Abstract: The effects of different cutting intensities in broad leaved-Korean pine forest on species,composition and incidence of forest diseases were investigated. The results showed that the number of pathogen species was reduced,but disease incidence was intensified with increasing intensity of forest cutting,The incidence indexes of three kind of typical diseases,compared with those in natural forest,were slightly increased in the forest by 30%cutting,but increased by 3.5-5. 6 times in forests by 60%cutting.There are no distinct changes in species composition and types pathogene in different cutting intensity forests.
