摘　　要：1.引言 二十世纪八十年代地理信息系统的突破发展,使得专门管理空间数据的数据库系统--空间数据库系统得到前所未有的广泛使用.近年来随着空间信息技术领域内遥感和测绘技术的飞速发展,包括资源、环境和灾害等的各种空间数据呈指数级数增长.With the rapid development of remote sensing and mapping technology and the widespread application of spatial database system, the spatial data collected and stored by human expand increasingly. These very large data sets far exceed human's capabilities of comprehending and handling, so the requirement of spatial data mining to provide human with valuable information becomes instant need. In this paper, the methods of spatial data handling in spatial data mining are discussed from a database perspective, the key problems of spatial data mining and their solutions in current study are presented, the relations between spatial data mining and geographical information system are analyzed.

关 键 词：地理信息系统 空间数据库系统 空间数据挖掘 数据处理
