An understanding of the dynamic process of urban growth is a prerequisite to the prediction of land-cover change and the support of urban development planning and sustainable growth management. The spatial and temporal complexity inherent in urban growth requires the development of a new simulation approach, which should be process-oriented and have a(More)
The rapid urbanisation and urban sprawl in particular in the developing world require a scientific understanding of complex urban growth patterns and processes. This knowledge is highly crucial to sustainable land management and urban development planning. Progress in modern remote sensing and GIS techniques has opened up great opportunities, and(More)
BACKGROUND The inequities in healthcare services between regions, urban and rural, age groups and diverse income groups have been growing rapidly in China. Equal access to basic medical and healthcare services has been recognized as "a basic right of the people" by Chinese government. Spatial accessibility to healthcare facilities has received huge(More)
China has achieved rapid urbanization and unprecedented economic booming over the past three decades. Numerous cities and towns dreamed of cloning the miracles of Shenzhen and Pudong, Shanghai, in terms of their international development. However, inappropriate development strategies have meant that the majority of fast expanding urban suburbs or newly(More)
Involving stakeholders in decision-making at planning workshops requires a computer system to respond quickly to various scenarios proposed by participants. Due to the increasing complexity of urban systems, such planning support often faces the challenges of "big data" and poor computational performance. This paper proposes a new approach using parallel(More)
Modeling thermal comfort provides quantitative evidence and parameters for effective and efficient urban planning, design, and building construction particularly in a dense and narrow inner city, which has become one of many concerns for sustainable urban development. This paper aims to develop geometric and mathematical models of wind and thermal comfort(More)
A city is a complex system with complicated interactions between transport, land use, environment, population at a variety of scales. Understanding these interactions is the prerequisite for predicting urban changes, supporting sustainable urban development planning. In this paper, we divide the evolution of urban data into four stages. Then the(More)
