【摘要】 在分析城市吸引范围特点的基础上 ,指出了忽视实体属性的普通Voronoi图不能有效地表达城市吸引区空间网络。根据城市引力模型导出了城市吸引范围的边界曲线方程 ,探讨了曲边Voronoi多边形的自动生成方法。以MapInfo为平台 ,通过MapBasic编程计算并绘制了济南市的吸引范围。理论和实践表明 ,位置—属性一体化的曲边Voronoi图可以更好地刻划城市的空间吸引特征。更多还原

【Abstract】 Based on analyzing the characteristic of city’s attracting scope, the article points out that the ordinary Voronoi diagram neglecting object attribute cannot express effectively city’s spatial attracting network. According to the city gravitation model,the article deduces the curve equation of the boundary of the city’s attracting scope and studies the automatic forming method of the curving Voronoi polygon. Taking MapInfo as the platform, using MapBasic progamming, we calculate and draw the attracting scope of Jinan City. The theory and practice show that the curving Voronoi diagram that organically integrates the position with attribute can depict better the spatial attracting characteristic of cities.更多还原
