Forecasting the future electric demand and its geographical distribution is a prerequisite to generate expansion-planning scenarios. The load growth pattern is related with the urban structure and its land-use. The model for simulating urban structures must be explicitly dynamic and must contains mechanisms for linking its macrostructure to micro behaviours. The paper presents a methodology, wh...

Urban sprawl is a hot topic of global concern with increasing dramatically and impact on ecological environment. But there is not a mature method to explain the detail of process of urban sprawl and dynamic changes. In this paper, the dynamic changes of urban is studied based on 1980, 1988, 1994, 2000 and 2005 five remote sensing images of Shenzhen. It is distinguished three types including inf...

Nowadays there is a high rate of urban expansion which can not be ignored in proper urban management. Parallel to the urban expansion we are faced with an increase in urban problems, which will lead to complexities dealing with the urban management and planning processes. A city is a set of condensed and broad functionalities which requires handling of huge amount and diverse types of geospatia...

Electronic cities result from the implication of information and communication technology (ICT) in the contemporary era. Significant ICT development and internet network expansion as well as the need of urban management to new ideas in managing cities lead us toward a new strategy called "electronic cities". The current study aims at investigating the Electronic Cities' Strategic Plan...

China's extensive urbanization has resulted in a massive loss of natural habitat, which is threatening the nation's biodiversity and socioeconomic sustainability. A timely and accurate understanding of natural habitat loss caused by urban expansion will allow more informed and effective measures to be taken for the conservation of biodiversity. However, the impact of urban expansion on natural ...

This paper presents an agent-based urban land market model. We first replace the centralized price determination mechanism of the monocentric urban market model with a series of bilateral trades distributed in space and time. We then run the model for agents with heterogeneous preferences for location. Model output is analyzed using a series of macro-scale economic and landscape pattern measure...

A Cellular Automata model based on Partial Least Squares Approaches is proposed for simulating complex urban systems. The core part of Geo-CA model is the transition rules and a mass of independent spatial variables are involved in the process of creating CA model. Studies have focused on eliminating correlation using Multi-Criteria Evaluation (MCE) and Principal Component Analysis (PCA), but t...

Because of the lack of time-series spatial data on urban components, urban expansion in developing countries has usually been studied using a pixel-based approach, despite the coarse spatial resolution associated with this technique. To understand the residential-scale processes involved in urban expansion, we developed feature-oriented GIS data extracted from very high spatial resolution satel...

Accelerating urbanization has been viewed as an important instrument for economic development and reducing regional income disparity in some developing countries, including China. Recent studies (Bloom et al. 2008) indicate that demographic urbanization level has no causal effect on economic growth. However, due to the varying and changing definition of urban population, the use of demographic ...
