摘　　要：利用成熟的网络检索、数据库技术,结合农机推广的基础理论和方法 ,构建了基于Web的农机推广信息系统,设计了农机产品信息库,农机专家信息库,农机企业信息库和农机产品试验示范信息库等4个数据资源库。通过对各数据资源库的元数据模板设计和数据标引,建立了数据库之间的关联关系。利用自动推送技术实现了系统内部的"一站式"服务,即无论从哪一个数据库登录,根据各数据之间的相互关系,都可以查询到系统各数据库的相关信息。The information system of agricultural machinery extension includes different function modules,such as digital information collection, digital information organization, digital information service and digital information publication. Four databases have designed in the system including agricultural machinery products, agricultural machinery experts, agricultural machinery enterprises and trial demonstration in agri- cultural machinery. In this system, author empolders the metadata template for each database, designs searches strategy of system, sets up rela- tive relationships among database via the signs of data information resource and realizes one-station-style service among database. That is, whatever database you register, according to mutual relationship among data, relative data information will be found from every database.
