摘　　要：随着地理信息系统和网络技术的发展,空间数据的处理正深入到各个专业应用领域。分布式地理信息系统是当前GIS领域的一个发展方向。该文研究的重点是探讨通过组件技术构造分布式三维地理信息系统的方法,以及在此基础之上如何给用户提供一种简单方便的应用模式。最后,基于COM+机制,采用多线程技术实现了一个DGIS三维演示系统(ThreeDem),并进行了模拟应用。With the developing of GIS and network technology,handling of geospatial data has been integrated into all aspects of special domains.Distributed GIS(DGIS)is a very hot theme at present.The paper focuses on the technology that is how to construct distributed 3DGIS based on Component technique,and giving a simple mode to apply this technology to Distributed GIS.Finally,the ThreeDem system based on COM+ technique programming method is constructed,From this system,we can consider that the distributed 3DGIS based on COM+ technique can solve the difficulty in face of distributed 3DGIS at the present time.
