提出加权Voronoi图的一种新形式———投影加权Voronoi图,由此形成平面剖分中的空隙(竞争三角形)可用于GIS空间竞争分析模型。进而分析不同的剖分模型以及竞争三角形的特性和分布。最后提出这种空间分析方法的应用领域。
A new form of weighted Voronoi diagrams named Projective Weighted Voronoi Diagram (PWVD) is introduced. Thus the interspace produced by tessellation can be used in GIS spatial competition analysis model. Several different partition models and competition triangles attribute and distribution characters are discussed. The final section shows some potential applications of the analysis method.
