１９８５年从辽宁省章古台引种２年生樟子松苗到秦皇岛地区．经１９９６年调查，１３年生樟子松高生长３．０２ｍ、胸径４．１７ｃｍ，与当地同龄油松高生长２．６３ｍ、胸径３．４５ｃｍ相比，长势要好，并优于北京山地及内蒙古红花尔基等地，证明秦皇岛地区引种是成功的．利用樟子松、油松针叶饲养赤松毛虫幼虫，２年生针叶饲养成活率相差４２．８％，证明樟子松对赤松毛虫的抗虫能力大于油松．对针叶成分分析的结果显示，樟子松和油松在精油萜烯、脂肪酸、酚酸含量等方面均有较大差异．
In 1985, a 2-year-old Pinus sylvestris seedlings were introduced from Zhanggutai in Liaoning Province to Qinhuangdao area. According to the survey in 1996, the 13-year-old Pinus sylvestris grow 3.02m and the diameter at breast height is 4.17cm, which is better than that of the Beijing mountain and Inner Mongolia red Hua Erji and other places, to prove the introduction of Qinhuangdao area is successful. Using Pinus sylvestris var.Mongolica and Pinus tabulaeformis, the survival rate of two-year-old needles was 42.8%, which proved that Pinus sylvestris var. Mongolica had greater resistance to Pinus thunbergii than that of Pinus tabulaeformis. The results of needle composition analysis showed that Pinus sylvestris var. Mongolica and Pinus tabulaeformis had great differences in the content of essential oil terpenes, fatty acids and phenolic acids.
