摘要
地理网络的中心服务范围在实际生活中应用广泛，传统方法一般用等时区或等距区表示。本文给出基于地理网络的中心服务范围的概念，并在邻接结点矩阵的基础上，应用广度优先搜索算法确定一个中心的服务范围。
A center's service area of a geographic network is broadly applied in practical life. In traditional method, it is expressed by an isochronous area or an equidistance area. In this paper, basing on geographic networks, the conception of a center's service area is given. And the breadth first search algorithm is exercised on the adjacent node matrix to find a center's service area.
