【摘要】 论文在分析空间数据库的研究现状、发展趋势及空间数据库建设关键技术的基础上，探讨了松辽流域水资源管理大型空间数据库系统的建立方法。对于松辽流域水资源综合规划、管理和决策数据平台建设以及提高松辽流域水资源管理的信息化水平具有重要意义。论文实现了基于Oracle Spatial空间数据库和MapX组件技术的各项主要功能开发（包括数据输入与编辑、空间检索与查询、统计分析、空间分析、决策分析、数据输出等）；解决了海量空间数据与属性数据的无缝集成、查询检索，空间数据完整性、一致性维护，分布式数据处理与维护、事务处理，制图和数据安全性控制等问题。全文共分为五部分，第一章阐述空间数据库管理系统的研究现状、发展趋势，以及松辽流域水资源管理大型空间数据库建设的目标和意义，并说明本研究的数据资料来源和工作路线。第二章综述大型空间数据库建设的关键技术（包括海量空间数据集成管理、矢栅一体化技术、多源空间数据无缝集成、空间数据库引擎、空间数据的多重表达等）。第三章介绍本文的研究区域——松辽流域的自然及社会经济概况。第四章研究基于Oracle9i Spatial建立松辽流域空间数据库的方法，包括松辽流域空间数据库元数据管理、空间数据的访问、空间索引以及空间数据的组织等。第五章进行松辽流域水资源管理空间数据库系统开发研究，包括数据库准备，数据采集、编码、上载，空间数据库配置，系统功能实现等。最后提出本文的研究结论。更多还原

【Abstract】 The thesis analyses firstly the research status, development trend and key construction technology of spatial database. Then the construction methods of Water Resource Management Large Spatial Database System for Song-Liao River Basin are discussed. This study is important for Song-Liao River Basin water resource comprehensive plan, management, decision-making data construction and significant for the improvement of Song-Liao River Basin water resource information management level. Based on “Oracle spatial” and “MapX”, the thesis achieves main function exploitation of the system, including data import and edit, spatial searches and query, statistic analysis, spatial analysis, decision-making analysis, data export and etc. The thesis also resolves a series of questions such as seamless integration of huge spatial data and attribute data, query and searches, spatial data maintenance of integrality and coherence, distributed data process and maintenance, transaction processing, cartography, data security control and so on.The thesis is divided into five chapters as follows: The first chapter introduces the research status and development trend of spatial database management system, explains the construction aim and significance of Song-Liao River Basin Water Resource Management Large Spatial Database System, shows the source of the data and materials using in the study, and demonstrates the work flow. The second chapter summarizes the key technologies of large spatial database construction, including huge spatial data integration management, vector and grid data integrating method, seamless integration of many source spatial data, spatial database engine, spatial data multiple representation and etc. The third chapter introduces the study area, including its nature environment and social economic development. The forth chapter studies the construction methods of Song-Liao River Basin spatial database based on “Oracle9i Spatial”, including Song-Liao River Basin spatial database metadata management, spatial data accessing, spatial index, spatial data organization and so on. The fifth chapter discusses the development methods of Song-Liao River Basin Water Resource Management Large Spatial Database System, including database preparation, data collection, encode, uploading, spatial database configuration, system function realization and so on. At last the research conclusion of this thesis is stated.更多还原
