论我国城市开放空间系统的优化 总被引：14，自引：2，他引：14
城市开放空间系统优化是强化生态城市建设,进而推动城市可持续发展的重要途径。本文讨论了我国城市开放空间系统优化的重大意义,指出:城市的可持续发展强烈呼唤生态城市建设,而生态城市建设必须以城市开放空间系统的优化为支撑。解析了城市开放空间系统的空间形态结构和要素组成结构,阐明了开放空间系统的实用功能、生态功能、文化功能、景观功能和调控功能等,提出了城市开放空间系统优化的理论基础和应遵循的基本原则。在此基础上,着重论述了城市开放空间系统优化的基本对策和空间布局结构优化、圈层一体化优化、系统要素优化等主要工作内容。 相似文献

Jason Dittmer 《International Journal of Cultural Policy》2013,19(2):119-138
The cultural policy of the European Union (EU) has become more important than before as economic crisis threatens to undermine the EU’s nascent political identity. This paper offers graphic narrative (or comics) as a medium particularly suited to the task. This suitability results from several features: (1) the text/image hybridity of comics, which eases translation into multiple languages; (2) the topological aspect of graphic narrative, in which panels compose a spatial network of relations of various intensities that is isomorphic with the theorization of European space offered by a key EU think tank; and (3) the potential for comics of the ‘everyday’ to narrate a plural, non-didactic identity with which both Europeans and others can identify. It is hoped that a policy such as this could have a more positive influence on the more territorial, exclusive notions of the EU. 相似文献

我国农村救护车资源布局优化:以河南省郸城县为例 总被引：1，自引：0，他引：1
优化农村救护车资源的配置有助于缩短急救服务的响应时间,对于维护重症伤(病)员的生命安全具有重要意义。本研究以河南省郸城县为例,将15分钟作为急救车路上所需响应时间,研究了该县当前救护车资源布局下农村居民的可达性;应用ArcGIS中的p-中位模型优化了郸城救护车布局点,并运用SPSS16中的配对样本t检验对比了优化前后郸城居民救护车服务可达性变化;应用ArcGIS中的最小覆盖面模型求解了覆盖郸城县域所需的最少救护车布局点数。研究显示,通过优化能有效提高居民的救护车资源可达性,在县域范围内布局13个左右的救护车资源能基本覆盖所有居民点。这一数量对与郸城具有相似自然社会背景的黄淮海平原县域具有借鉴意义。最后,文章还讨论了研究存在的局限。 相似文献

基于引力模型的城际交通网络布局规划方法研究 总被引：1，自引：0，他引：1
交通网络的发展是城镇体系空间完善的重要条件。根据城镇体系空间特点和经济社会布局,制定与之相适应的城际交通网络布局规划,是路网规划的重要组成部分。本文在分析城际交通网络布局与经济及产业布局、城镇体系布局的关系基础上,结合交通网络的特征,提出了基于引力模型和拓扑结构的城际交通网络布局规划方法,并结合湖北省城际高速公路网布局规划开展了实证研究,对该省2015年城际高速公路网的布局模式进行了预测,并就高速公路网络的发展特征与城际经济社会空间联系的关系进行了分析。 相似文献

Abstract: Multi‐scalar or multi‐site power relations offer two contrasting ways of understanding the shifting geography of state power. In this paper, we argue for a different starting point, one that favours a topological understanding of state spatiality over more conventional topographical accounts. In contrast to a vertical or horizontal imagery of the geography of state power, what states possess, we suggest, is reach, not height. In doing so, we draw from Sassen (2006 , Territory, Authority, Rights: From Medieval to Global Assemblages, Princeton University Press) a vocabulary capable of portraying the renegotiation of powers that has taken place between central government in the UK and one of its key city regions, the South East of England; one that highlights an assemblage of political actors, some public, some private, where negotiations take place between elements of central and local actors “lodged” within the region, not acting “above”, “below” or “alongside” it. The articulation of political demands in such a context has less to do with “jumping scale” or formalizing extensive network connections and more to do with the ability to reach directly into a “centralized” politics where proximity and reach play across one another in particular ways. 相似文献

AbstractResearch on tourism enclaves has relied mainly on topographical understandings of the phenomenon. The focus has been on the ontic, that which is or exists instead of the relational qualities or properties of tourism enclaves. Topographical conceptions thus tend to simplify enclavic processes and attributes that are much more complex than meets the eye. In this article, we make the case for topological understandings of tourism enclaves, based on a relational ontology, as a complement. We thereby strive to offer more nuanced conceptions of tourism enclaves. We depart from Agamben’s political ontology to illustrate our claim. Seen topologically, tourism enclaves are not simply spaces marked-off from the norm, but rather constituents of the norm. Tourism enclaves need to be theorized as ‘prototypes’ or ‘laboratories’ of new subjectivities (ways of being, relating, and experiencing the world). The tourist thus emerges as a model figure of biopolitics in the contemporary, the norm rather than the exception. The tourist is not that which is abandoned by the sovereign in the manner of Agamben, but rather a free exilant, a subject that self-willingly chooses abandonment. We deploy topological concepts, like Agamben’s the ban, the camp, and state of exception. Such a conception, we argue, widens the ontological register or horizon of tourism theory. 相似文献

ABSTRACT International development aid has in recent years sought to strengthen youths’ societal participation by cooperation between international non-governmental organisations (INGOs) and local youth associations. In this paper, we address and conceptualise some of the underlying causes that may enable and/or limit such efforts to support youth participation in the global south. We seek to contribute to the growing literature exploring the multiple scales of young people's political agency. A core argument proposed is that notions of generational relationality, as seen in the case of international development aid targeting youth, must include conceptions of power as a topological relation across space. 相似文献

Interpersonal conflict poses a serious threat to social justice activism. In the context of indigenous solidarity activism in southern Arizona, conflicts are often born of the challenges accompanying differentials in social privilege due to differences in race and ethnicity relative to white supremacist settler colonialism. This paper examines activist collaboration between Tohono O'odham and non‐Native anarchist activists in southern Arizona, arguing that a topological activist polis is a useful lens through which we can better understand the roots of conflict in social justice activism. Non‐Native activists are often aware of the ways white supremacist settler colonial society privileges particular identities while marginalizing others. Nonetheless, settler and white privilege give rise to tensions which can be seen topologically through the very different relationships non‐Native and indigenous activists have to ongoing processes of white supremacy and to histories of the genocide of indigenous peoples. 相似文献
