统计信息与空间信息按地理格网集成的方法研究

统计信息是区域可持续发展中的重要信息资源,涵盖了人口、农业、工业、经济等各类数据。采用GIS技术,有效地实现统计信息与空间信息的集成管理是区域可持续发展的重要保证。本文在分析了GIS中常用的集成方法基础上,提出了通过统计信息的“空间化”实现两者集成的方法,并以人口为例,详细论述了通过“空间化”实现人口数据与空间数据的集成过程。通过这种集成,可以高效地利用GIS的分析功能实现统计信息的管理、分析、显示。

Preliminary study on integration method of statistical data and spatial data based on grid

Statistical data is an important information resource of sustainable development of territories, including data of population, agriculture, industry, and economy, etc. It is an important guaranty for sustainable development of territories to integrate efficiently statistical data and spatial data by GIS technology.This paper analyzes common methods of integrating statistical data and spatial data in GIS, then puts forward a method of integration by "spatializing technology". As a case of study, through exploring the correlation of geographical factors and the distribution of people in the same region, theory and methods of establishing spatial distribution of population data are introduced. Through this integration, people can efficiently manage, display and analyze statistical data with existing capabilities of GIS.
