GIS技术在萨拉乌苏考古遗址公园规划设计中的应用   总被引:1,自引:0,他引:1  
传统规划设计工作的技术平台多以计算机辅助设计(CAD)为主,本工作以内蒙古自治区鄂尔多斯萨拉乌苏考古遗址公园规划为例,将Arc GIS Desktop作为技术平台应用到公园的规划设计工作中。首先,通过对规划区的实地踏勘,采集相关数据和资料,进行规划区数据库建设;其次,在数据库建设的基础上,通过GIS技术构建与现实环境对应的虚拟地理信息空间,实现规划区景观的三维可视化;最后,利用三维景观模型对现实地理环境进行模拟、分析及虚拟场景飞行。不同于传统CAD的二维工作平台,本工作借助GIS对空间数据和属性数据的强大处理功能及其三维景观可视化模块,为实现内蒙古鄂尔多斯萨拉乌苏考古遗址公园的科学规划提供辅助。  相似文献

While rights and freedoms of sexual citizenship have been foregrounded in geography, vaguer attention has been given to questions of political obligation. Feminist work on political obligation, grounded with a framing in political ecology of disease, however, provides a means to correct this neglect. Empirically, I narrate a story of local public health politics in Seattle, WA. There, a cultural panic played out in the media over the alleged failure of political obligations by gay men around sexually transmitted infections. Political obligation and ecology usefully extend the concept sexual citizenship on its own terms by moving beyond a rights-versus-obligation polarity, highlighting the biophysical realities of sex, recognizing the spaces in which sex occurs, and noting the social relations inherent in sex and sexuality. Thus, this paper contributes to deeper thinking for activists involved in working through these questions as well as bolstering the notion of sexual citizenship in political geography.  相似文献

After enjoying considerable success among French scholars, the concept of regulation has now become one of the main political arguments for explaining and justifying policy. Paradoxically, the success of regulation owes more to its ambiguity than to its suitability to actual policy and political goals. In order to understand the elements comprising the French regulation discourse, it is necessary to examine both its historical roots and the conditions for its diffusion and hegemony. It is also important to distinguish at least two very different domains within which such discourse is applied. The first relates to macroeconomic policy that, for several reasons, faced the most fundamental ideological and practical transformations. The second relates to territorial policy, which is simultaneously confronted with the reform of public intervention and new spaces of European regulation. The focus on French structural policy implementation will highlight France’s peculiar way of negotiating between two new norms of regulation: subsidiarity and regionalisation. The story behind these two concepts shows general similarities, but also reveals interesting differences such as the methods employed to legitimise new regulations, their linearity and ruptures, and the degree of coherence of the new dominant discourses. This paper draws some lessons from the French case to assess the new role set for European regulation.  相似文献

This paper investigates the critical role of workers to enhance the resilience of water supply services in cities at war through analyzing the case of Madrid and the Madrid water company Canales del Lozoya during the Spanish Civil War (1936–1939). We argue that securing the protection of vital urban flows mediated through infrastructures is a key objective of cities under attack. In doing so we contend that examining how those affected by the interruption of these flows cope with the situation represents a valuable but largely neglected form of water management. We illustrate how quotidian knowledge about the urban geography of water flows may have important repercussions for the war effort itself. In a nutshell, the case of Madrid offers an early account of the critical role of water workers in sustaining “urban ecologies under fire” securing the complex urban metabolism while also contributing to the struggle against invading forces.  相似文献

Whether Americans have “sorted” into politically like-minded counties and to what extent is hotly debated by academic and journalists. This paper examines whether or not geographic sorting has occurred and why it has occurred using a novel, dynamic analysis. Our findings indicate that geographic sorting is on the rise, but that it is a very recent phenomenon. In the 1970s and 1980s, counties tended to become more competitive, but by 1996 a pattern of partisan sorting had emerged and continued through the present. Results suggest this pattern is driven by Southern re-alignment and voting behavior in partisan stronghold counties. Lastly, we find evidence that migration can drive partisan sorting, but only accounts for a small portion of the change.  相似文献

The concept of the ‘counter-movement’ has had a significant impact within studies in International Political Economy (IPE). In the light of the credit crisis and the growth of growing resentment to the notion of the free market, the idea of the counter-movement has been utilised to understand social reaction to neoliberalism. This article argues that whilst the counter-movement has been used in unique and innovated ways, Karl Polanyi himself used the term largely to refer to a specific period in nineteenth-century British history. This article argues that whilst the counter-movement remains interesting, its application remains open to scrutiny. It questions whether the concept was indeed central to Polanyian economic thought and how much can be given to it in today's contemporary era of neoliberalism. It also suggests that by focusing merely on the counter-movement, Polanyian accounts within IPE are in danger of ignoring much of his wider critique of market economics.  相似文献

The nonlinear seismic response of base-isolated framed buildings subjected to near-fault earthquakes is studied to analyze the effects of supplemental damping at the level of the isolation system, commonly adopted to avoid overly large isolators. A numerical investigation is carried out with reference to two- and multi-degree-of-freedom systems, representing medium-rise base-isolated framed buildings. Typical five-story reinforced concrete (RC) plane frames with full isolation are designed according to Eurocode 8 assuming ground types A (i.e., rock) and D (i.e., moderately soft soil) in a high-risk seismic region. The overall isolation system, made of in-parallel high-damping-laminated-rubber bearings (HDLRBs) and supplemental viscous dampers, is modeled by an equivalent viscoelastic linear model. A bilinear model idealizes the behavior of the frame members. Pulse-type artificial motions, artificially generated accelerograms (matching EC8 response spectrum for subsoil classes A or D) and real accelerograms (recorded on rock- and soil-site at near-fault zones) are considered. A supplemental viscous damping at the base is appropriate for controlling the isolator displacement, so avoiding overly large isolators; but it does not guarantee a better performance of the superstructure in all cases, in terms of structural and non structural damage, depending on the frequency content of the seismic input. Precautions should be taken with regard to near-fault earthquakes, particularly for base-isolated structures located on soil-site.  相似文献
