Qualitative spatial reasoning researches representation and process of human ’ s qualitative cognition for spatial objects and their relations in geometric space 定性空间推理研究的是人类对几何空间中空间对象及其关系定性认知常识的表示与处理,面对的是空间对象的定性特征和定性关系。
Firstly , this paper introduces the basic conception , investigation background and contend and actuality of qualitative spatial reasoning and component technology , and confirm the related study fields 论文首先介绍了定性空间推理和组件技术的基本概念、研究背景、研究现状,确定了论文研究的内容。
In recent years , spatial reasoning has great development , at the same time it promote the development of gis which has become the most widely and mature application domain of spatial reasoning 近年来，空间推理的快速发展，也促进了gis的发展，地理信息系统成为空间推理最成熟也最广泛的应用领域。
Firstly , the thesis introduced gis and the basic conception , investigation background and contend and actuality of spatial reasoning , confirm the related study fields of the thesis 论文首先介绍了地理信息系统以及拓扑空间关系，空间推理的基本概念、研究背景、内容和现状，确定了论文研究涉及的相关知识领域。
Different from the researches of modeling , descriptions , representations , relations ’ analysis and processing of spatial objects in spatial reasoning researching , qualitative spatial reasoning faces to the qualitative characters and qualitative relations of spatial objects 不同于空间推理研究空间对象的建模、描述、表示及其关系的分析和处理,定性空间推理面对的是空间对象的定性特征和定性关系。
The aim of our work is that we do thorough research on spatio - temporal data , spatial reasoning , gml , svg , and combined them with webgis technology , design and develop the spatio - temporal data management middleware , which can be integrated into the platform . usually , people develop webgis based on various existing webgis developing products . but the prices of these products are too expensive 我们所做的工作的目标就是对时空数据、空间推理、 gml 、 svg等技术进行深入的研究,并将其与webgis技术结合起来,设计并开发实现时空数据管理中间件,并将我们的研究成果做为一个组成部分集成于整个平台当中。
Secondly , the paper concretely introduced the topological spatial relationship and spatial reasoning , especially , it gave the contend , theory dependents and the study method of spatial qualitative reasoning . on the other hand , the thesis provided the method that put the spatial reasoning into topological spatial relational analytical study 其次具体介绍了拓扑空间关系和空间推理，尤其是空间定性推理研究的基本内容、理论依据、研究重点、难点、研究方法，提出将空间推理的方法和推理机制引入到拓扑空间关系的分析研究中来。
Further , the paper put the spatial reasoning in practical use of topological relational analysis . the complex and hierarchy reasoning used in topological reasoning was introduced into the analysis of directional spatial relationship . for the first time , the paper gave the ideas 再次，将空间推理的方法具体应用到拓扑关系的分析中，将拓扑推理中用到的复合推理和分层推理的方法引入到方向空间关系的分析上来，首次提出在拓扑和方向复合推理的基础上，将两者有机结合，进一步进行拓扑推理的思想，并探讨了相应的规则。
