城市群演化的空间过程及土地利用优化配置

城市群演化包含了诸多内容 ,如人口、产业、城市类型、城市职能等 ,而空间过程是最直接、最综合的表现。     

广州城市空间形态扩展中土地供应动力机制的作用

近 10年来呈剧烈变动状态的广州城市空间形态 ,刻烙着城市有机体内外部矛盾碰撞摩擦的痕迹 ,其中包含着权力行为力在空间的冲突过程。文中拟就从人文主义方法论的角度 ,以土地供应为中介媒体 ,研究分析它的供应机制对近 10年广州城市空间形态生长的影响 ,映视土地供应背后权力行为力对城市空间形态扩展影响的一般规律 ,以引导城市空间的健康发展     

位移监测在滑坡时空运动研究中的应用

滑坡时空运动特征是滑坡地质体在内因和外因共同作用下，自一种状态向另一种状态转化的地质过程。滑坡位移监测是研究滑坡变形影响因素、动态规律及预测预报的主要途径，特别是滑坡深部位移监测，又为研究滑坡体的时空运动过程提供了重要信息。本文结合几个滑坡的深部位移监测实践，综合分析位移监测信息，研究滑坡体的时空运动特征及发展趋势，为滑坡时空运动系统研究及稳定性预测提供依据。     

Religion and technology: refiguring place, space, identity and community

This paper reviews the literature on the religion–technology nexus, drawing up a research agenda and offering preliminary empirical insights. First, I stress the need to explore the new politics of space as a consequence of technological development, emphasizing questions about the role of religion in effecting a form of religious (neo)imperialism, and uneven access to techno-religious spaces. Second, I highlight the need to examine the politics of identity and community, since cyberspace is not an isotropic surface. Third, I underscore the need to engage with questions about the poetics of religious community as social relations become mediated by technology. Finally, I focus on questions about the poetics of place, particularly the technological mediation of rituals.     

The Space That Race Makes

This essay is a revision of a paper prepared for an NSF workshop on race and geography. Participants in the workshop were asked to offer their views on the topic and our suggestions for further research. This contribution explores some aspects of the relationship and relevance of geography to the question of race in North America. It touches on three “places” that constitute the discipline: the place of research, the place of teaching, and the workplace. With respect to research, it suggests some promising lines of inquiry. Among these are studies of the relationship of scale to the politics of identity and studies of “passing” in connection with studies of geographies of experience and geographies of power.     

模糊区域拓扑关系模型

拓扑关系是地理信息系统中空间要素之间最基本也是最重要的关系之一，是进行绝大多数空间查询和分析的基础。非模糊空间要素之间的拓扑关系在一般拓扑学等理论的基础上已有相关的模型和描述，并在实践中得到广泛的应用，如何建立模糊空间要素这间的拓扑关系是建立模糊要素地理信息系统的基础。该文在模糊扑扑学的基础上提出了模糊区域的定义，建立了用于分析模糊区域之间拓扑关系的理论和模型，提出了4*4-intersection模型拓扑关系矩阵，并分析了不同拓扑关系矩阵对于非模糊区域之间、模糊区域之间建立拓扑关系的区别和联系，最后采和不同公式对模糊区域之间的关系进行了系统的描述。     

The ins and outs of skateboarding and transgression in public space in Newcastle,Australia

This study examines skateboarding as a transgressive activity in different inner Newcastle public spaces, highlighting the way certain places are constructed, and the values and meanings attached to them. Skateboarding has been sanctioned in some places, but is considered to be inappropriate in others, resulting in the implementation of skating restrictions in specific areas. Transgressive conduct is different from the norm and appears to be ‘out of place’. However, labels of ‘in’ and ‘out’ of place are too simplistic, because transgression is more nuanced and can simultaneously operate at multiple scales. Some skateboarding activities and locations are seen as more legitimate than others, and so a skater can be both ‘in place’ and ‘out of place’ at the same time. Problems and inconsistencies in the regulation of public space are revealed, because although skateboarding may be illegal in some places, the regulations are blunted by limited enforcement, justified by distinctions between ‘good’ and ‘bad’ skateboarding.     

大洋多金属结核中1nm锰矿相的相变及其主要控制因素研究

多金属结核样品在室温中放置或加热干燥后 ,其中的 1nm锰矿相会部分或全部地相变为 0 7nm锰矿相 ,这说明 0 7nm锰矿相可能不是多金属结核的原生锰矿相 ,而仅仅是 1nm锰矿相的相变产物。研究结果表明 :1nm锰矿相结构中的Cu2 + 、Co2 + 、Ni2 + 等金属阳离子的含量与其结构稳定性有正相关关系 ,即金属离子含量越高 ,其结构越稳定 ,1nm锰矿相越不易相变为 0 7nm锰矿相 ,反之亦然 ;另外 ,不同金属阳离子稳定 1nm锰矿相结构的能力也不同 ,结核中几种主要金属阳离子对 1nm锰矿相结构的稳定能力从大到小为 :Ni2 + >Cu2 + >Co2 + >Zn2 + >Ca2 + =Mg2 + 。
