【摘要】 从有形的地理信息系统到无形的空间信息服务,是地理信息系统在技术发展和应用需求双重驱动下的必然发展趋势。森林资源空间信息服务是以3S技术、网络技术、数据库技术等为基础,对获取的大量相关空间信息进行加工、处理和高效管理,通过方便快捷的访问、查询、发布、转换、下载、交换和应用等,为各类用户提供“一站式”服务,以满足森林经营和管理的要求,促进森林资源的可持续发展。用户层次角色的变化、用户环境的变化和服务对象的不同,都需要森林资源空间信息服务采取分级服务的方式。针对这些需求,本文采用多学科交叉研究、面向服务架构建模技术、抽象模型和具体应用相结合等多种方法,对森林资源空间信息分级服务进行了系统研究。首先,在分析不同用户对森林资源空间信息服务不同需求的基础上,对森林资源空间信息分级服务的理论技术基础进行了研究。其次,对森林资源空间信息分级服务业务视图模型和基于SOA的分级服务模型进行了研究。然后,在抽象的森林资源空间信息分级服务模型基础上,研究分级服务具体的实现过程。这是整个论文的核心内容,包括两个部分:第一,研究基于用户群和需求的服务分类的思路,即先根据用户群来进行服务分类,再根据用户的需求来进行二次服务分类,并实现了基于语义Web来描述元数据服务。第二,研究基于语义Web多重匹配的服务组合方式,利用Ford-Fulkerson和Dijkstra两种算法进行服务的功能性和非功能性多重匹配。最后,研究基于SOA架构的森林资源空间信息分级服务平台的设计与实现,主要包括森林资源空间信息分级服务的系统设计、系统运行环境和系统运行实例。研究成果包括如下几个方面:(1)在分析不同用户对森林资源空间信息服务不同需求的基础上,提出了森林资源空间信息分级服务的服务策略、服务方式和服务模式。(2)在基于组件建模技术和SOA参考模型的基础上,建立了森林资源空间信息分级服务模型,并实现了森林资源空间信息分级服务主动模型的方案。(3)提出了面向用户群和需求的多层次资源空间信息分级服务分类方法,并讨论了基于语义Web的方式对服务分类的描述。(4)通过对空间信息服务组合实现策略的研究,实现了森林资源空间信息分级服务基于语义的Web服务组合。(5)完成了森林资源空间信息分级服务原型系统的设计和开发。本文所做的工作为我国森林资源空间信息分级服务的研究和应用提供了借鉴,有助于其它相关研究工作的开展。森林资源空间信息分级服务系统以北京、福建和湖南等地的试验数据为基础,并在各地开展了应用示范,有力地促进了成果的产业转化,取得了较好的经济和社会效益。该系统的推广应用,对提高我国森林资源空间信息服务水平和服务方式,推动实现林业信息的共享和综合利用具有重要意义,因此其应用前景十分广阔。更多还原

【Abstract】 With the dual-driving of technology development and application demands, it is an inevitable trend for geographic information system develop from tangible GIS to intangible spatial information service. Based on 3S technology, network technology, and database technology, forest resources spatial information service can handle and manage a large number of relevant spatial information efficiently. Moreover, with convenient and efficient access, query, publication, conversion, download, exchange and application, it provides "one-stop" services for all types of users to meet the needs of forest resource management and facilitate the sustainable development of forest resources. The change of user’s level and/or user’s environment as well as the different service roles all need graded forest resources spatial information to provide services.In response to these needs, the thesis adopts the methods of interdisciplinary research, service-oriented architecture modeling techniques, combining abstract models and concrete application to study forest resources spatial information service systematically. Firstly, the thesis studies the theoretical basis of graded services of forest resources spatial information on the basis of analyzing different user different query towards services of forest resources spatial information. Secondly, the thesis probes into forest resources spatial information graded services business view model and SOA-based graded service model. And based on the abstract graded service model of forest resources spatial information, concrete implementation process of graded service is carefully studied. Core of this thesis as follows:(1) Studied how to classify the service based on user, then make a second classification of services by query, and implemented Semantic Web to describe metadata services.(2) Studied the pattern of service combination based on Semantic Web multi-match, utilising Ford-Fulkerson and Dijkstra to match function and non-function services.Finally, the thesis studies the design and realization of platform on forest resources graded spatial information services on the basis of SOA framework, including system design, system operation and system environment running instance of forest resources graded spatial information services.The research achievements include the following aspects:(1) To put forward the strategy, the methods and the models of the service of forest resources graded spatial information.(2) To build a graded service model of forest resources spatial information in the component-based modeling and SOA reference model. And to realise the program of active model of forest resources spatial information graded service.(3) To propose a classification method orients users and queries which graded services of forest resources spatial information. And to discuss the description approaches of service classification based on Semantic Web.(4) To achive combination of graded spatial information services of forest resources and Semantic Web based web after study the realising strategy of spatial information service composition.(5) To accomplish the designing and developing of a prototype system of graded spatial information services of forest resources.The thesis provides suggestions to the research and application of graded spatial information services of forest resources, helping to carry out other related research work. Based on the experimental data of graded spatial information services of forest resources in Bejing, fujian, and guangdong, the service has been applied extensively and strongly promoted the achievements of industrial transformation, achieved good economic and social benefits. Adoption of this system will improve service level and develop the services mode of our country forest resources spatial information service, it will also promot the realization of information sharing and utilization of forestry. This research has broad application prospects.更多还原
