摘  要:
The paper introduces the information value model,and the integration of information value method model and GIS technology. Meanwhile,the specific description of spatial prediction information value model for forest diseases and pests is made,which including four steps,the factors election,establishment of information value model and formula calculation,classification of information value resulting,the generation of comprehensive information map. Finally,the existing problems and prospects of information value model based on GIS in the field of forest diseases and pests' spatial prediction have been discussed.
