摘　　要：针对地理信息服务中兴趣点查询检索过程中的拓扑判定问题,描述并分析了兴趣点要素之间的空间拓扑关系,设计了一套点/面、线/线和面/面拓扑关系判定的规则,将面/面目标之间的拓扑关系判定通过分解的方式,转化为点/面目标拓扑关系和线/线目标拓扑关系进行判定。并以某市公共自行车租赁点及其周边服务范围之间的拓扑关系分析为例,通过规则和算法实现了公共服务兴趣要素之间拓扑关系的判定。试验表明,面/面目标之间拓扑关系判定规则具有完备性和有效性,为地理信息服务中类似的拓扑查询、判定提供了有效的参考。According to the problems of topological decision in query and retrieval of interest points in geographic information service,this paper describes and analyzes the spatial topological relations between points of interest factors,designs a set of rules for determining the relationship between the point/area,line/line and area/area topology.This strategy presents a way of judging the topological relationship between area/area objects.The topological relation between the area/area targets is determined by decomposing,converted to point/area target topology and line/line target topology to determine.The proposed rules are applied to public bicycle rental stations and the fields around them within a certain distance（e.g.1 km）.Experimental results show the advantages of the proposed rules and method,demonstrating a functional and promising solution for determining the topological relation betweenpoint and areal objects accurately.It provides an effective reference for similar topological query and decision in geographic information service.
