摘　　要：网络地理信息系统日趋复杂化,使得需要处理的数据规模越来越大,对客户端数据读取速度的要求越来越高。为了提升网络地理信息系统中对客户端的响应效率,本文提出并实现了新一代的地图瓦片缓存方案。实践表明,地图瓦片的分布式缓存设计提高了客户端浏览地图的速度,提升了大量并发用户的访问性能。As Web Geography Information System is getting complex, the data size increases tremendously and the client data requires faster access speed.To improve the efficiency of the clients on WebGIS,a new generation of map tile buffer solution is proposed and implemented. Finally,it is demonstrated by the practical application that,in use of the design of distributed cache tile data,the speed of the client browsing the map is improved and the performance of a large number of concurrent user accesses is enhanced.
