摘　　要：数据更新是土地利用数据库的重要功能,然而当前的数据库联动规则设定内容过于陈旧和繁琐,导致土地利用数据库更新后的数据质量较差。基于此,设计了基于遥感影像测绘的土地利用数据库联动更新方法:首先使用9I模型对原始数据进行处理,以确定并获取遥感影像测绘数据拓扑关系;提取其增量信息,再构建多层级联动规则;进而根据聚合算法实现土地利用数据库联动更新。然后构建实验环节对新方法的数据更新能力与传统方法进行了充分的比较与分析,结果表明,新方法采用后数据库中数据质量得到控制与提升。The data updating is an important function of land use database. However, the current database linkage rules are too outdated and cumbersome, resulting in poor data quality after land use database updating. Based on this, this paper designs a linkage updating method of land use database based on remote sensing image mapping. Firstly, the 9I model is used to process the original data to determine the topological relationship of remote sensing image mapping data. The incremental information is extracted and the multi-level linkage rules are constructed. According to the aggregation algorithm, the linkage updating of land use database is realized. Then the experimental link is constructed to fully compare and analyze the data update ability of new method and that of traditional method. The experimental result shows that the data quality of database can be controlled and improved after the new method is adopted.
