松树抗风暴潮能力分析

Analysis on Storm Surge Resistant Ability of Different Pine Tree Species

在山东烟台沿海防护林中，据风暴潮过后树种的受害程度将松树分为4种类型：枯死型，濒危型，轻害型，正常型。黑松、刚松、刚火松、赤松、火炬松的受害率为10％-100％，5个树种中黑松抗风暴潮能力最强，当地种源又优于辽宁种源；刚松、刚火松次之；赤松和火炬松最差。黑松受害率低于20％，而赤松、火炬松受害率则达到了100％。方差分析表明，黑松的生长量显著高于火刚松和刚松。

The Pinus spp. trees planted in the coastal area as shelterbelts in Yantai area, Shandong Province were classified into four types i. e. withered death type, dying type, slightly damaged type and the normal type according to the damage extent after storm surge. The survey indicated that the resistant ability to storm surge of Pinus thunbergii was the best among the five pine species, whose damage rate was 10%, while the local provenances were superior to Liaoning provenance. P. rigida and P. rigida x P. taeda took the second place in terms of storm surge resistance. The storm surge resistant ability of P. densiflora and P. taeda was the weakest, whose damage rate reached 100%. The variance analysis showed that the growth of P. thunbergii was significantly higher than P. rigida x P. taeda and P. rigida.
