Bursaphelenchus xylphilus Nickle is the typical pest which invading China. It causes pine wilt disease which is destructive and infectious disease. Many countries pay morn attention because of the great economic loss and the eco- environmental impacts. In this paper, the loss evaluation index system is set up, including 3 first - level indices, 24 second - level ones and 16 third- level ones. It was analyzed the loss effects and discussed the impacts on economy, ecological function, environment, and social and culture values which are caused by Bursaphelenchus xylphilus Nickle invading.
