摘　　要：基于8-交集模型,加入可对一类带洞区域和简单区域间拓扑关系进行约束的条件,对其拓扑关系进行表示,得到了一类带洞区域和简单区域间的17种拓扑关系.通过对一类带洞区域和简单区域间的17种拓扑关系进行研究,建立了拓扑关系推理系统,并建立了17种拓扑关系的推理复合表.根据拓扑关系复合表,通过对目标试验田区域和降雨云区域的拓扑关系进行推理,计算出各种灌溉概率,并制定出有效的灌溉机制,从而优化水资源的利用.On the basis of 8-intersections model,constraint conditions can be added to topological relations between a region with holes and a simple region so as to represent the topological relations.According to the research of topological relations between a region with holes and a simple region,we established the system of topological relation reasoning,and got the composition table of 17 topological relations.We calculated all kinds of irrigation chances and drew up the effective irrigation mechanism via the topological relations sheet.Reasoning the topological relations between the target region and the rain cloud area,we are able to optimize the use of water resource.
