Research Review on Urban Land Sprawl in China
CHU Pei-pei et al (School of Land Sciences and Technology,China University of Geosciences,Beijing 100083)
Through the index and analysis of relevant literatures,the research progress at home and abroad on urban land sprawl in China were systematically evaluated. As a whole,the evaluation results showed that the research objectives were mainly aimed at the large cities and eastern ones in China,insufficiently at small-medium cities and western cities. The research fields were mainly focused on the characteristics and driving forces of urban space sprawl,insufficiently on its process and mechanism. And that the research methods were to adopt RS and GIS technologies to establish CA model and SLEUTH model to simulate urban sprawl. Currently,economic development and population expansion are the two main driving forces for urban sprawl. But due to the differences of regional characteristics and urban development trends,the driving forces and urban development characteristics are also different. On that basis,the future research orientations were prospected to provide methodological and theoretical references for future research on urban land sprawl.
