摘　　要：针对平湖市林场松材线虫病(Bursaphelenchus xylophilus)采伐迹地呈分散小块(片)状、林相上层落叶乔木保留较多等特点,以及前期更新造林中樟树单一树种纯林结构林相差的不足,选择樟科(Lauraceae)樟属(Cinnamomum)浙江樟(Cinnamomum chekiangense)、楠属(Phoebe)浙江楠(Phoebe chekiangensis)和闽楠(Phoebe bourne)、润楠属(Machilus)红楠(Machilus thunbergiii)、新木姜子属(Neolitsea)舟山新木姜子(Neolitsea sericea)等5个幼龄期喜阴、耐阴常绿树种,开展了迹地更新造林对比试验。结果表明:除闽楠外,其余4个树种表现出了较好的适应性,其中红楠、浙江楠、舟山新木姜子树形优美,在沿海迎风坡造林时表现出较强的抗风能力,耐阴性好,有一定的顶端优势,特别适用于半阴坡更新造林和林分补植等,可作为今后除治迹地更新造林的优选树种;浙江樟成林快、树体高大,早期速生性状突出,但由于林场原有樟树保留较多,可作为更新造林候选树种。Aimed at the characteristics of scattered small pieces and high retention of deciduous arbors in the upper layers of the forest in the clear-cutting forestland of Bursaphelenchus xylophilus disease in Pinghu forest farm,as well as the deficiency of the pure forest structure with single Lauraceae Species in the early reforestation,Cinnamomum chekiangense,Phoebe chekiangensis,Phoebe bourne,Machilus thunbergiii and Neolitsea sericea,five shade loving and shade tolerant evergreen tree species,including Cinnamomum chekiangense,Phoebe chekiangensis,Phoebe bourne,Machilus thunbergiii and Neolitsea sericea,were carried out a comparative experiment on afforestation in the clear-cutting forestland.The results showed that except P.bourne,the other four species showed good adaptability,among which M.thunbergiii,P.chekiangensis and N.sericea with beautiful tree shape showed strong wind resistance ability and shade tolerance when forested on coastal slope.They were especially suitable for afforestation on the semi shady slope and stand replanting,and could be used as the preferred tree species for reforestation in the future;C.chekiangense,which is tall and fast-growing in early stage,can be used as a candidate tree species for reforestation due to the reservation of original species C.camphora in the forest farm.
