Establishment Of Expert System On Forest Diseases And Insect Pests Diagnosis And Pests Forecast

The forest diseases and insect pests are one of the most important limiting factors to the forest resources.However,almost every forestry producer is unclear to the forest diseases and insect pests, blind or not prompt preventing and controlling,leads to our forestry economy suffering the heavy loss. The talented person who masters the forestry technology is very scarce,the dissemination and application cycle of the advanced science and technology is long,and the develop speed is slow,all these have restricted the forestry production and the sustainable development seriously.In view of.the realistic situation,this research unifies the present research situations of the domestic and foreign,based on the forest diseases and insect pests as well as the Forestry informationization knowledge,recording to the actual forest diseases and insect pests diagnosis demand of our country,uses the forward and backward reasoning mechanism,carries on the research of the reasoning machine of the forest diseases and insect pests diagnosis expert system,has the very strong guiding sense to the reality.In the design for the purpose of the grass-roots farmers,the thesis mainly completed the forest diseases and insect pests recognition,the research of the knowledge expression of the forest diseases and insect pests diagnosis expert system,the design of the system reasoning machine as well as the establishment of the modules.Finally a forest diseases and insect pests diagnosis knowledge base are built for the purpose of accurate diagnosis and simple operation to the common farmers who lack professional knowledge.Using the reasonable pest forecast model will make the forecast more accurate,enhance the application capability of the system to serve the forestry producer.
