摘　　要：为了探讨不同类型油松林内群落多样性与土壤化学特性差异及其与松毛虫发生严重程度的相关性,对油松毛虫发生程度由重到轻的林分类型(油松纯林、油松落叶松混交林、油松山杏椴树混交林)内土壤的化学特性进行了比较和分析。结果表明:油松毛虫发生严重的油松纯林内的土壤肥力及各种土壤化学特性指标如土壤有机质、全N、全P、速效P、全K、速效K均低于油松毛虫发生轻微的油松混交林。In order to explore the differences in soil chemical properties of different pinus tabulaeformis forest-types and its relationship with Dendrolimus tabulaeformis in serious degree of relevance, the soil chemical properties in three different stand types of P. tabulae- formis pure forest, P. tabulaeformis-Dahurian larch mixed forest, and Apricot Tilia pine mixed forest, where D. tabulaeforrnis occurred from the heavier to lighter, were compared and analyzed. The results showed that both soil fertility and soil chemical properties in the P. tabulaeforrnis pure forest with heavier D. tabulaeformis disaster are proved to be lower than those of the P. tabulaeformis mixed forest with lighter D. tabulaeforrnis occurrence in soil organic matters, total N, all P, available P, full K,and available K.
