Nowadays, the development of Digital Earth has made a tremendous impact on all aspects of human social life, and a series of effective work around Digital Earth, which attracted wide attention, have been carried out by people with different background. Meantime, exploitation of the popularized technology is constantly being mature with the development of Google Earth. However, users still have many difficulties in constructing and operating 3D scenes on web, because of the limitation of network speed. This paper aims to provide a more convenient method for the client users to interact with the 3D models, thus to promote popularization of Digital Earth technology and apply it in many aspects of social life. In this research, Ajax was utilized as a newly emerged network technology, since it could provide a good solution for application in developing of virtual reality technology based on Web. This paper analyzed the principles and key technologies of Ajax, explored how Ajax can be used in construction of interactive virtual reality scenes through case study, in order to enhance access speed of virtual scenes on Web page, and increase the authenticity, interactivity and extensibility of virtual scenes. This paper introduced the whole process of virtual model construction and proposed an efficient way to achieve interactive scene. The results showed that the combination of SAI (Scene Access Interface) method and Ajax technology could effectively save network bandwidth and enhance user experience, which laid the foundation for the development of virtual reality technology based on Web and the popularization of Digital Earth technology.
