The simulation of land use change is important in environmental impact assessment and land use planning. We assessed the land use scenarios of China in the next 100 years based on the SMLC (surface modelling of land cover change) model and Dyna-CLUE (dynamic conversion of land use and its effects) model. Three SRES scenarios were evaluated: Global Economy (A1FI): lean government, strong globalization; Continental Markets (A2a): lean government, regional culture and economic development; Regional communities (B2a): much government intervention, regional cultural and economic development. Ten land cover types were simulated, which are cultivated land, woodland, grassland, built-up land, water area, wetland, nival area, desert, bare rock and desertification land. The SMLC model was used to calculate changes in area for each land use types in the future at country level while the spatially explicit land use model Dyna-CLUE was used to simulate land use pattern at 2 km2 resolution based on the country level areas demands for each land cover type. The results show that the cultivated land would decrease in all of the three scenarios, while in the A2a scenario, the cultivated land would decrease with the lowest rate because of the high population growth, high level of market protection and low agricultural efficiency; in the B2a scenario, it would decrease with the highest rate caused by the decreased population numbers and increased crop productivity. The nival area would decrease with the highest rate in the A1FI

[ScienceDirect, via Biblio-SHS] Auteur : Zhang Xianchun, Shan Zhuoran Paru dans : Energy Procedia Volume 16, Part A, 2012, Pages 353-358 2012 International Conference on Future Energy, Environment, and Materials Abstract The urbanization level of china will exceed fifty percent in 2011. At the present stage, the urban-rural dual structure is more and more prominent. Due to the urban-rural dual management,many problems were found in the joint of urban and rural in the process of urbanization. This article summarizes the related achievements of land-use and management of Chinese joint of urban and rural for the last two decades. It introduces case-study in three aspects of cognitive, methodology and space planning, and discourses the achievements of different land-use types in the points of construction land, non-construction land.At the same time, this article elaborates the researches in landmanagement and points out the current excellent processes and the main problems.Finally, this article proposes the anticipation and prospect of study in the future.

We mapped urban land from satellite images by using a hybrid approach of spectral mixture analysis, unsupervised classification, and expert rules. We employed binary logistic regression to model the probability of urban land conversion as a function of spatial independent variables. In recent years Hangzhou started its transformation from a compact, monocentric city to a polycentric city. We found that accessibility to the central business district, industrial centers, roads, Qiantang River, the amount of built-up area in the neighborhood, locations of markets, and spatial policies were the major determinants of Hangzhou's urban land conversion. Moreover, the availability of land in the neighborhood has become increasingly important in recent years. We identified several major institutional forces underlying Hangzhou's urban development: administrative annexation and development zones, the increasingly important role of the market, and the unique role of local government. The results from our research indicate the need for policies and plans that can better manage and reduce urban sprawl in Hangzhou. [ABSTRACT FROM AUTHOR]

Published in: Cross-Cultural Communication Vol. 8, No. 4, 2012, pp. 34-38 Abstract This paper aims at evaluating implementation performance of land use planning of Chengdu city from economy, efficiency, effectiveness and equity perspectives. The results shows that that over the period of 1997-2006, the land use planning of Chengdu city achieves a better implementation performance in economy, efficiency and effectiveness fields but in the equity fields is not so good. Then the paper proposes some policy recommendations to improve the land use planning.

[ScienceDirect, via Biblio-SHS] Auteur : Steffen Lehmann Paru dans : Habitat International, Available online 4 January 2012 Abstract The purpose of this paper is to explore the rapid urbanization of Chinese cities with a focus on the plans for a new, ongoing urban sub-centre in the north-west of Shanghai: Zhenru Urban Sub-Centre. Information-rich urbanization is a defining feature of the 21st century, reshaping cities and communities in China and in developing countries around the world. The scale and pace of change requires a solid systems approach of urban development. In 2011, China announced that it has reached an urbanization rate of 50%. If we take rapid urbanization as a given and that it is already well underway, it is still widely unclear what research needs to be conducted and policy changes made to support municipalities of fast transforming cities and to avoid repeating the development mistakes that have occurred in industrialized nations, i.e. driving urban growth with high consumption patterns without fully considering the environmental and social needs and occupants' behaviour and aspirations. This paper compares two cases of urban development patterns for new sub-centres for polycentric city structures: It relates to new urban sub-centres in Berlin (Germany) and Shanghai (China), and the relationship of these sub-centres to 'Network City' theory. Network theory is useful in this context as the 'network' metaphor and concepts of decentralization seem to have replaced the 'machine' metaphor which was based on efficiency based on the availability of cheap fossil fuels. As cities aim to move towards more resilient urban ecosystems and polycentric systems, the case of Potsdamer Platz Berlin, compared to Zhenru Sub-Centre in Shanghai, is discussed. Both are transport-oriented developments promoting mixed-use density and less car-dependency. According to documentation of the Shanghai municipality, Zhenru urban centre, which is cur

