Study on urban construction planning based on karst landscape protection contributes to sustainable development of urban construction in karst area. Jinan is a city famous for karst spring water. Karst landscape plays a decisive role in urban construction. Through hydrogeological analysis, the distribution characteristics of karst mountain, cave, gully and flat dam in Jinan are analyzed. It is revealed that various karst landforms are involved in the spring circulation process to varying degrees. Some karst landforms have been destroyed in the process of urban construction and the karst landscape has been overexploited resulting in the direct or indirect weakening of spring water recharge and infiltration capacity and the decrease of spring water flow. Through the study of the principle of organic combination of karst landscape and urban construction planning, on the basis of protecting the ecological environment of the south, paying attention to the overall protection of the karst geomorphology system and the principle of accessibility of the karst landscape, the development countermeasures guided by urban planning are put forward based on karst landforms protection. On the basis of fully considering the special karst landform conditions in Jinan, the countermeasures are that the ecological control red line of urban construction planning should be set up based on karst mountains and valleys in southern of Jinan City. It is suggested that the bare carbonate rock continuous mountain foot line in the direct recharge area should be taken as the south control red line of urban development and included in the overall planning. The urban landscape is mainly displayed in the main axis based on karst mountains and springs, constructing East-West Axis-characteristic Landscape Belt along the Wufeng Mountain-Langmao Mountain-Hero Mountain-Qianfo Mountain-Long cave-Panlong cave-Jinping Mountain line and North-South Axis Landscape Belt along the Baotu Spring- Qianfo Mountain line, Baiquan-Panlong cave line, Baimai spring-Dajian Mountain line. Based on the karst river valleys and the river system, the urban spatial pattern is constructed, forming ecological corridor, restoring infiltration function of river. The form of urban construction should be shaped based on karst landform and the river system. The main form is semi-star like radiation type and the combination of central intensive type and zonal type. Based on the whole protection of karst geomorphology system and the scientific molding of karst landscape, the ecological landscape city with the symbiosis of spring and urban can be built. 相似文献

The Malaysian government has embarked on an ambitious refashioning of the nation called Vision 2020 in pursuit of its goal of becoming a ‘developed country’. A pivotal component of this ‘vision’ is the planning and provision of information technology (IT) infrastructure in a multi-billion dollar urban mega-project called the Multimedia Super Corridor (MSC). The purpose of my paper is twofold. First, I situate an official planning document for the MSC entitled Physical Design Guidelines for the Multimedia Super Corridor in the activity of transnational planning practice. Second, I argue that a thematic series of organizing planning concepts and practices can be identified in this document. These concepts and practices work in two ways: first, by representing highly positioned notions of sub-urban, middle-class urban design conventional in specific North American cities as universally applicable to, and desirable for, the broader national development goals the MSC is intended to lead; second, by creating a ‘total image’ for the MSC that suggests an apparently seamless relationship between the MSC and the proper citizens for it at every imaginable scale. One important effect of these plans is the material transformation of a rural landscape of and for production into an urban landscape of and for consumption. This transformation raises the question of who can belong to the ‘nation’ being (re)imagined via the MSC. 相似文献

城市景观格局的大气环境效应研究进展 总被引：10，自引：0，他引：10
城市规划不仅需要适应区域气候，更需要通过城市自身的合理空间配置来缓解因城市化引起的城市大气环境问题，因此，加强城市景观格局大气环境效应的研究对于提高城市规划的水平具有重要的意义。从城市下垫面的大气环境效应、大气数值模式、遥感应用技术以及城市规划的气候适应性等方面综述了城市景观格局的大气环境效应的研究进展，并分析了城市景观格局的大气环境效应应用于城市规划面临的主要问题。尽管城市景观组分的大气环境效应已经得到充分认识和应用，但是景观组分的空间组合，即城市景观格局对城市大气环境的影响及其应用研究仅仅处于起步的阶段。为了推动城市景观格局的大气环境效应研究并应用于城市规划之中，除了需要深入研究“格局影响过程”的机制外，还需要重点解决2个问题：一是寻找能够用来研究城市景观格局与大气环境相互作用的格局参数；二是确认具有一般意义的理想城市景观格局模式。 相似文献

The urban fringe, which can be seen as a special form of regional ecosystem with a spatial transition from urban to rural
areas, has strong heterogeneity and is a typical ecologically sensitive area. The expansion of cities and the landscape effect
of the changes have attracted wide attention. The primary aim of this study is to obtain an understanding of the spatial patterns
of landscape conversion and the corresponding environmental sustainability. With the help of GIS and Fragstats software, the
changes of landscape patterns before and after town planning were compared in An-Ding town of Beijing, of which the sustainability
was also revealed based on the ecological footprint using social and economic statistic data. The results showed that the
landscape pattern changed greatly during its conversion from several villages to a small town and the landscape fragmentation
increased due to road construction. Meanwhile, human disturbance increased with the constructed land extension. For the gap
between the ecological footprint and the biological capacity, An-Ding town ran an ecological deficit at that period, which
means it was unsustainable. However, the environmental sustainability decreased after planning due to the degraded green land
and forest. The results suggested that ecological management should be strengthened during the town planning period. 相似文献

