论文探讨了WebGIS应用中瓦片地图的加载方式，提出了一种地图加载的方法，该方法能解决传统加载方法存在的地图浏览时边缘白边，服务器负载大等问题。该方法综合内存LRU调用算法、浏览器缓存机制和异步调用技术，是一种多层架构模式的优化方法，并给出了该架构模式的实现策略与步骤，为封装功能更强、用户体验更好的WebGIS组件提供了技术理论依据。

This paper discusses a tiled map loading method of WebGIS ,puts forward a method of maps loaded ,which can solve the problems ,such as White border edge of map ,and server load large when loading tiled map using the browser . This method is an optimizing method of multi‐tier architecture model ,that has integrated memory LRU algorithm ,the brow‐ser cache mechanism and asynchronous .Giving the steps of the implementation strategy provides a good theoretical basis for packaging more powerful function ,better user experience WebGIS technology component .
