【摘要】：目前福建省统计局建设的福建统计信息网仍以传统的纯数字化、二维表格形式发布，不能满足日益增长的信息决策需求，无法体现其网站特色，发挥网站的最大功能。论文采用目前主流的富互联网（RIA）二次开发平台——Flex Builder的技术优势结合组件式Web GIS开发平台——MapGIS IGServer的控件可封装、可移植特点，设计并实现了基于地理信息技术相关功能的福建统计信息网站，将统计数据与其空间位置紧密结合，建立四维的地理空间数据库，实现专题统计数据的地图化、可视化、图表一体化。为社会的经济发展、统计决策等发挥其社会化服务功能。论文在参考国内外相关文献基础上，研究福建统计信息网的系统和技术特点，根据相关理论和技术实现或改进以下功能：（1）通过采集矢量地图数据和属性数据，构建四维（经纬度维、时间维、统计数据维）的福建省统计空间数据库；其数据库服务通过元数据系统服务器协调通讯。（2）采用MapGIS IGServer悬浮式面向服务地理信息平台，结合时下流行的鱼眼技术，设计实现了“福建统计信息网”平台，增加系统界面的美观，并且通过Grid格网索引优化了空间数据查询和动态索引优化索引方式，阐述基于组件式Web GIS架构的设计与功能方面的特色，体现RIA的Flex技术在改善用户体验，，重用GIS功能上的优势体现。（3）改进了传统统计数据二维表格发布形式，增强了数据的交互功能，实现了基于地理空间的统计专题图的发布方式，可直观的进行统计专题图的排版输出打印，以及在线进行统计数据挖掘。希望对统计局的数据发布方面有着更好的表现方式，让用户更方便快捷的进行统计数据的直观获取，方便为统计决策者提供决策依据。
[Abstract]:At present, Fujian Statistical Information Network, constructed by Fujian Bureau of Statistics, is still published in the form of traditional pure digitization and two-dimensional tables, which can not meet the increasing demand for information decision-making, can not reflect the characteristics of its website, and exert the maximum function of the website. In this paper, the components of MapGIS IGServer are encapsulated and portable, which is based on the technical advantages of Flex Builder, a popular secondary development platform of Rich Internet (RIA), combined with the component Web GIS development platform. This paper designs and implements the Fujian Statistical Information website based on the related functions of geographic information technology. It closely combines the statistical data with its spatial location, establishes a four-dimensional geospatial database, and realizes the mapping and visualization of the thematic statistical data. Chart integration. For the social economic development, statistical decision-making and other play its socialized service function. On the basis of reference to relevant literature at home and abroad, this paper studies the system and technical characteristics of Fujian Statistical Information Network, and implements or improves the following functions according to relevant theories and technologies: (1) collecting vector map data and attribute data, The four dimensional (longitude and latitude dimension, time dimension, statistical data dimension) of Fujian Province statistical spatial database is constructed, and its database service coordinates and communicates through the metadata system server. (2) using MapGIS IGServer suspension service-oriented geographic information platform, Combining with the popular fish-eye technology, this paper designs and implements the "Fujian Statistical Information Network" platform, which increases the beauty of the system interface, and optimizes the spatial data query and dynamic index optimization through Grid grid index. This paper expounds the characteristics of design and function of component-based Web GIS architecture, and reflects the advantages of Flex technology of RIA in improving the user experience and reusing GIS functions. (3) the traditional two-dimensional statistical data table publishing form is improved. The interactive function of data is enhanced, and the method of publishing statistical thematic map based on geographical space is realized. It can directly print the layout and print of statistical thematic map, as well as carry on the statistical data mining online. It is hoped that there will be a better way to express the data of the statistics bureau, so that the users can get the statistics data more conveniently and quickly, and provide the decision basis for the statistical decision makers.
