The Study of Hyper-graph Urban Spatio-temporal Expansion Model Based on Features

For the sake of realizing the demand of dynamic analysis of change of urban patio-temporal expansion, forecasting of expansion trend and the development of urban patio-temporal expansion model, this paper carry through from four aspects: detailed analyzed the mechanism and rule of change of urban patio-temporal expansion, abstracted important factors that affect urban spatio-temporal expansion features, assigned appropriate weight value to these factors and constructed their relations, then adopted hyper-graph theory to express and describe these factors and their relations, and ultimately constructed hyper-graph urban patio-temporal expansion model based on features. The case study taking statistic data of Beijing city from 1984 to 2005 as study base, the experimental result shows that this model has better reference value in urban expansion of study and forecasting, and provides effective reference basis for administrative department, also provides useful reference for other cities.
