空间拓扑关系是GIS理论研究中的基础性问题，对地理空间数据的组织管理、分析查询具有非常重要的作用。本项目针对当前缺乏对模糊拓扑关系表达的尺度效应和应用适宜性方面的研究，根据模糊空间对象拓扑关系的特征机理，探讨了模糊拓扑关系的尺度效应，给出了不同尺度下较合理的模糊空间对象的定义，进而建立一种简洁、实用的拓扑关系描述模型，最后利用多种比例尺的土地利用数据对模糊拓扑关系的应用适宜性进行验证。所做主要工作如下：1）将模糊数学、Rough集理论相结合，分清不同尺度下的模糊对象的特点，给出较合理地的模糊空间对象的定义，充分体现其模糊性；2）在此定义基础上，总结、分析模糊空间对象拓扑关系的特点，比较分析现有模型的优缺点，探讨较全面、完备的模糊拓扑关系模型，并编程实现该模型；3）利用多种比例尺的土地利用数据对模糊拓扑关系的应用适宜性进行验证。研究成果将完善GIS拓扑关系的理论与方法，促进GIS的发展。

Spatial topological relations is a basic problem of GIS theory studying, which playing an important role in the organization, management, and analysis of geospatial data. This project currently has addressed the lack of researches on the scale effects and suitability of the expression of the fuzzy topological relations, according to the character of the fuzzy topological relations, explored the effect of the scale of the fuzzy topological relations, given a more reasonable definition of fuzzy spatial objects of different scales，then established a simple and practical topological relations model. Finally, it used the multi-scales land-use data verified the application suitability of fuzzy topological relations. Main tasks as follows:1)Combined the fuzzy mathematics and rough set theory, distinguished the characteristics of the fuzzy objects on different scales, given a reasonable definition of the fuzzy space objects，fully embodied its' ambiguity.2)On the basis of this definition，summarized and analyzed the character of the fuzzy topological relations of spatial objects, comparatively analyzed of the advantages and disadvantages of existing models, explored more comprehensive and complete fuzzy topological relations models, and programmed those models by computer languages.3)Used the multi-scale land-use data to verify the suitability of the application of fuzzy topological relations. The achievement will improve the theory and methods of GIS topological relations, as to promote the development of GIS.
