In this paper, searching technology of product information based on knowledge was researched. On the aspect of cognition, we researched the relation between user\'s cognition and designer\'s cognition, explored the knowledge flow in the process of product development, set up a matching model between user\'s knowledge and designer\'s knowledge, brought forward a modeling method based on users\' cognition, and set up a measurable model of product feature; coded and decoded product form element, set up a computer aided product form design system and image evaluating system based on the result of measurement. Accordingly, the product style and product image were systematically discussed, the recognition space of product style and image was constructed, the factors that affect product style and image were put forwards and analyzed, and the relation between product image and form elements was tested by experiments. Furthermore, the product automatic recognition technologies were discussed.And then, with the media of concept model and the kernel of parameter technology, a mathematic model that describing product layout design by constraints and rules was presented. Furthermore, a product design integration system based on imagery thinking including product fonii base system based on imagery thinking, product form design system based on imagery thinking and product form intelligent design system based on space layout were set up, which tested the system and provided a new way for product innovative design.

For organizing vegetation submodel, started with the bottom-up gateway to agglomerate plot-data. The vegetation types must be confirmed before predictive vegetation mapping, therefore designed a transforming program to combine 585 plot-data from different surveys for the purpose. But the result of the classification and ordination of the combined plot-data couldn't display comprehensive vegetation types of Taiwan, because the plots were insufficient and disproportionate. Consequently, this study adopted the top-down gateway to divisive vegetation. After referring to Taiwan and east-Asia vegetation research papers and American national vegetation classification system etc., the physiognomic classification scheme of Taiwan had been drafted as vegetation submodel. The scheme included 4 levels: 2 classes, 5subclasses (subarctic, coldtemperate, cooltemperate, warmtemperate, subtropical), 8 groups (based on phenology and types of predominant leaf) and 16 formations (based on moisture regime and predominant taxa). And, the scheme dealt completely with the diverse nomenclatures of vegetation types in the past.
