摘要
对星斗山自然保护区秃杉母树资源及人工林生物量、生长规律进行了研究 ,结果显示 :湖北省秃杉母树40株 ,其中保护区内 2 8株 ,平均胸径 82 .1cm ,平均树高 43.0 5m .16年生秃杉生物量为 75 .40kg ,各组分之间分配比例存在差异 .胸径、树高、材积平均生长量和连年生长量随年龄增加呈现规律性变化 .
This paper studies the Taiwania flousiana and the biomass and law of growth of planted forest in Xingdoushan Nature Reserve.The result shows that there are about 40 seed bearers of Taiwania flousiana in Hubei Province and there are 28 trees in Xingdonshan Nature Reserve. The average D 1.3 is 82.1cm and height(h) is 43.05 m.The biomass of Taiwania flousiana Gaussen with 16 years is 75.40 kg, and the distributive ratio is different in every component part .The average growth amount of D 1.3,H.and V. and annual growth amount change regularly with increasing ages.
