摘　　要：基于地理信息系统,分析了地质灾害空间数据库建设过程中存在的问题,提出了相应的解决措施。通过灵活运用GIS软件的各种功能,提高了属性数据库质量和录入属性卡片的效率,并建立统一编码实现内部属性库与外部数据库的紧密关联。经实际运用,获得诸多成效,满足系统查询、统计、输出等各项功能的要求,能反映余姚市地质灾害的现状,为余姚地质灾害防治工作的日常管理、监测预警,提供决策支持和应急处置办法,实现了各级地质灾害管理部门对地质灾害点及其相关资料的网络化管理和动态更新,为防灾减灾工作的开展提供了指导作用。Based on the geographic information system (GIS), the problems existing in the construction of the geological disaster space database are analyzed, and corresponding solutions are put forward. Through the flexible application of the various functions of the GIS software, the quality of the attribute database and the efficiency of the input property card are improved, and the unified coding is established to realize the close association between the internal property library and the external database. Through practical application, and obtained many results, meet the system various functions such as query, statistics, output requirement, can reflect the status quo of Yuyao geological disasters, for Yuyao daily management, monitoring and early warning of geological hazards prevention and control work, to provide decision support, and emergency disposal measures to implement the geological disaster management departments at all levels in geological disaster sites and its related information network management and dynamic update, provides guidance for disaster prevention and mitigation work.
