摘　　要：为了满足"一调""二调"等不同时期土地利用变化数据管理与分析的需要,文章在分析时态数据库构建中存在的问题的基础上,引入变更事件、重建事件和多基态,建立了基于事件组的多基态修正模型,实现了"一调""二调"土地利用数据一体化存储;针对"一调""二调"空间数据不一致的几何重建和语义转换问题,提出通过重建事件表实现重建前后要素归档及查询;同时,针对土地利用数据管理的现状以及数据形态,提出了土地利用变更增量提取、时态拓扑关系构建的方法,实现了土地利用时空数据库的构建。最后,以武汉市汉南区数据为例开发了原型系统,实验结果表明本文提出的模型、方法具有较强的实用性。In order to satisfy the requirement of management and analysis of land use data, by introdu- cing the concept of the event group and the multi-version into the events-based amendments data model, the integrated storage of the first and the second land survey data was realized in this paper. At the same time, aiming at the problem of semantic transformation and geometry reconstruction, the reconstruction event tables were employed to carry out the archiving and querying of features of different periods. Moreover, the implementation method for the extraction of incremental data and the construction of temporal topological relationships was put forward, and the spatio-temporal database for land use data was built. Finally, using the land use data of Hannan district of Wuhan city, a prototype system for the management and spatio-temporal analysis was developed. Experimental result showed that the proposed model and method would have good practicability.
