基于GIS的土壤管理信息系统的设计与实现——以贵州省为例

本文介绍了以贵州省为例的土壤管理信息系统的开发、建立和应用.系统利用Visual Basic6.0及Map Objects2.2为开发软件;以1999年贵州省1:25万行政区划图为系统底图,建立空间数据库;以1 820组农业土壤样品、近1万多个重金属环境检测数据,建立属性数据库;按照国家土壤环境质量评价标准建立分析评价模型,获得贵州省农业土壤环境质量数据库.此外,文章还详细介绍了该系统的主要功能和应用.系统的开发应用,为进一步加强贵州省农业土壤的管理和环境质量研究,提供了基础平台和数据支持.

Design and application of Guizhou soil managing information system based on GIS

This paper introduced the design and application of Guizhou soil managing information system.The system used Visual Basic6.0 and Map Objects2.2 as its developing software;1:250000 administrative areas charts of Guizhou Province in 1999 as its base maps,which were established the spatial database;1,820 agricultural soil samples,more than 10,000 data of heavy metals to establish the attribute database.The system also established appraisal model and obtained the soil environmental quality database of Guizhou Province.In addition,the paper introduced the main functions and the application about the system in detail.The development and application of the system,not only strengthened the management and the environment quality research in agricultural soil of Guizhou Province,but also provided the foundation platform and the data support.
