| 摘 要： | 通过对比油松刺槐混交林与油松纯林内相关因素，研究其对赤松毛虫的自然控制。结果表明：油松刺槐混交林的土壤肥力高于油松纯林，促进了油松的生长，增强了对赤松毛虫的承载能力，有利于对赤松毛虫的自然控制。

| Abstract: | The related factors in the mixed forest(mixture of Pinus tabulaeformis and Robinia pseudoacacia) and pure forest(P.tabulaeformis) were compared.The result showed that the fertility of soil in the mixed forest was higher.So the pines in the mixed forest grew better and had high tolerance towords the attack of Dendrolimus spectabilis,and thus had better natural control against the pest. |

| Keywords: | Dendrolimus spectabilis mixed pine and locust forest fertility of soil the amount of nee-dles natural control |
