中国乡村城市化浅析   总被引:1,自引:0,他引:1  
实现乡村城市化是我国21世纪实现工业化、现代化重要战略布置,也是我国经济社会发展面临一项十分紧迫的任务。正如马克思在《政治经济学批判》中指出:“现代的历史是乡村城市化,而象古代那样,是城市乡村化。”因此,寻求一条适合我国国情和地区特征乡村城市化道路,探索我国乡村城市化发展的战略思想,是当代城市规划工作面临的一个严峻课题,也是制定跨世纪城市规划的重要组成部分。  相似文献

工程施工计划是一项复杂的工作,不断增长的复杂因素决定了工程管理人员需要采取新的、从未被用过、检测过的工程施工方法。缺乏便于工程策划人员进行评估和确认施工计划是否合理的工具,会在工程施工阶段造成许多重复性工作,造成成本浪费。虚拟现实技术为解决上述问题提供了一个很好的方法,会生成虚拟环境,允许项目决策人员在施工之前合理优化和选择施工方案,资源优化,降低成本,从而获得更好的投资效益。利用群体支持系统建立与工程施工计划相呼应的模型,工程数据作为其处理问题与人机交互的依据,辅助人员决策,进行项目的预算和分析,提高工程项目的价值管理。  相似文献

Land exploitation, as an important strategy to mitigate farmland loss and stabilize grain production, has been adopted to compensate farmland loss due to rapid urbanization in China. Bounded by the limited capacity and obvious spatial variations of national farmland reserves, it is essential to arrange land exploitation activities timely and reasonably. In this study, we propose an indicator for the status of regional land exploitation, the Exploitation Degree, to facilitate an overview of land exploitation programs in China at both provincial and prefectural levels based on project data from 2006 to 2012. To further our understanding of the regional features of land exploitation activities, we employ the Lasso model to identify and quantitatively assess influencing factors on land exploitation. Our study shows that: (1) contemporary land exploitation practices in China are significantly inconsistent across exploitable farmland reserves. Some areas are greatly over-exploited and such irrational land exploitation has been persistent; (2) related national land plans designed to guide land exploitation efforts centered on resource-rich regions and critical areas do not function as intended. Therefore, we suggest that China⿿s land exploitation policy shall be improved by reconsidering the orientation of land exploitation policy, coordinating land exploitation activities with productivity improvements and eco-system protection, and enhancing the power and scope of the plans in controlling and guiding land resource management.  相似文献

This paper explores how culinary texts operate in both performative and transformative senses in relation to wider societal norms of gender and cultural capital. As such, the paper explores changes to the way in which the culinary consumer is presented in British Italian cookbooks from 1954 to 2005. Across the period, we see a shift in the gendered representation of the culinary subject, from a housewife in the period 1954–1974, to a working mother from 1975 to 1986, and most recently as male or female cook from 1987 to 2005. We also see shifts in representation of cultural capital in these same periods from learning new cooking skills, to adapting existing cooking skills to displaying skills in shopping and product selection. In charting these changing discourses, we find that whilst reflecting wider culinary culture, these cookbooks also act in a transformative sense to promote (and indeed require) specific enactments of gender and cultural capital.  相似文献

In the past few decades, urbanisation has become a major phenomenon in European cities, thus representing one of the key human land cover changes with socio-economic and environmental impacts. In the Lisbon metropolitan region it is estimated that 17% of natural and farmland have been transformed into artificial areas. Since the end of 1990s, specific EU guidelines have been issued to contain urban sprawl and preserve agricultural land. Spatial planning in Portugal obviously is integrating these assumptions into the statutory land-use master plans. But what is the performance of this land use planning system regarding land cover evolution itself? Based on the Lisbon metropolitan region (LMR), one of the major areas of urban growth in Portugal, we examine spatio-temporal land cover patterns between 1990 and 2007 by integrating cross-matrix analysis, spatial metrics, and gradient analysis. Additionally, we overlay these land cover dynamics with municipal master plans that regulate land development in order to assess the compliance levels of this land-use regulatory system. Results indicate that: artificial areas are growing by coalescence and/or by scattered development along an urban–rural gradient; agricultural land is reducing and fragmentation is increasing to enlarge peri-urban spaces; there are high levels of conversion of agricultural land into urban land in protected areas, thus showing a lack of compliance to the land use regulatory system visible in the existing gaps between the original land-use assignments of the master plan and the actual developments.  相似文献

We discuss the implications of an alternative to the efficient market hypothesis (EMH) the adaptive market hypothesis (AMH). The AMH advances a theoretical basis for a new financial paradigm which can better model such phenomena as the recent financial crisis. The AMH regards the financial market order as evolving, tentative and defined by creative destruction in which trading strategies are introduced, mutate to survive, or face abandonment. The concept of investor rationality is less helpful than the distinction between investment strategies which are more or less well adapted to the prevailing market environment. We outline how a more systematic and grounded basis for behavioural finance can be developed in line with the latter approach. Based on this we develop testable hypotheses allowing the AMH to be distinguished from the EMH. Finally, we discuss how the AMH can aid our understanding of important issues in finance. A central insight is that in the survival of richest, as opposed to fittest, implied by the AMH there is much room for misallocation of resources as price and value uncouple. In this shifting financial market order the regulatory State features as a further market in which the vote market verifies or disrupts market conditions.  相似文献
