摘　　要：运用真菌学、森林病理学与群落生态学的基本研究方法,对樟子松叶栖真菌群落结构进行了研究,共获樟子松叶栖真菌26种。叶栖真菌在小龄针叶上的种类和数量明显少于老龄针叶。上冠层的真菌种类最多,其次是下冠层,中冠层的真菌种类最少。兼性寄生性真菌在老龄针叶上的种类和数量均多于小龄针叶,并为老龄针叶的习居菌,而且随冠层的降低还有增加。An investigation was conducted to study dendrocola mycoflora of Pinus sylvestris var. mongolica needles by the basic methods of mycology, forest pathology and community ecology. A total of 26 species fungi on needles were obtained. Result showed that the species and quantities of fungi on young needles are less than those on old needles. The sequence of fungi species on needles in different crown canopies from high to low is higher canopy, lower canopy and middle canopy. The species and the quantities of facultative parasitic fungi on old needles are more than those on young needles, and increases with crown canopies from high to low.
