英文摘要：

In this paper, the GIS basic technology system is described. According to the GIS application progress, the new generation GIS technology,which focuses on distributed and peer to peer computing,is presented. At first,this paper discusses the history of GIS technology progress and the basic technical characteristics of past generation GIS software. Based on it the trend of GIS application progress is analyzed and the basic technical characteristics of new generation GIS software are presented. From the points of spatial data model,spatial query language and spatial data distributed computing, the technical and theoretical system is discussed in detail and the feasible implement mechanisms and the new generation GIS prototype are presented.
