Study On Expert System Of Flower Border In Harbin Area

The flower border is a kind of important flower application form. Because designers need to be well-trained to master a large amount of flower materials and esthetics techniques to design the flower border quickly. Therefore, it is difficult to design a flower border without abundant experience. We regard Harbin as region choice of plants and research the flower border expert system. The designers can make a flower border design easily and get an expert solution of the cultivation problems by asking for this system which has the mighty knowledge base and reasoning function.We make the construction and contents of the knowledge by the need analysis of the flower border design. And we investigate the ornamental plants in Harbin, then choose plants which is suitable for the flower border, observing two years' phenology characteristics, taking pictures of those plants, acquiring public knowledge of those plant materials in Harbin area, flower border designing and construction by books, magazines and networks, gathering together several experts' knowledge and experience of cultivation, flower border design and management. On such foundation, we establish a general use type knowledge base of expert system. Moreover, according to the expert's experience knowledge, we establish the reasoning rules of flower border design.This system makes use of modern relation database techniques save the knowledge of material, design, picture, cultivation etc. At the same time, we use Jess system according to CUSP to maintain the reasoning rules of design and management, and combine the background facts to carry out to reasoning work. On technique level, this system is divided into the Knowledge Base, Reasoning Engine, User Interface etc. And on the function level, the system is consist of the assistance of the flower border design and the cultivation system. The former is main system, the latter is from the system.Through two years' effort, we observe 200 hundred kinds of plants' phenology characteristics including embryotic, exhibition leaf, flower bud, beginning flower period, prosperous flower period, end flower period, fruit period, withered period. We take more than 2000 pictures and collect the domestic and international flower border pictures at the same time. We establish the material knowledge base of more than 100,000 words. It includes the material base, picture base, fountion base, construction and management base in this system knowledge base. Reasoning engine adopts the reason according to add regularly, realizing the different importance of different design factors in the process design. The user interface adopts the multi-media technique with the super conjunction technique, making the interface simple and convenient.