Many cities in the twenty-first century are increasingly culturally diverse and neoliberal due to processes of political,
economic, and cultural globalization. While the need to examine the disjuncture between neoliberal ideology and practice remains
paramount (Brenner and Theodore in Antipode 34(3):349–379, 2002), the implications of neoliberal policy on the actual experiences and activities of diverse groups in the city require further
study (Hackworth in The neoliberal city: governance, ideology, and development in American urbanism, Cornell University Press,
Ithaca, 2007). This article contributes to urban studies engaging discourses about the practical rather than purely ideological aspects
of neoliberalism, and discourses about the experiences of racialization in North American cities. Through a case study of
social planning practices in contemporary Toronto, the author shows how neoliberal policies have shaped social planning in
Toronto since 1998, and how several cross-cultural organizations representing Chinese, continental-African, Latino-Hispanic
and South Asian communities were compelled to develop a collective to jointly contest the racialization of their communities.
The cross-cultural collective’s work forces a reconsideration of what constitutes mainstream Toronto and offers an alternative
approach to the dominant social planning in the city; however, it is not sufficient to replace the pervasive neoliberal hegemony
as long as it remains caught up within its structures. 相似文献

This paper suggests that the idea of “nature” remains a thematic leitmotif within interdisciplinary debates because it provides a potential bridge between the natural sciences, the social sciences and the humanities. Yet the development of new kinds of interdisciplinary insights into nature-society relations risks a renewed form of philosophical naturalism within which the epistemological tensions between bio-physical and social domains become blurred. In the fields of architecture, planning and urban studies, for example, we find instances where the idea of nature has mutated into a form of “neo-organicism” in which the ideological and historical context for contrasting ideas of nature remain obscured. If we re-examine our understanding of nature, however, drawing on recent insights in ecology, evolutionary biology and other scientific developments we uncover new possibilities for an interdisciplinary exchange of ideas that may avoid the crude determinisms of the past. 相似文献

This research examines urban sculpture production to understand how a public art (called “urban sculpture” in China) scene is produced in the country, using Shanghai as a case study. Theories of Chinese urban planning are innovatively applied. The findings generate theoretical implications for “contextualizing” public art production in geographical studies. All the chief officials in charge of urban sculpture planning in Shanghai were interviewed, and documentary analyses were conducted. The article argues that urban sculptures are conceived of as both symbolic capitals and didactic tools in the cultural policies of Shanghai. Urban sculpture planning plays an important role in coordinating and manipulating development of symbolic resources to advance urban entrepreneurialism within the ideological framework of the Communist Party’s leadership. The main features of the urban sculpture planning system of China are twofold: (1) The two-tier planning structure combines a master plan at the municipal level and detailed plans for site analysis and design guidance at the district level, all collaboratively working to create an attractive city image for urban entrepreneurialism. (2) An authoritarian style of planning system controls the contents and expression of urban sculpture within the ideological framework of urban sculpture planning. 相似文献

While the concept of urban agriculture investigates the way in which disused land within the consolidated city is returned to its citizens through a variety of farming practices, many pockets of rural land in peri-urban areas continue to be contested by institutions and communities – including informal farmers, formal farmers, municipal planners, metropolitan agencies, and investors – with contrasting interests. To date however, little scholarly attention has been paid to informal practices within the degraded areas of urban fringes and, more specifically, to the link between the expansion of peri-urban agriculture and the civic appropriation and negotiation of space in neglected peripheral areas. In this paper, we ask how a metropolitan sustainability fix is produced and contested both materially and discursively. We also explore how local residents involved in peri-urban agriculture claim the use of land for agricultural practices and in turn attempt to influence the urban agenda of the neoliberal city. Inquiring how competing visions of nature act as obstacles in this negotiation process, our analysis of the peri-urban Baix Llobregat Agricultural Park in Barcelona reveals that the imposition of official visions about how needs for food and agriculture should be fulfilled, which landscapes are esthetically acceptable, what nature is, and how land should be controlled and developed indicate why apparently “marginal” and informal urban agriculture in the periphery has come to be subordinated to the planning of the neoliberal city and of a metropolitan sustainability fix – a partial sustainability fix that is however progressively being questioned and renegotiated. 相似文献

