在介绍基于云计算环境的GIS软件特点的基础上，指出缓存技术是影响基于云计算GIS软件发挥强大功能的关键因素，进而对各缓存技术进行比较，GIS软件缓存技术的主要目的就是减少对云数据库的查询，降低数据库的压力。通过研究，提出了基于云计算环境的GIS软件分布式缓存技术及其实现方法，给出了云计算GIS软件分布式缓存系统的结构以及数据交输的技术实现方法，提高了云计算GIS软件的用户体验度，降低了数据库的负担，充分利用了资源。%The characteristics of GIS software based on cloud computing environment is introduced,and on this basis,it is pointed out that caching technology is the key factor to affect on the function development of GIS software based on cloud com⁃puting. And then each caching technology is compared,it shows that the primary purpose of GIS software caching technology is to reduce the query of cloud database and release the database pressure. The GIS software distributed caching technology and its implementation method based on cloud computing environment are proposed according to research. The structure of the GIS soft⁃ware distributed caching system and technology implementation method of data delivery are given,which can improve the users′experience of GIS software based on cloud computing,reduce the database burden,and utilize the resource fully.
