可持续发展功能分区信息是区域空间规划与管理决策支持的重要依据,具有多维时空特征,采用地理信息可视化技术有利于从空间和时间角度揭示可持续发展功能分区信息中所隐含的规律与发展变化趋势。本研究利用可视化技术、组件式GIS技术和空间数据库引擎,开发了可持续发展功能分区可视化系统框架,包括数据源层、元数据层、软件构件层和功能模块层,实现了可持续发展功能分区信息的综合查询、结果显示与分析、图表可视化和地理可视化功能。在该系统框架基础上,本研究集成了全国1∶100万基础地理数据、分县社会经济统计数据和可持续发展功能分区体系,建立了中国可持续发展功能分区可视化系统,实现了数据信息和功能分区成果的可视化表达、图形和属性的双向查询、查询结果的统计分析、制作统计图表和制作专题地图,为政府部门、科研机构和公众了解和利用可持续发展功能分区信息提供了科学支撑。
The functional zoning information of sustainable development is an important basis for regional spatial planning and management decision-making support, with multi-dimensional spatio-temporal features. The use of geographic information visualization technology is conducive to reveal the laws and development implied in functional zoning information of sustainable development from a spatial and temporal perspective Trend. In this study, visualization technology, component GIS technology and spatial database engine were used to develop a functional visualization system framework for sustainable development, including the data source layer, metadata layer, software component layer and function module layer, to realize the functional partition of sustainable development Comprehensive information search, results display and analysis, visualization of charts and geo-visualization. Based on the framework of this system, this study integrated 1: 1 million basic geographic data, social economic statistics data and functional zoning system of sustainable development in China, established a functional zoning visualization system for sustainable development in China, and realized data information and Visualization of functional zoning results, two-way inquiries on graphs and attributes, statistical analysis of query results, production of statistical charts and production of thematic maps provide scientific support for government departments, research institutes and the general public to understand and utilize functional zoning information for sustainable development.
