摘　　要：马尾松毛虫灾害与松林林分状况关系密切,松阔混交林、国外松占40%以上松林和植被覆盖度达90%以上的松林一般不发生松毛虫灾害。松林蓄积量越大,松毛虫发生面积越小。There was a close relationship between Dendrolimus punctata punctata disaster and stand status of pine forest.Generally D.punctata punctata wouldn＇t cause disaster in the mixed pine and broadleaved forests,forests with more than 40% exotic pines（Pinus taeda and P.eliottii） or more than 90% vegetation coverage.The occurrence area of D.punctata punctata decreased with the increase of stand volumn.
