摘要
对大围山实验林场１６年生水杉人工林的生物量进行了测定与分析，结果表明：经过两次抚育间伐后的水杉林现存密度为１３００株／ｈｍ２，生产力为９．８７ｔ／ｈｍ２·ａ．该场水杉生长良好，具有良好的经济和生态效益．
In this paper, the biomass and productivity of a 16-year-old Metasequoia glyphotrobodes stand have been studied. The results show that after the stand was tended and thinned twice,the existing density of the stand is 1 300 tree/hm2,the productivity of the stand is 9. 87 t/hm2 ·a. The M. glyphotrododes trees in this forest farm grow very well,having fine beneficial results in economy and eco-environment.
