摘要
利用Mapinfo7.0中文版软件和Visual Basic 6.0高级程序设计语言开发出湖南省烟区平衡施肥的地理信息系统。该系统通过Mapinfo的内置关系型数据库和Access数据库建立了主产县空间数据库、土壤属性数据库、气象数据库和烟草营养试验数据库,可进行数据的输入与输出、更新与查询、统计、养分图制作与输出等功能,且根据不同地块或区域的养分指标等影响因子给出施肥卡。
Mapinfo 7.0 and Visual Basic 6.0 were used to exploit GIS for balanced fertilization of tobacco in Hunan Province. Spatial database, soil property database, meteorological database and tobacco nutrient test database in major production counties were established by Mapinfo and Access.
