The shift to market forces in Poland, East Germany and Czech Republic has fundamentally reconfigured its economic geography. In particular, spatial inequalities between neighboring Polish, Czech and German border regions have re-emerged forcefully in response to new values, expectations and preferences. In this paper the example of coal mines illustrates the potency of spatial planning. The abundance of coal mines in the Polish, Czech and German borderland at or near abandonment and their proximity to ecological corridors make them candidates for renewed uses in industry or conservation. Attention will also be given to the main environmental problems caused by wrongly conducted spatial policy on this borderland. Transforming a landscape requires continuation of guidance and financial assistance of the European Union. 相似文献

Regional inequalities in economic development in Spain are widely recognised, but similar patterns of levels of living have been less studied. Some of the general factors which might contribute to regional inequalities are discussed. Although it is difficult to identify their precise role, it is argued that the pattern of economic growth, the character of regional economic structures, population distribution and urbanisation, return migration, and the nature of Spanish regional and local government all contribute in varying ways to inequalities in levels of living in different regions. Furthermore, they suggest that such inequalities have persisted throughout the 1970's. The regional patterns are then described and trends of change between 1970 and 1981 examined. The evidence suggests that the decade saw a widening dichotomy in levels of living in Spain with the south and west showing deterioration and the N and E showing relative improvement. 相似文献

In the recent decades southern European cities experienced morphological changes and a demographic transition towards zero (or negative) growth and aging. Population dynamics shifted from the impressive growth of the post-industrial period into recent de-concentration processes determining the spillover of commercial and residential settlements across the surrounding rural areas. Based on long-term demographic data, the present study hypothesizes that urban expansion did not follow a one-way linear path from compactness to dispersion while reflecting differentiated growth patterns based on the specific socioeconomic context at the local scale. Along a sufficiently long time period non-linear expansion waves alternating settlement densification and scattering are expected to be found especially in complex urban contexts such as those developed in the Mediterranean region. This hypothesis was tested for a paradigmatic case study in southern Europe (Athens, Greece) using demographic data covering 160 years (1848–2011). Urban growth in Athens was assessed through the analysis of long-term census data made available on a district level. These data provide information on the spatial distribution of resident population and characterize distinct expansion waves according to the dominant socioeconomic context. Results of the study were discussed in the light of the debate on future development of the Mediterranean cities and the (changing) economic relations with the surrounding region. 相似文献

The essay portrays urban development in Germany at the end of the 20th century in the transition from Industrial Modernity to the New Modernity. The city of the Industrial Modernity is described as a traditionally closed and mixed city. It corresponds to the classical European model of the compact city with a clearly defined centre and a surrounding area which is unambiguously oriented towards this centre. This urban model is disintegrating in Germany. The essay explains this lingering but fundamental process of change. The inner cities are decreasing in importance in favour of the urban fringe, traditional relationships and connections with our cities are lost, new regional activity areas are emerging in the environs of cities. Although the urban impacts of new communication technologies have not been completely clarified, they are changing previous local relationships in the cities. This is not without consequences for urban neighbourhood relationships. The increasing polarisation in German society also affects urban structure. The social mixture in cities disappears on a small scale, public spaces are losing their functions, undesirable population groups are excluded from participation in urban life in new shopping, leisure and transport facilities. The interaction between private and public agents who influence and determine urban development has changed in recent years, and the civic sense of responsibility for the city must be newly defined. Hopes are put into the debates on the Local Agenda and - in spite of its dangers - into a project-oriented planning approach. 相似文献

The central focus of this paper is on the differentiation of basic urban trading services in middle income cities and its role in service provision for the poor. Most studies dedicated to service delivery to the poor emphasize the inequalities pertaining from a growing differentiation in provision and take up some of the arguments of the splintering urbanism thesis. The paper examines some of the main claims made in this debate through a case study of Cape Town (South Africa). It illustrates how differentiation is implemented through service levels and tariffs and suggests that it is a pragmatic way of accommodating social and spatial disparities in a highly polarized city, while making progressive steps in favour of the poor. The main argument is that, in Cape Town like in many middle income cities, urban diversity restricts the relevance of conventional social policies and the scope of local solidarity with regard to service delivery. The differentiation of provision is thus a strategy to bring the diversity within the public service, and hence to preserve an institutional and financial public capacity of delivering subsidized services to the poor. 相似文献

