摘　　要：对天然红松林与人工红松林大型真菌及发生的主要病害进行了调查研究。天然红松林内大型真菌为211种,林木病害主要以立木腐朽菌危害最为严重;人工红松林大型真菌种类为47种,林木病害主要以枝干和叶类病害危害最为严重。单一树种的人工红松林直接影响到大型真菌种类的减少,又形成了适合病原真菌流行的高密度和大面积的适宜寄主,从而造成侵染性病害的严重发生。这说明,真菌生物多样性是随着林内植物多样性的变化而改变的。Through the investigation in the nature and the man - made korean pine forest about the macrofungi and the variability of main pathology, in the nature korean pine forest, the macrofungi is 211 specise, and the most serious forest pathology are the root and butt rot pathology; in the manmake korean pine forest, the maerofungi is 47 species, and the main forest disease are the trunk and the leaf pathology. In the man - make kornean pine forest, for the tree species are single, this decrease the species of maerofungi , then form the high density and big area suitable host to fit to the epidemics of the forest disease, these are all make the serious oeeurenee of the infectious diseases. It shows that the biodiversity of maerofungi are change along with the lpant biodiversity variety in the forest.
