摘要
为了帮助林业决策者更好地分析林业统计数据并最大化利用林业统计数据的价值,以《中国林业产业及林产品年鉴》中的林产品产量数据为例,设计并开发了一种可兼容多种林业宏观统计数据源的数据可视化系统。系统采用B/S架构,整体为网络应用常见的三层结构,并在前端接入百度地图JavaScript API与Echarts插件实现了主要的可视化功能。由于系统能够通过前端API与插件从系统外部获取空间数据、地图底图、图表模板等可视化材料,故对系统内部的数据要求和可视化材料要求较低。设计能够显著降低林业统计数据的可视化难度,且对以行政区域为统计单位的林业统计数据可视化系统搭建具有普遍的兼容性和复用性。整个系统能够以电子地图和数据图表为载体,向林业相关决策者提供林业统计数据的可视化服务,给林业统计数据的分析和挖掘工作提供辅助支持。
In order to help forestry managers analyze forestry statistical data better and maximize the value of forestry statistical data,this research designed and developed a data visualization system that is compatible with various forestry statistical data sources,taking the forest product output data as an example.The system adopts B/S architecture,with a common network application structure of three tiers.The data visualization is mainly realized by Baidu map service and Echarts at the front-end tier.The system can automatically obtain the geographic data,base map,chart templates,and other visual materials from the outside of the system through the front-end API and plug-ins.Therefore,the requirement of the data and visual materials inside the system are very low.The design can significantly reduce the difficulty of forestry statistical data visualization and has common reusability for the visualization of forestry statistical data which is collected as the administrative region unit.After development,the system can provide forestry statistical data visualization service to forestry decision-makers.The service,which can show the visualized data on the electronic map and charts,can effectively support the forestry decision-making and data mining.
