中文摘要	本文以西部干旱区为例，在GIS技术的支持下，探讨了生态环境数据库的设计原理及方法。实践证明，在生态环境信息系统的建设过程中，数据的选择、数据库结构的设计、数据的查询与管理起到了举足轻重的作用，而本文在这方面的探索提供了重要的参考价值。同时，通过建立索引图和索引表的方式创新性地实现了遥感影像、图片、属性数据和文档等数据的空间查询与属性查询，打破了原有的单一属性查询方式。
英文摘要	This study focuses on the design and development of the Entironmental Information System of the Western Arid Land. The code and structure design of the Entironmental Information System are intro-duced. According to the characteristics of the environmental data, the database of the system was classi-fied into 6 sub-databases, including geographical vector data, hydrological and weather data, economic statistics, documents, theme maps and RS images or pictures, landuse or landcover theme data. With the ArcGIS software of ESRI as the development platform, the system is built by the way of built-in intergra-tion, combining VB with ArcObject as the development language. The system uses Geodatabase model to manage the attributes and spatial data. A geodatabase (short for geographic database) is a physical store of geographical information inside a database management system (DBMS). Geodatabase provides many advantages in managing geospatial data, migrating existing GIS datasets from either Coverages or Shape-files to the new Geodatabase format. Taking the western arid land as an example, this article has built the Entironmental Information Sys-tem of the Western Arid Land. In practice, the choosing of data, the structure design of structure and the management and query of database are very important, which are also the values of this paper. What’s more, through the establishment of index tables and index maps, we can also spatially query the data like picture, text and remote sensing data, which can only originally be queried by attributes.
