Analysis Of Influence Scope Of Urban Space Based On Voronoi Map

Inter-city region space scope is regional influence a city’s visual performance in space by analyzing the space between the scope of urban areas can be drawn from the space between the urban areas of the state of interaction, the study of urban areas, urban and rural great value coordinated development of urban and rural industries and public service facilities layout. By selecting urban areas reflects the influence of nine indicators, obtained by principal component analysis regional influence Lanzhou City eight counties score as the influence of the weight of Lanzhou City, the county district,and then weighted Voronoi diagram Vector Generation improved algorithm based on the final results of the arc generation algorithm based on weighted Voronoi diagram, and then use the algorithm affected coverage Lanzhou county area to be divided, it has been portrayed in Lanzhou spatial scope of weighted Voronoi FIG. Finally, on the Lanzhou Lanzhou Yearbook weighted Voronoi diagrams and data analysis, the development of Lanzhou put forward constructive suggestions.
