摘 要:采用树干解析法试验研究了日本花柏人工林生长过程及其模拟模型。结果表明:日本花柏33年生平均木树高为12.57 m,胸径为13.26 cm,材积达0.1029 m^3;此时材积连年生长量仍然大于年平均生长量,树木生长尚没有到数量成熟阶段。日本花柏生长过程中的树高、胸径、材积与树龄之间的拟合方程分别为H=12.8278/(1+e^2.893-0.1801x)、Dbh=12.4696/(1+e^3.8388-0.268x)、V=0.126/(1+e^5.1711-0.1998x)。The individual growth process was investigated by analyzing the parse tree of Chamaeeyparispisifera and the growth models were established. The results showed that the height, diameter at breast height and volume of average tree at 33 years old were 12.57 m, 13.26 cm and 0.1029 m3 respectively. The?current annual increment of individual volume was larger than the average increment, indicated that it doesn’t reached to quantitative maturity. The individual models of average height, diameter at breast height and volume were H = 12.8278/(1+e2.893-0.1801 x), Dbh = 12.4696/(1+e3.8388-0.268 x) and V = 0.126/(1+e5.1711+0.1998 x).
