【摘要】 土地信息系统(LIS)是地理信息系统(GIS)的一个重要应用，在地理信息系统中占有越来越重要的地位。传统的土地信息系统采用传统的GIS技术，基于C／S(Client／Server)结构，事务处理机制，网络功能，可移植性都比较差，已经不能满足时代的要求，也不符合软件技术发展的潮流。采用工作流管理(WFM)机制、组件式地理信息技术(ComGIS)，并基于B／S(Brower／Server)结构的土地信息系统才是解决LIS所面临问题的全新技术体系。 本文系统地讨论了土地信息系统的现状、特点及其发展趋势，并由此引出一系列的技术规范。论文详细阐述的技术及理论有：工作流管理技术及其与土地业务的结合原理；网络计算模式的发展，C／S结构与B／S结构的比较，实现B／S结构的主要技术手段ASP技术、COM技术及ActiveX技术的应用原理；新一代GIS技术ComGIS与WebGIS及它们的各自特点等。论文通过唐山数字土地系统这个应用实例来从系统结构的总体设计、软硬件环境、系统功能结构上探讨了上述技术的具体应用。在论文最后对本文提出的解决方案作了客观的总结，指出其优势与不足，并展望了未来土地信息系统的技术解决路线。更多还原

【Abstract】 The land information system (LIS) is an important application of the geographical information system (GIS), playing a more and more important role in the GIS. The previous LIS, which based on the C/S (Client/Server) framework and traditional GIS technology, is inefficient in the transaction processing, the function of the network and the portability. So, it can’t yet satisfy the request of time, and can’t keep up with the development of the software technology. The whole-new technology system, LIS, which has the basement of the Workflow Management (WFM) and ComGIS and B/S (Broswer/Server) framework, can solve all problem that LIS faces.This article systemly discussed the current situation, characteristics and development trend of the LIS, drawing the following technologies. There go the detailed technologies: the Workflow Management Technologies and their combination principles with the land business; the development of network computing mode, the comparison of the C/S framework and the B/S framework, the application of ASP, COM and ActiveX which are the main methods to struturing the B/S framework; the advanced ComGIS and WebGIS as well as their respective characteristics. Take Tangshan Digital Land Information System, this article probed into the concrete application of the above-mentioned technologies on the general design of system structure, software-hardware environment and,system function structure. At last the article put forward an objective summary of all the resolutions to the LIS, pointing out its advantages and disadvantages, looking forward to the future of LIS.更多还原
