摘    要:地理信息世界存在地理空间、定位空间、数学空间等3大空间,且这3大空间存在着一一对应的关系。该研究在探讨地方独立坐标系统建立方法和特征的基础上,提出了根据地理空间及其对应的定位空间将数学空间进行分区的设想,从而将农村和城镇的土地信息表达到一个数学空间,实现了将一个区域内的土地信息完整、连续地管理和表达,为城乡一体化地籍信息系统的建设提供了有益的参考。

关 键 词:地籍信息系统  城乡一体化  土地数据库  坐标系统

Abstract:There are three spaces in geographic information: geo-space, location space, mathematical space, and these three spaces have rela- tionship of one-to-one correspondence. Based on the discussion of building method and feature for an local independent coordinate system, the author put forward a vision which zone mathematical space according to the geo-spatial and corresponding location space, thereby rural and urban land information will be expressed into a same mathematical space, achieving that the land information in an area can be managed and expressed completely and continuously. This method provides an useful reference for building the urban-rural integration cadastral information system.
Keywords:Cadastral information system  Urban-rural integration  Land database  Coordinated system