Xuefei Ren's work on the high-end of the building boom in China brings together the sociology of globalization with the study of architecture and the built environment. Building Globalization treats architectural production as crucial to the material and symbolic ways in which global cities are made. Based on Ren's doctoral research at the University of Chicago, the book draws on fieldwork conducted in Beijing and Shanghai between 2004 and 2008, covering the bull years leading up to the Beijing Olympics. China is now taken to exemplify the geo-demographic shift that has seen developing countries lead current processes of urbanisation. However the Chinese government's attitude towards quanqiuhua chengshi (global cities) and its support for rapid urban growth from the mid-late 1990s represented a striking reversal of official policy which had been to limit the growth of large cities and promote instead the development of small-medium centres (p.11). The re-scaling of state power to metropolitan level in the interests of enhancing urban competitiveness has been an international trend in recent decades. In China this has proved particularly effective in driving urban growth, given state ownership of land and government control over household registration, urban planning and development decisions. Metropolitan governments in China have the kind of ownership and discretionary powers of which the most boosterist western city mayors can only dream. Ren argues convincingly that the processes shaping these cities are increasingly transnational; in particular, the forces that make buildings 'operate beyond national boundaries, as seen in the circulation of investment capital, the movements of built-environment professionals, and the diffusion of new technologies' (p.6). However, while Chinese economic growth may have destabilized a global balance of power dominated by the triad of the USA, the European Union and Japan, Ren's analysis suggests that older core-peripher

Abstract We performed a bibliometric analysis of published urbanization research from 1991 to 2009, based on SCI and SSCI database. Our analysis reveals scientific outputs, subject categories and major journals, international collaboration and geographic distribution, and temporal trends in keywords usage in urbanization studies and discusses the relationships between urbanization papers and urbanization rate and offer a substitute demonstration of research advancements, which may be considered as a potential guide for future research. The growth of article outputs has exploded since 1991, along with an increasing collaboration index, references and citations. Environmental sciences, ecology, environmental studies, geography and urban studies were most frequently used subject categories and Landscape and Urban Planning was the most productive journal in urbanization studies. The United States was the largest contributor in global urbanization research, as the USA produced the most independent and collaborative papers. The geographic distribution of urbanization articles overlapped quite well with regions with high economic growth in North America, Europe, and Pacific-Asia. A keywords analysis found the USA and China were "hotspots", confirmed land-use's significant position and revealed keen interest in ecological and environmental issues in urbanization studies. In general, urbanization research was strongly correlated with the urbanization rate although there were different patterns and underlying processes across different countries. This is the first study to quantify global research trends in urbanization. Our study reveals patterns in scientific outputs and academic collaborations and serves as an alternative way of revealing global research trends in urbanization.

Development zones are the important carriers of China's promoting industrialization and attracting international investment in the past 30 years and act as the primary means of city expansion. In this article, we analyse the low efficiency of land use problem existing in China's current development zones. Comparing with the general old city update phenomenon, we make a detailed illustration on the feasibility and comparative advantage of redevelopment of development zones. On this basis, combining with the investigation practice, we propose the basic redevelopment models of development zones and analyse the typical redevelopment cases of development zones in Xi'an, Shanghai, Changzhou, Hangzhou and Nanjing.

The influence of regional culture and values on Chinese urban residential choice has been steadily increasing, but unconsciously. Indeed, recent scholars have studied a variety of phenomena that imply a certain shift- away from classical explanations of urban residential choice and real estate patterns. This has led to the coining of some new terms and concepts, such as "Xuequ House", "Mortgage Slave", "Woju" and "Ant Tribe". This tendency towards the study of culture and values is directly related to the Theory of Scenes from the Chicago School of Sociology. In this paper, we apply the Theory of Scenes to Chinese urban residential choice research. First, we review the relevant theories and Chinese urban history, especially the changes after 1949, and present three hypotheses. Then, based on the Scenes theory, we construct a cultural framework to study 375 countries of 35 first-tier cities of China. Aiming at Chinese urban inhabitants from twelve different age groups, we use the Stepwise Regress model to do the statistical analysis. In doing so, we prove our assumptions regarding the importance of regional culture and value. Based on these conclusions, we proceed to give some relevant policy suggestions to the Ministry of Housing and Urban-Rural Development of the People's Republic of China and the local Municipal Bureau of Planning and Land Resources.
