Abstract: We proposes a model of biodiversity information integration involving data describing biodiversity entities from different layers and angles using artificial intelligence. Based on analysis of current biodiversity database systems and the demands of biodiversity researchers, this model supports decision-making on biodiversity conservation and sustainable use. According to the Dublin Core metadata template and the standard of the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH), the model builds up a platform, in both website and CDROM forms, to publish data in different data formats (text, image, vector data, audio, and video) from distributed databases. Data exchange could be implemented smoothly among remote databases and/or between remote and local databases according to the standard of OAI-PMH.
