摘　　要：调查发现,习水国家级自然保护区三岔河管理区内的福建柏(Fokienia hodginsii)呈集群分布,主要生于海拔1000m以上温暖湿润的山地森林中,各样地福建柏植株平均密度为400株/hm2,覆盖度达46.2%,形成以华山松(Pinus armandii)、福建柏为主的常绿针叶林和针阔混交林,各样地福建柏个体数量波动较大,标准差为9.13。研究区福建柏种群总体为不完全、衰退型种群,特别是幼树幼苗严重缺失使其成为一种不连续种群。It was found that Fokienia hodginsii in Shachahe district of Xishui National Nature Reserve were of clump distribution,mainly located in warm moist mountain forests over 1000 m above sea level with the formation of evergreen coniferous forests or coniferous broad-leaved forests dominated by Pinusarmandii and Fokienia hodginsii.The average density of Fokienia hodginsii plants in the sample plots was 400/hm2,and the coverage was 46. 2%,The number of individuals of Fokienia hodginsii in each sample area varied greatly,with a standard deviation of 9.13. The population of Fokienia hodginsii in the study area was generally incomplete and declining,especially the young tree seedlings were seriously missing,making it a discontinuous population.
