摘　　要：在红塔山自然保护区林地内,在踏查林地基础上选取20块样地,调查松纵坑切梢小蠹有虫株数量、针叶树数量与比例、阔叶树数量与比例。结果表明:松纵坑切梢小蠹的危害率与针叶树比例成正比关系,与阔叶树比例成反比关系。因此,营造针阔混交林,降低针叶树种比例,是预防松纵坑切梢小蠹危害最有效的技术措施。Based on 20 sample plots selected by the survey for forest land in Hongtashan Nature Reserve, this paper investigated the quantity of trees damaged by Tomicus piniperda, and the quantity and proportion of coniferous trees and broad-leaved trees. On account of the proportional relationship between the proportion of coniferous trees and the damaging rate of Tomicus piniperda as well as the inversely proportional relationship between the proportion of broad-leaved trees and the damaging rate of Tomicus piniperda, this paper put forward the technical measures of constructing coniferous and broad-leaved mixed forest and reducing the proportion of coniferous trees to prevent the damage of Tomicus piniperda.
