摘　　要：林业大数据已进入全时空信息系统时代,为满足其多元化需求,提出了基于MDA模型驱动架构的林业多维时空大数据可视化应用设计及模型构建。结合MDA模型驱动架构三级建模方法,构建林业时空大数据可视化的CIM模型、PIM模型、PSM模型。平台架构前端采用HTML5+JavaScript编程语言,根据前端系统特点选择不同的JavaScript框架。后台采用JAVA为开发语言,应用Spring MVC+myBatis搭建基础框架,实现系统的基本业务功能和通用功能,并在依托Spring框架集成流程管理activiti、安全认证shiro、日志管理log4j和缓存redis组件,开发了林业多维时空可视化系统。结果表明,该系统应用于内蒙古林草局林业大数据管理平台,实现了从时间、空间等不同维度对林业资源数据进行检索、统计分析及展示等功能,具有良好的适应性和扩展性,并预留相关字段与接口,能够满足不同领域用户复杂多变的需求。In order to realize diversified demands in the era of forestry big data full time and space information system,this study designed and constructed a dimensional spatiotemporal visualization of forestry based on model driven architecture.The CIM model,PIM model and PSM model of forestry space-time large data visualization were constructed by combining the three-level modeling method of MDA.HTML5+JavaScript programming language and different JavaScript frameworks were selected for the platform architecturefront-end,basic functions of the system were realized based on JAVA background and Spring MVC+myBatis basic framework,manage component activiti,secure authentication shiro,log manage log4j and cache redis component were integrated with the Spring framework.The forestry multidimensional visualization system was ultimately developed.The results showed that the system was applied to the forestry big data management platform of Inner Mongolia Forestry and Grass Bureau,realizing the functions of retrieving,statistical analysis and displaying forestry resource data from different dimensions such as multidimensional space and time,and had good adaptability and expansibility,meeting the complex and changeable application requirements of users in different fields.