The growing field of urban political ecology (UPE) has greatly advanced understandings of the socio-ecological transformations through which urban economies and environments are produced. However, this field has thus far failed to fully consider subjective (and subject-forming) dimensions of urban environmental struggle. I argue that this can be overcome through bringing urban political ecology into conversation with both post-structural political ecology and critical geopolitics. Bridging these literatures focuses attention on practices of socio-ecological exclusion and attachment through which environmental subjectivities are formed. This argument is drawn out through a case study of the politics of local economic development and conservation within the watershed of the Big Darby Creek near Columbus, Ohio. This struggle was driven by a preservationist movement that coalesced around a shared understanding of socio-ecological hybridity as a source of metaphysical insecurity. Hybridity appears here as a site of political and ethical struggle over social and ecological exclusions produced in the pursuit of security. This case study demonstrates a paradox of environmental politics: the non-human is at once a site of constituent possibilities for identity and subjectivity as well as forces which seek to foreclose this radical openness. Recognizing the paradoxical nature of environmental struggle allows for a more complex and nuanced account of the multifarious forces that shape the formation of environmental subjectivities. 相似文献

Due to growing social and physical transformations, contemporary cities reveal the profound necessity of proper scientific approaches that are adjusted to conditions of global complexity and dynamic patterns of development. Predominance of an overall market economy, sporadic deregulations of administrative powers and a lack of local investment or resources, dominate urban reality. Incongruous urban decision-making procedures result in contextually inappropriate and incoherent urban management. We will explore these operational elements in Savamala neighbourhood in Belgrade. The actor-network theory (ANT) is applied to analyse the hyper dynamic circumstances of transition in Serbia. An unclear regulatory framework, powerful financial means for investment and limited institutional influence of citizen participation, deploy unstable urban development modalities at the neighbourhood level. ANT offers an insight into how urban norms, projections and structures unfold and how associations and translations of urban elements develop. Plausible yet complex collisions in Savamala constitute a challenge for ANT in mapping urban development processes and visualizing actors and networks through diagrams. Based on the presented results, the illustrative perspective of ANT minimalizes both the importance and the influence of the permanence of urban structures across time and space. Instead, ANT deals with a city as a contingent, fragmentary and heterogeneous, yet persistent product of actors, their roles, associations, agencies and networks. Possible adaptations of ANT should respond to the needs of non-scientific actors and practitioners for an interpretive tool that addresses undercover processes and mechanisms or provides explanations, recommendations or operational diagnoses on how to absorb urban development dynamics. 相似文献

Residential relocation under market-oriented redevelopment: the process and outcomes in urban China 总被引：3，自引：0，他引：3
Fulong Wu 《Geoforum》2004,35(4):453-470
Residential displacement by urban regeneration in western economies and forced relocation in the Third World countries are contentious issues. This paper, based on a household survey in Shanghai, examines the process and outcomes of residential relocation under market-oriented urban redevelopment in China. The results show that commodification of the socialist tenancy right helped to initiate large-scale urban redevelopment. First, there has been a complicated process of negotiation during residential relocation, involving residents, development companies, and government agencies. The de facto right of public housing tenants is considered by a pragmatic attitude in urban redevelopment in the early years. Second, residential relocation is accompanied by the changes in housing tenure, housing conditions, and the improved built form of planned residential districts. Nevertheless, the social conflict has become intensified recently because the deepening of commodification began to favour property developers by constraining the compensation standard for relocated households. 相似文献

If we had to point out one single feature to define Brazilian cities today, it would be the existence of a dual built environment: a landscape produced by private entrepreneurs and contained within the framework of detailed urban legislation, and another one, three times greater, self-produced by the poor and eternally situated in an intermediate zone between the legal and the illegal. In addition to being an expression of economic and social disparities, this contrast has profound implications on the form and functioning of the cities. The sprawl of the precarious peripheries has lead to an absurd disconnection of poorly urbanized spaces and the city center where jobs, cultural and economic opportunities are concentrated. The effects of this persistent territorial exclusion are devastating and occur in both the peripheries and the city center. The purpose of this paper is to explore the nexus between the precarious and risky urbanization which took place in Brazilian cities and the urban violence that seems to be the most recent and visible face of this model, using the concrete example of different cities in the state of São Paulo. In order to construct the links it is first important to understand how patterns of economic development and population trends have contributed to the generation of risk urbanization and how planning and urban management policies interact with it. 相似文献

Gated communities and urban fragmentation in Latin America: the Brazilian experience 总被引：3，自引：0，他引：3
Martin Coy 《GeoJournal》2006,66(1-2):121-132
Since the mid-1970s, gated housing areas of the privileged have been spreading in Latin American cities. They have to be seen
as a visible consequence of the deepening social disparities within Latin American societies and the resulting fragmentation
of urban space. Condomínios fechados (Brazil) or barrios cerrados (Argentina) can be typified following different criteria, such as formation, location, size, fittings, construction typology,
as well as social structure. Three groups of actors influence the process of their expansion: the real estate companies, for
which the new form of living offers an attractive market segment, the target groups, whose increasing expectations regarding
security and living comfort need to be met, and the public authorities, who have to find adequate responses concerning the
further orientation of urban development. Based on case studies from Brazil, the paper will discuss the different phases of
gated community expansion and the reasons why this is happening. Their internal structure and differentiation, as well as
consequences for socio-spatial development and urban planning will also be dealt with. 相似文献
