This study draws on the concept of ‘regulatory space’ to analyse the evolution of financial regulation of professional football clubs in England over the past 30 years. It begins by setting out the institutional context and, in particular, the internal governance structure of the Football Association. It then discusses three periods that demonstrate how the regulatory environment is characterised and shaped by different organisations, particularly the football authorities. It concludes by arguing that appropriate financial regulation is unlikely to occur under the following four circumstances: where internal governance structures of regulatory bodies are constituted in such a way as to inhibit the process of decision-making; where powerful actors maintain control of significant financial resources and have a desire to limit financial regulation; where minor actors do not have sufficient power and leverage; and where the government is unwilling to intervene and use legislation.     

城市女性就业的空间分布——以南京为例

女性就业问题是当前重要的城市社会问题之一,但目前从空间的角度对女性就业问题进行探讨的研究很少,忽视了就业与城市空间结构之间的关系。文章以南京为例,利用第五次人口普查的数据,分析了女性就业,包括制造业、服务业和行政管理业的女性就业在城区和郊区的空间分布和分异状况,并总结了女性就业的空间分布特征,即:在宏观空间层面上的中心化与在微观空间层面上的边缘化。     

Video teleconference use among geographically dispersed work groups: A field investigation of usage patterns and user preferences

Use of video teleconferencing (VTC) has been on the rise for several years, yet researchers have often discussed the failure of VTCs to support communication. The VTC facility at the MITRE Corporation is used more than would have been predicted by other research. Surveys were mailed to 300 MITRE employees who were known to have used our VTC facility or to have traveled (or both) during August of 1991. The survey asked respondents to describe at least one geographically dispersed work group of which they are a member, and it asked them to discuss how they choose among various approaches to communication, including holding face‐to‐face meetings and VTCs. Respondents felt that VTC is highly useful. It is best used for meetings that have little emotional content or requirements for interpersonal contact. The content of the meeting, however, was not the primary reason given for choosing between travel and VTCs. Cost and inconvenience of travel were cited as reasons for using VTC, and unavailability of VTC was cited as a reason to travel. Results are compared with those of conflicting studies.     

空间地上权与我国城市化进程

空间地上权制度在美日等国城市建设中应用十分广泛.然而,我国物权法虽已于第136条规定了空间建设用地使用权制度,但该项制度的应用实践很不充分,这显然与我国城市化进程很不相称.空间地上权在我国城市化进程中作用突出.它的导入,对于破解现代城市土地问题,促进土地资源有效利用,提高城市设施一体化水平,保护物业权利人利益以及削减事业费开支、增加国家空间使用费收入等,均具有十分重要的意义.