Although Germany is not among the most hazard-prone regions of the world, it does experience various natural hazards that have caused considerable economic and human losses in the past. Moreover, risk due to natural hazards is expected to increase in several regions of Germany if efficient risk management is not able to accommodate global changes. The most important natural hazards, in terms of past human and economic damage they caused, are storms, floods, extreme temperatures and earthquakes. They all show a pronounced spatial and temporal variability. In the present article, a review of these natural hazards, associated risks and their management in Germany is provided. This review reveals that event and risk analyses, as well as risk management, predominantly focus on one single hazard, generally not considering the cascading and conjoint effects in a full multi-hazard and risks approach. However, risk management would need integrated multi-risk analyses to identify, understand, quantify and compare different natural hazards and their impacts, as well as their interactions. 相似文献

One of the major means to foster European integration is the establishment of border spanning regions (‘Euroregions’). This
is particularly important on the Eastern borders of the EU, e.g. in Eastern Germany. There, however, a double transformation
to post-socialist society is taking place, both inside and outside the EU. Tensions arise between objectives on local and
higher political levels, intensified by totally different economic structures and access to EU funds on both sides of the
border. This is particularly true for the case of the emerging Euroregion Viadrina. Problems in preserving old industrialised
localities in East Germany (e.g. steel) and attempts to resurrect the urban fair place Frankfurt/Oder, clash with transition
in agriculture and consumer industries and with new concepts in tourism development and environmental protection in the Polish
border zone. In region building, political, economic and ideological goals compete with each other. Local initiatives and
higher political governance may both support and hamper each other. The same holds true for the interdependence of cultural
integration and economic development. The paper concludes that regional economic development can only be expected if, via
the building of the Euroregion, the interplay of these factors leads to compromise and harmonization between the different
parties involved.

The author examines the recent situation in the development of cities in Russia. Recent trends include a lack of growth and even a decrease in population; extensive economic restructuring; a grave ecological situation in cities; and recent peculiarities in the geopolitical situation and population migration. Due to the new economic, demographic, geopolitical and social situation in Russia it is necessary to re-evaluate the prospects for the development and growth of the big cities in this country. The system of basic documents for regional and city planning in the former USSR and in Russia includes different stages: from The General Scheme for the Settlement Systems of the Country and The Regional Territorial Complex Schemes of Environmental Protection in different regions to the detailed plans for the different parts of cities and towns. The shortcomings of this system and in the process of the realization of the schemes of regional planning and general plans for cities are documented. 相似文献

The concept of environmental justice (EJ) has recently gained currency, both as a factor for and a goal of sustainable development. Its implementation in practice implies establishing current environmental injustice patterns and analysing planning policies, with the aim to reduce socio-demographic inequalities in the negative environmental impact borne by different population groups. This paper proposes a method to assess differential exposure to excessive pollution levels by socio-demographic groups in intra-urban spaces.The approach developed in this paper is based upon GIS and quantitative spatial analysis techniques. It incorporates the idea of an ‘environmental justice weighting scale’ for policy-making, using normative pollution thresholds to measure inequalities more objectively and consistently. Spain’s two largest cities, Madrid and Barcelona, have been chosen as case-studies, taking nitrogen dioxide as the pollutant, and the geographic distribution of six vulnerable population groups (children, elderly people and international immigrants) in the year 2010. The results reveal that a large part of these groups suffer exposure to air pollution exceeding the maximum permitted levels disproportionately, which would imply a case of environmental injustice. 相似文献

Recent policy initiatives for the inner cities and regions of Britain were reviewed in the context of the continued and deepening processes of metropolitan decentralisation of population and economic activity and of regional divergence in levels of economic well-being. The result is a policy focus on those areas considered as being on the margins of economic viability. Research evaluating past policy indicates only modest potential for the success of such a focus. Policies having a growth stimulation objective may be better centred outside these most marginal areas. Policies having a welfare objective may achieve greater efficiency if they have no particular spatial dimension. 相似文献

The dramatic political and economic changes in Europe, Asia, and the Middle East during the early 1990s have had a dramatic impact on international tourism. Between 1974 and 1990 there have been significant shifts in international tourist originations. The purpose of this paper is to describe and analyze the changing patterns and to compare the two time periods. A key component of the study is the construction of a Population-Adjusted Travel Index which assesses the capability of a country to generate tourists relative to population characteristics. Findings indicate that Europe is still the leader in trips generated, even though the proportion from this region is declining over time. Asian countries exhibited the most marked improvement due primarily to the tremendous economic expansion taking place on the Pacific Rim. In contrast countries of the Middle East have declined in importance relative to international tourism. This is due to political and economic instability in the region. 相似文献

The retail system is continuously adapting itself to changing demographic conditions, consumer behavior and economic conditions.
Existing retail units, getting larger in order to achieve economics of scale, and new forms of large-scale retailing do not
fit easily in the traditional spatial pattern of retail concentrations. Neverteless the spatial distribution of retailing
in urban areas, as schematized by Berry thirty-five years ago, still has its value. Through an upward hierarchical movement
the retail system has adapted itself to an inflexible spatial system, in which downtown has still a dominant position. Future
developments, however, may weaken the position of central shopping areas in favour of peripheral locations.

