摘　　要：本文通过人工模拟酸雨试验小区置木招引的研究方法,对马尾松次期性害虫进行了招引试验,并对样木中16种氨基酸含量进行了分析。结果表明,马尾松样木在人工模拟酸雨条件下比对照都易招次期性害虫的入侵,样木中氨基酸含量也比对照高。但在强酸(pH=2)条件下其氨基酸含量比对照低,其原因还有待进一步探讨。The natural attractive tests have been made in the plant stress of simulated acid rain,and sixteen of amino acids in the plant have been analysed in Hutong Ecological Research Station of Chinese Academy of Sciences in Hunan Province,The results showed that the quantity of periodic pests,such as weevils,bark beetles which attacked masson pine (Firms massoniana),in the stress of simulated acid rain,is higher than that of control condition (pH=6.8). The contents of amino acids reduced with pH value of simulated acid rain increasing in pli 3 to 6.8,but it reduced rapidly under the stress of strong acidity.
