摘　　要：针对安徽省地理国情普查数据库管理系统建设过程中,遇到的加载大数据量图层时显示速度慢的问题,本文设计了一个基于MongoDB数据库存储地图瓦片,数据库管理系统联动调用库体成果的技术方案。实践证明,该方案很好地解决了地理国情普查数据库管理系统访问大数据量图层显示慢的问题,同时在遇到瓦片数据文件量急速增大的情况,可以有效地避免数据存储和访问性能间瓶颈问题的产生,具有参考和推广价值。To deal with the problem of lowly speed when large volume data was loaded in the process of constructing Anhui geography and national conditions census database management system,we design a technical scheme based on MongoDB database to store map tile.Practice has proved that the scheme can efficiently solve the slow access to the large amount of map layers of geographic conditions of census database management system.At the same time,it can effectively avoid the bottlenecks of data storage and access performance when encountering the rapid increase of tiles data files.The program has a reference and promotion value in the construction of geographical conditions census database.
