摘　　要：以红松不同栖息地的树栖真菌分离率作为种群个体参数．采用多样性指数和均匀性指数对树栖真菌 进行多样性比较。结果表明：树栖真菌多样性和均匀度越高．病害发生的可能性越低．呈负相关。isolating rates of dendrocola fungi on different habitats of Korean pine were used as individual parameter. and diversity indices and evenness indices were adopted to carry on diversity comparison. The results show that the species diversity indices and the evenness indices of dendrocola fungi negatively correlate to the probability and degree of disease occurrence. The more the indices of diversity and evenness, the less the probability and degree of disease occurrence,
