【摘要】 传统土地利用规划管理系统业务流程固化,不能满足现代土地利用规划管理的需要。本文采用工作流技术,研究一种面向业务流程的土地利用规划管理系统,并在此基础上探讨其中的关键技术。文章首先分析了传统土地利用规划管理系统中流程管理方面存在的不足,针对其应用复杂、业务流程表现晦涩、缺乏项目和组织机构管理能力、重用性和可扩展性差等弱点,提出将工作流技术与GIS集成引入土地利用规划管理系统的解决方案。其次,探讨了组件技术、组件式GIS技术、工作流技术和空间数据版本管理技术等。然后,详细分析了面向业务流程的土地利用规划管理系统的数据库设计和功能模块设计,实现面向业务流程的土地利用规划管理系统。基于上述内容,文章重点分析了面向业务流程的土地利用规划管理系统中的关键技术及其实现方法,包括:工作流建模、ArcSDE版本管理、数据格式转换、地类面积统计。工作流技术在系统中的应用,实现了业务流程的灵活定制;而将ArcSDE版本管理机制引入系统,很好的解决了传统并发访问控制效率低的问题,实现在系统中能够支持多人同时对规划图件数据进行编辑的功能;数据格式转换功能实现了系统数据来源和数据输出的多样性,提升了系统的数据管理能力;地类面积统计功能实现了土地利用规划业务中地类面积的实时统计,辅助土地利用规划的编制。更多还原

【Abstract】 The defects of traditional land-use planning management system such as lack of validation control can’t satisfy the demands of modern land-use planning management.Based on the workflow modeling of land-use planning management,a workflow model applicable to GIS and its related technologies and methods are studied.Firstly,the defects of traditional land-use planning management system are analyzed, such as complexity,obscure business process performance,lack of project management and organizational capabilities,poor reusability and expandability.Therefore,according to the advantages of workflow,a solution integrating workflow and GIS is put forward.Secondly, component technology,component GIS technology,workflow technology and version management of spatial data are discussed briefly.Then database design and functional modules design of the solution are analyzed in detail,and business process oriented land-use planning management system is implemented.Based on the studies above,the development and implement of some key technologies, such as workflow modeling technology,ArcSDE version management,data format conversion and land area statistics are analyzed.The application of workflow technology implements the flexible customization of business process.The introduction of ArcSDE version solves the traditional problems with low efficiency in concurrency access control and allows multiple users to edit the same land-use planning data in an ArcSDE geodatabase without applying locks or duplicating data.The function of data format conversion achieves the diversity of data input and output,and improves the capability of system’s data management.The function of land area statistics provides real-time statistics in business of land-use planning and supports the establishment of land-use planning.更多还原
