红心杉是杉木中的优良变种,被视为杉木中的珍品,是我国南方重要的人工造林用材树种.采用树干解析方法,测定了红心杉人工林的优势木、平均木和被压木的生长过程,并用模型模拟方法对其生长过程进行了模拟.结果表明:(1)红心杉在生长过程中,最大去皮胸径连年生长量为1.92 cm·a~(-1),各级木胸径成熟期出现的先后顺序为:优势木、平均木、被压木.(2)各级木树高成熟期变化趋势与胸径相似,树高的最大连年生长量达到了1.5 m·a~(-1).(3)最大材积的连年生长量为0.017 6 m~3·a~(-1),材积的成熟期与胸径和树高的成熟期差异较大.优势木材积在第18年达最大连年生长量,成熟期在第25年;平均木材积成熟期在第24年...

Red heart Chinese fir is regarded as one of a treasure of Chinese fir variations, and it is an important species in southern China plantation. The paper used stem analysis to make the growth process of red heart Chinese fir, which divided as dominant trees (D), average trees (A) and overtopped trees (O); and used models to simulate its growing. The results shows that (1) the biggest current growth of DBH of red heart Chinese fir is 1.92 cm·a~(-1) in its growth process, and the maturation period of DBH of different classes ordered from early to...
