空间矢量数据的存贮方式与索引机制直接影响到地理信息系统的整体性能 ,对它们发展的了解有助于地理信息系统的使用与开发。介绍了空间矢量数据的存贮方式和索引机制的演变过程 。

With the expansion and deepenning of GIS application, the data amount of GIS is increasing constantly, and the data model of GIS is more and more complicated. How to store and manage the magnanimity data and how to offer a high-efficient datum index mechanism become key problems of GIS field. The data index can solve the issues how to visit, draw and analyse the necessary data fast from the magnanimity data.The approaches of storage and index for spatial vector data affect directly property of GIS, so it is helpful for application and research of GIS to understand their development. This paper introduces the development of approaches in storage and index for spatial vector data, and summaries their characteristics.
