针对陆地表层地理空间数据的集成共享问题，提出从数据分类、数据编码到数据格网化编码的解决方案。从我国国情出发，以中国国家地理格网为基础，分析其空间数据的组织与编码体系，并针对国家科技基础条件平台-地球系统科学数据共享平台中的陆地表层数据，提出结合数据分类的数据属性编码，进而建立能够与国家地理格网相衔接的地理空间数据格网化编码应用方案。以地理空间数据的点、面实体数据为例，证实了该编码的应用可行性。预期该编码方案能够在科学数据资源管理、数据检索访问、数据资源集成、数据资源格网化处理、数据资源空间分析、数据标识与引用等方面发挥作用。

Grid is not only the special reference base, but also the container of multi sources geospatial data. This paper discussed the problem of the current geospatial data integration, which pointed out that the geographic grid was an effective method to solve the problem. According to China national situation, the national geographic grid organization and coding system was analyzed ifrstly;land surface data coding schema was designed based on the data classiifcation system of Earth System Science Data Sharing Platform;then an integration solution for land surface grid coding is proposed. Actual point and polygon data resources coding cases in Earth System Science Data Sharing Platform were experimented in the study. Results showed that the grid coding solution is feasible for geospatial integration and sharing. It can be anticipated that the grid coding of geospatial data will play important roles on data resources management, access, integration, grid processing,spatial analysis, identiifcation and citation.
