摘　　要：探讨并实现一种面向移动GIS的海量影像数据分发服务体系结构并对其关键技术进行探讨,在空间信息服务系统软件体系架构的基础上,提出了基于J2EE的海量影像数据分发的服务架构,并重点探讨了海量影像数据的索引、影像分发服务的多级缓存、基于服务集群的分发服务等关键技术。The lawn is one of the most important vegetation types, it is the renewable resource and raw material of husbandry in our country. It is also, the natural green protective blockade of the earth which plays an important role to human being. The water and the lush lawn around the Qinghai lake play the key role in control and regulation note only of the lake＇s ecological environment, but also to the eastern part. Therefore, the accurate prompt and effective examination on the vegetation change play an important role in the animal husbandry development, the Qinghai Lake ecological environment condition, and the ecology water demanding in this area. In this paper, the authors use the ASTER remote sensing image to extract vegetation index information and carry on the comparative analysis.
