摘　　要：受限于移动设备运算能力和三维地图数据网络传输速度,如何在快速移动端流畅地显示月球三维地图,展示月球形貌细节,还是一个难点。为解决这一问题,本文首先考察已有的移动端三维地图实现方法,在此基础上研究了一种基于前后台异步渲染策略的三维月球地图实现方案;基于嫦娥月球数据,构建了一个月球三维形貌地图原型系统,并成功应用于移动端的嫦娥月球三维形貌数据发布。Restricted by the computing capability of the smart mobile devices and the speed for 3D map data transmission through mobile internet, how to display the 3D lunar map on mobile devices smoothly and represent the lunar topography in detail is still a problem. To solve this problem,the state of art for mobile 3D map was investigated, and based on the work, an asynchronous rendering strategy for 3D Lunar Mapping on mobile devices was proposed. With the method and Chang＇ E lunar data, a 3D lunar map prototype system for mobile devices was developed and successfully implemented in the program for Chang＇ E lunar topographic data release.