Exploring the characteristics of major natural disasters in China and their impacts during the past decades 总被引：4，自引：3，他引：1
The exploration of the characteristics of natural disasters (NDs) and their impacts have important implications for guiding disaster prevention and mitigation. This paper discussed the characteristics of the major NDs that occurred in mainland China between 1980 and 2011 based on the number of disasters and fatalities, the affected population, and the resulting economic damages. We further examined the relationships between the level of social/economic development and the disaster losses. At last, we also explored the trend variations in disaster losses and losses expressed as a percentage of gross domestic product (losses/GDP) for 31 provinces in China over the period from 1990 to 2011. The results show that over the past three decades, the number of major NDs and the number of affected population appear to exhibit a detectable increasing trend, while the direct economic losses and the deaths show a slight increase trend. The correlations between the number of disasters and the economic losses as well as deaths and between the economic losses and socioeconomic status were not significant (p > 0.05), which indicates that the growth in the number of disasters do not result in a significant increase in the disaster losses. Further investigations demonstrate that as economies develop, there are fewer losses/GDP in China over the past two decades. The per capita accumulative losses and losses/GDP in the western and central regions were higher than that in the eastern parts of China. There are significant regional differences in the trends in disaster losses and losses/GDP in China. Statistics also indicate that more than 70 % provinces in underdeveloped regions show an increasing trend in disaster losses, whereas exceeding 90 % provinces exhibit a decreasing trend in their losses/GDP. These results suggest that the economic development may have played an important role in improving the capacity of disaster prevention and reduction. 相似文献

Understanding the nature of spatial economic change in China's most rapidly developing regions requires a conceptual and methodological
shift away from the conventional macro-perspectives. An analysis of the processes and mechanisms which underlie the unique
patterns of transformation in China's lower Yangzi delta is undertaken. The paper focuses on the emergence of small scale
institutional and transactional activities as they relate to the location of nonagricultural enterprises in the countryside.
The way in which networks of interactions and interrelationships are embedded within specific local exigencies and opportunities
for development reveals much about the wider regional spatial economic patterns and trends. The historical, administrative,
and territorial contexts and some detailed examples of the resulting institutional frameworks are also highlighted. The paper
proposes a framework whereby spatial economic transformation in China is reconceptualized in relation to intensely localized
place-based institutional structures.

In this paper a methodology for a multi-risk assessment of an urban area is introduced and performed for the city of Cologne,
Germany, considering the natural hazards windstorm, flooding and earthquake. Moreover, sources of the uncertainty in the analysis
and future needs for research are identified. For each peril the following analyses were undertaken: hazard assessment, vulnerability
assessment and estimation of losses. To compare the three hazard types on a consistent basis, a common economic assessment
of exposed assets was developed. This was used to calculate direct economic losses to buildings and their contents. The perils
were compared by risk curves showing the exceedence probability of the estimated losses. In Cologne, most of the losses that
occur frequently are due to floods and windstorms. For lower return periods (10–200 years) the risk is dominated by floods.
For return periods of more than 200 years the highest damage is caused by earthquakes. 相似文献

Explaining divided cities in China 总被引：1，自引：0，他引：1
Explanations of the existence of socio-spatial divisions in Western Europe and the United States revolve around the importance of economic, demographic, political, and socio-cultural macro developments and often also on the role of globalization. Much of the literature also emphasizes the role of institutions, especially the national and local state as well as individual and household constraints and opportunities. Many authors explain socio-spatial divisions by a mix of these factors and developments. This paper provides an account of the current state of affairs concerning the literature and theory on divided cities in China. Concentrating on a selection of 88 articles published in international journals during the last decade, we examine how authors explain urban socio-spatial divisions in Chinese cities. The paper indicates that a five-category framework of trends, policies, players, position, and preferences are useful in addressing the complexity of explanations attributed to current urban divisions and inequalities in Chinese cities. While the spatial patterns in the Western and Chinese contexts share rather similar characteristics, the interplay of mechanisms is significantly different. The influence of the state, its institutions, and the cultural background has a much stronger explanatory power in China than in the West. 相似文献
