一种用于界定经济客体空间影响范围的方法——Voronoi图

A new approach to delimitate influenced coverage of an economic ojbect——Voronoi diagram

经济客体的空间影响范围界定十分复杂 ,但在区域规划和城市规划中有着重要的理论和实际意义。该文提出可采用 Voronoi图方法用于经济客体的空间影响范围界定 ,介绍了 Voronoi图的基本原理和其若干扩展 ,编写了生成 Voronoi图的程序 ,最后以城市为例探讨了 Voronoi图在经济客体空间影响范围界定中的应用。

Delimitating economic object's affacted coverage is very difficult, but it is very important to urban planning and regional planning. In practice, we often define the administrative division or geographical unit of an economic object as its influential area, and this has its deficiency. This paper presents a new promising method which uses Voronoi diagram for solving it. It firstly introduces the principles of ordinary Voronoi diagram and generalized Voronoi diagram, then writes the corresponding program , lastly makes the application of Voronoi diagram in designating the influenced boundary of the economic object.
