【摘要】 近年来,全球气候变化加剧,极端气象异常,地质灾害的发生越来越频繁,尤其是5.12汶川大地震,人们越来越认识到防范和减轻地质灾害对社会经济发展的重要性。地灾信息是国家防灾减灾战略信息资源,如何科学的利用地灾空间信息资源就显的尤为重要,同时灾区各级政府部门和社会大众对权威、可靠的地灾信息服务的需求与日俱增。地质灾害空间信息共享服务平台建设的根本是要建立一个空间信息共享的环境。在这个环境中,地灾空间信息可以在遵从统一规范和标准的前提下,以Web服务的形式供政府各机构、企业和大众共享。共享,包括内容的共享、对象的共享和共享途径等。随着物联网技术及“云计算”的发展,地质灾害管理不仅在管理机制软环境上有显著改革,在地质灾害信息共享方面也有了新的突破。论文提出面向服务的空间信息技术在地质灾害评价中的实践应用,通过SOA技术和GeoWeb2.0技术来实现地灾服务架构。论文探讨建立地质灾害空间信息共享规范,并以信息共享研究为核心目的,研究地质灾害基础数据及业务数据在生产、采集、处理、建库、发布、共享交换、服务聚合全过程的规范化。论文的主要研究内容和取得的主要成果包括:(1)从地灾空间信息共享服务平台建设现状入手,对地灾空间信息共享平台当前的需求做边界确定,包括:信息共享平台数据建设需求、应用服务需求以及系统性能需求,并探讨尤为重要的数据安全,提出地灾共享平台安全保密需求。在需求分析基础上完成空间信息共享模式设计。(2)引入地质灾害本体思想,提出研究区的多源异构地灾信息的集成方法:通过服务聚合和服务组合,实现多源、多尺度、异构地质数据的一体化描述、组织和管理,并进行设计空间数据库模型设计及实例验证。(3)依据地灾本体提出数据分类规则,依据地灾空间信息共享服务分层模型提出的地灾共享服务模式,设计并详细阐述符合极震区的地灾共享服务体系架构;基于共享服务平台设计汶川灾区地质灾害评价应用系统,阐述服务接口设计、评价应用以及最终的系统有效性验证。(4)通过在AppLogic平台上部署极震区地灾共享服务平台,建立地灾云GIS的原型,为西南地区今后提供地灾行业云GIS服务提供借鉴。更多还原

【Abstract】 With great changes in global climate and abnormal supreme weather in recent years, the geological disaster happened more frequently than before, so people attach more and more importance to the geo-disaster defending and decreasing for the social economic development especially after the big earthquake in Wenchuan, Sichuan province. As our nation’s great strategy informational source, Geo-Hazard information is the key technology in the area of government managing decision, it plays an important role in that project, how to use it has become the key problem. The development of new industry and promoting of life level, so the service based on the geo-information is in large needs.Geo-hazard spatial information sharing service platform is to build a basic spatial information sharing environment. In this environment, Geo-hazard norms and standards in compliance with the premise to the form of Web services for government agencies, enterprises and public sharing. Sharing, including sharing of content, shared objects and shared channels and other issues.Actually with the development of internet technology and cloud computing, the problem of shared geo-information has received primary achievement, so has the accordingly evaluation work. The paper advanced a theory and practical research geo-information technology that faced services in matter of geo-disaster evaluation. The foundation was based on the SOA and GeoWeb2.0 technology. And also the author suggested a standard system of management of geo-information, built up-to-date institution of spatial basic geo-data, spatial shared rules to realize the standardization of the process in data producing, gathering, dealing, building, releasing, sharing and changing as well as spatial information polymerization technique.The major content and achievement of this paper is set below:(1)From the standpoint of situation for spatial shared information service stage, the author made boundary decision for that stage and catalog for its users, then advanced spatial information shared mode. What’s more, according to the analysis for the needs of data construction, application services and systematic performance, and to the discussion of the data safety, the author made a request for shared stage secrecy needs.(2) Introduced the the idea of disaster ontology, proposed heterogeneous multi-source information integration approach to geological disaster: Service Aggregation Integration and service composition to achieve a multi-source, multi-scale, heterogeneous integration of geological disaster data, description, organization and management, and the design of spatial database and examples of model validation.(3)By mean of the disaster the idea of ontology, And then designed and elaborate the geo-shared service framework that is adapted to Wenchuan zone by using data catalog rules, geo-shared service model by Geo-hazard Spatial Information Sharing Service Model, another elaboration about the service interface design, its evaluation and application as well as effective system test was finished based on the Wenchuan geo-disaster evaluation and application system and shared service stage design.(4) By deploying the geological disaster shared-information services platform on the AppLogic platform to achieve the deployment of“geo-disaster cloud”prototype, which ,for the future , can be a reference in geological disaster service in southwest China.更多还原
