摘　　要：研究目的:基于当前土地管理空间数据异构严重,难以共享的现状,探索空间数据共享的根本解决方案,实现土地管理空间数据的一体化应用。研究方法:通过研究土地管理空间数据异构的原因和空间数据共享的发展过程,提出获取土地管理空间知识,构建知识本体,建立映射模型,实现基于模型的空间数据共享的方法,并开发相应的共建数据共享平台进行了实证研究。研究结果:基于知识本体的土地管理空间数据共享方法实现了数据与应用软件的松耦合,最大限度的降低了空间对象的信息负载,有效的解决了土地管理空间数据共享的问题。研究结论:基于知识本体的空间数据共享方法是目前最有效的空间数据共享应用的解决方案,与GIS未来的发展趋势相吻合,对实现异构空间数据的共享应用有普遍的借鉴意义。Research purposes： based on the status quo of land management relating to the difficulty of sharing of spatial data seriously heterogeneous, this paper was seeking to an assessment on solutions essential to realize the sharing of spatial data in order to have access to an application for integrating spatial data in land management. Method： through the research of what causes the scenario of the heterogeneous spatial data and the review of the historical process of spatial data sharing, the author of this paper was revealing some methods that could assist in acquiring knowledge on the management of space, the construction of the ontology mapping and model so we may realize the sharing of common spatial archives with an empirical study to build as well as develop a platform of the sharing of appropriate data. Results： The method of the ontology-based about sharing the spatial data of land management can realize the loose coupling of data and application software and the maximum reduction of the burden of the spatial information object. Conclusion： The ontology based on the sharing of spatial data will be far the most effective solution to the application that is also found in the next trend in GIS. This coherence can play a significant role in the reference of the application-sharing conditional on the heterogeneity of spatial data on a global scale.
