摘　　要：将地理学中腹地的基本理念引入到物流园区辐射范围的研究中,并特别地提出了"物流园区腹地"的概念。其后,立足于计算几何中能反映空间划分连续性优势的Voronoi图方法,通过将断裂点模型中的"规模"参数引入到加权Voronoi图中,构建了基于加权Voronoi图的物流园区腹地界定模型。最后,根据成都市"四中心"的规划实例对该模型进行了实际应用,并通过GIS软件的应用操作实现了对"四中心"各自腹地的界定。实践证明此方法较好地克服了断裂点理论和Voronoi图等单一的传统空间划分方法所存在的缺陷,使物流园区腹地的界定更具合理性和科学性。The concept of hinterland in geography was introduced into the research of the radiation scope of logistics park, and the concept of logistics park hinterland was particularly proposed. Subsequently, based on the Voronoi diagram theory in computational geometry which reflects the advantage of continuity of space division, and by introducing the ＂ scale＂ parameter in the breaking-point model into weighted Voronoi diagram, the model for defining the logistics park hinterland based on weighted Voronoi diagram was built. Finally, this model was practically applied to the planning example of ＂Four logistics centers＂ in Chengdu, whose respective hinterlands were also defined by means of GIS software. It practically proves that this model overcome the shortcomings existing in the conventional single space division theories and methods such as the breaking-point model and the ordinary Voronoi diagram theory, and made the definition of logistics park hinterland more reasonable and scientific.
