用MapInfo数字化了西畴县兴街镇地图,用Voronoi图替代各村之间的边界,以人口密度为例,制作了兴街镇人口密度格网地图,显示该镇人口分布具有趋向于畴阳河谷及交通干线分布的趋势;计算了以兴街镇为中心的村镇体系的聚集分维,显示兴街镇中心性作用较强;最后得出Voronoi图和聚集分形是该镇统筹城乡发展的空间优化措施.
用MapInfo數字化瞭西疇縣興街鎮地圖,用Voronoi圖替代各村之間的邊界,以人口密度為例,製作瞭興街鎮人口密度格網地圖,顯示該鎮人口分佈具有趨嚮于疇暘河穀及交通榦線分佈的趨勢;計算瞭以興街鎮為中心的村鎮體繫的聚集分維,顯示興街鎮中心性作用較彊;最後得齣Voronoi圖和聚集分形是該鎮統籌城鄉髮展的空間優化措施.

The paper makes a grid map of the population density by using Mapinfo digital scanned map of Xingjie town of Xichou County, using Voronoi diagram as the village boundary and using population density as example, showing the population tends to distribute along Chouyang Rive and major roads, calculates the random aggregation dimension of the town-village systems in Xingjie, with the result showing Xingdie town plays a central role and concludes that Voronoi diagram and the aggregation fractal will no doubt provide the most optimized spatial structure for the plan and development of the town and rural settlements as a whole in Xingjie or other regions.
