摘要虽然在实现数字地球愿景方面已经取得了重大进展，但目前的实现只能使集成和共享来自分布式源的空间数据变得容易，并且在集成用于模拟社会和物理过程的数据和模型方面的能力有限。为了实现决策的有效性，使用数字地球了解地球及其系统，新的基础设施，提供计算模拟的能力是必要的。本文提出了一个基于地理空间语义网的可互操作空间决策支持系统（SDSS）的框架，以扩展目前实施的数字地球基础设施的能力。介绍了异构本体集成、基于本体的目录服务、Web服务组合等主要技术。提出了本体匹配与集成的划分细化算法和Web服务发现与组合算法。拟议的可互操作的SDSS使决策者能够重用和整合地理空间数据和异构源跨互联网的可持续发展资源。基于该框架，实现了一个鲁南石林保护区边界划定原型系统，展示了基于本体的Web服务和面向服务的体系结构如何有助于开发可互操作的SDSS，以支持数字地球的决策。
Abstract While significant progress has been made to implement the Digital Earth vision, current implementation only makes it easy to integrate and share spatial data from distributed sources and has limited capabilities to integrate data and models for simulating social and physical processes. To achieve effectiveness of decision-making using Digital Earth for understanding the Earth and its systems, new infrastructures that provide capabilities of computational simulation are needed. This paper proposed a framework of geospatial semantic web-based interoperable spatial decision support systems (SDSSs) to expand capabilities of the currently implemented infrastructure of Digital Earth. Main technologies applied in the framework such as heterogeneous ontology integration, ontology-based catalog service, and web service composition were introduced. We proposed a partition-refinement algorithm for ontology matching and integration, and an algorithm for web service discovery and composition. The proposed interoperable SDSS enables decision-makers to reuse and integrate geospatial data and geoprocessing resources from heterogeneous sources across the Internet. Based on the proposed framework, a prototype to assist in protective boundary delimitation for Lunan Stone Forest conservation was implemented to demonstrate how ontology-based web services and the services-oriented architecture can contribute to the development of interoperable SDSSs in support of Digital Earth for decision-making.
