摘要

为了全面查清全国土地利用状况，掌握真实土地基础数据，并对调查成果实行信息化、网络化管理，实现土地资源信息的社会化服务，满足经济社会发展、土地宏观调控及国土资源管理需要，进行了第二次全国土地调查并建立数据库。

土地利用空间数据的存储和管理是建设空间数据库的基础，考虑到信息共享和数据传输效率的需要，本文主要采用基于对象-关系型数据库的地理数据模型一Geodatabase 数据模型来建立土地利用空间数据库。Geodatabase地理数据模型实现了空间数据和属性数据的无缝集成和一体化管理，代表着GIS的发展方向.

本文介绍了Geodatabase数据模型并把Geodatabase数据模型应用到景泰县农村土地利用空间数据库建库研究上。首先根据CASE工具设计Geodatabase空间数据库结构模型，然后导入到ArcGIS中，然后再将转换后的数据加入到数据库中，并对数据库进行测试、维护和更新。

Abstract

The construction of Informationization is a force to accelerate the information technology development, and a significant way to scientifically manage land resource too. According to eleventh five-year-plan of land resource Informationalization and outline of cadastre, we will complete a series of database construction in order to support the land resource management and serve for public and also intend to establish urban and rural united database, which cover four levels (nation, province, city, country) and can communicate with each other.

The storage and management of spatial data are the foundation of the building of land use spatial database. For sharing and transmitting information efficiently, data model should be taken into account. Spatial data model experienced three generations: the CAD model, the Coverage model, as well as the third model of Geodatabase which was entirely based on object-Relational Database Management System. The Geodatabase model make the seamless integration of spatial data and attribute data come true and it represents the developing direction of Geography Information System. In this study, the Geodatabase data model was applied to the construction of Jing Tai land use spatial database. First of all, on the research and discussion of spatial database and the peculiar characteristic of Jing Tai land use management, the author has proposed to set up the thought of the land use spatial database with the Geodatabase model of object-oriented. CASE tools are used to create storage and management of land use model. In the thesis, using Geodatabase data model of ESRI and object-relation database management system integrates vector data、attribute data、raster data and original recording data together into the land use spatial database. The result of this thesis includes:(1) This study has designed and built Jing Tai Land Use spatial database based on Geodatabase with CASE tools.(2) Reference to international and domestic standard of metadata, the Jing Tai
