摘　　要：针对Internet环境下大量分布、异构空间数据难于共享的问题,本研究在SOA理念指导下,结合WebServices和传统WebGIS数据共享技术,提出了一种新的面向Web服务的网络空间数据共享模型,并对模型的构成、运行过程进行了描述。此外,文章还以ArcIMS和MapXtreme两种WebGIS平台为例,检验了该模型的可行性。结果表明:此模型能较好地实现不同WebGIS系统间的互操作,从而为Internet环境下的分布、异构空间数据共享提出了一种新的解决思路。In order to solve the problem of a great lot distributed and heterogeneous spatial data sharing in Internet, this study firstly proposed a web services - oriented model for spatial data sharing under the guidance of SOA framework, which integrated the web services with the traditional WebGIS technologies. Then, it described the construction and the operation process of this model. Finally, taking ArcIMS and MapXtreme, two kinds of WebGIS platforms, as example, the feasibility of this model was validated. The results revealed that this model is effective to realize the interoperation among different WebGIS systems, and hence can be regarded as a new idea to work for the sharing of the distributed and heterogeneous spatial data in Internet.
