摘要
为解决用户在信息搜索和查询中面临的低效问题,在分析现有农业地理信息特点的基础上,将时空编码引入分类编码体系中,提出了多维农业地理信息分类和编码的方案,以完整地表征农业地理信息,为现有农业信息的分类和编码方案提供新的思路,从而有益于促进我国农业的信息化和现代化。
In order to resolve the low efficiency during information research, this paper presents a new scheme--Multi-dimension Agricultural Geographical Information Classification, and spatio-temporal characteristics are imported into the code system of the classification to entirely embody agricultural geographical information. The scheme gives a new thought to current agricultural information classifications and their code systems,and is useful to accelerate chinese agricultural modernization.
