人口地理信息系统建设研究

Population geographic information system construction studies

现阶段我国人口地理信息系统开发已经从初始阶段向成熟阶段过度，很多城市都独立开发了人口地理信息系统。目前开发的人口地理系统都遇到瓶颈，严重限制了人口地理信息系统功能进一步完善。研究首先对国内人口地理信息系统开发状况进行归纳，概括一般性的人口地理信息系统建设方案。然后着重讨论限制人口地理信息系统发展的两个瓶颈：使用面插值方法突破地理编码的限制，获取任意区域的人口信息，实现多年人口普查数据的统一；使用双线数据存储的方法，有效解决人口数据的更新问题，保证人口数据的现势性。

The present stage our country population geographic information system development from the preliminary stage to the mature stage excessively,very many cities all independently has already developed the population geographic information system. At present develops the population geography system all meets the bottleneck, seriously limited the population geographic information system function further to consummate. The research first carries on the induction to the domestic population geographic information system development condition,broad general population geographic information system construction plan. Then discus- ses emphatically limits the population geographic information system development two bottlenecks： The use surface interpolation method breakthrough geography code limit, the gain random region population information, realizes many year census data unification;Use double thread data storage method, effective addressing population data renewal question,guarantee population data current situation.
