Abstract


Forest Pests and diseases are causing serious harm to forest resources is one important factor , grassroots farmers lack the knowledge on pest and disease diagnosis , prevention or control is not timely blind , will cause economic losses. Our lack of forest pest management professionals , if not in time for the grass-roots farmers to provide services , will severely restrict forestry production and sustainable development. For reality , this study combines research on the basis of the status quo at home and abroad , combined with forest pests and forestry related areas of information technology knowledge , the diagnosis for the actual needs of forest pests , using a combination of forward and backward reasoning mechanism for forest pests diagnostic expert system inference engine research, has a strong practical significance. The spirit of grassroots-oriented foresters design purposes, mainly to complete this forest pest identification , pest and disease diagnosis expert system of knowledge representation system inference engine design and function modules design and implementation work . Ultimately successful design of forest pest diagnostic knowledge base , the establishment of a practical , standardized forest pest diagnosis and pest forecasting expert system . To make a more accurate diagnosis of pests and diseases , the diagnostic process is more easy to operate, lack of expertise to meet the needs of ordinary farmers . Meanwhile, the use of reasonable pest forecasting model that makes pest forecasting work more accurate. Further improve the diagnosis of forest pests and pest forecasting systems applications, and bring forest pests and pest forecasting diagnostic expert system to better serve the grassroots farmers .
