分析了松墨天牛（Monochamus alternatusHope）对马尾松（Pinus massonianaLamb.）林分节肢动物群落的影响。结果表明：随松墨天牛危害程度加重,马尾松林分中节肢动物的物种数和个体数明显下降,其捕食性、植食性功能群种类和个体数及寄生性天敌个体数明显减少;松墨天牛危害对灌木草本层节肢动物种类和数量影响最大,在重度危害林分中,灌木草本层的节肢动物多样性指数H′和优势集中性指数J均显著低于轻度危害林分中的指数;受松墨天牛危害后,林分中稳定性指数S1/S2和N1/N2显著下降,马尾松林分中节肢动物的多样性和稳定性及其天敌对害虫的制约潜能显著降低。

By investigation and analyzsis,this paper studied effects of Monochamus alternatus on the numeric distribution of the arthropods in Pinus massoniana forests,the results showed that the arthropods species and individuals in forests were decreased significantly with increasing M.alternatus damaging.So were the predators,herbivores and the parasitoids.All of it,the effects on arthropods in the shrub and herb layer was the most seriously,the arthropods species diversity（H′） and dominant concentration（J） in shrub and herb layer were significantly lower in severe damaged forests.After being damaged,the arthropods stability index S1/S2 and N1/N2 were decreased significantly in forests.It shows that the arthropod diversity and stability and the control potential of natural enemies to pests in P.massoniana forests were decreased significantly after being damaged.
