中文摘要：

随着农业信息资源呈爆炸性增长，可视化信息检索平台的研制显得日益迫切。以农业信息资源检索显示为对象，将可视化技术与搜索引擎技术相结合，主要叙述了基于元搜索的农业信息可视化中的数据处理方法和相应功能模块的设计、实现方法，还叙述了平台界面中的一些交互功能，设计实现了一个基于元搜索的农业信息可视化平台，整个系统性能稳定，能够较好地显示搜索结果。本研究不仅对农业信息检索可视化有帮助，对其它领域信息检索以及对信息检索技术本身的应用研究也具有较好的参考价值。

英文摘要：

With the explosively growing of agricultural websites, it is urgent to design a visual information retrieval platform based on meta-search. On the basis of integration of the visualization and search engines, the establishment of the platform architecture was established in the paper. The design methods of data processing and the functional modal realization for the platform were mainly described. Some interaction functions were described also. The experimen- tal operation showed its stability and advantages over traditional retrieval engines in the search results expression. It is helpful not only to the agricultural information users, but also to the information users in the other domains, and the search engine technique development and application themselves.
