摘要:利用优势木高生长与密度关系相对较小,并且是立地和年龄的函数这一特性以及直径生长的多因子效应等生物学规律,将优势高作为独立变量引入其它相关模型构建了杉木人工林收获模型系统。解决了杉木人工林自然生长和伐后生长模拟,建立了标准树高曲线和直径与断面积相容性预估模型以及间伐模拟系统,推导出了由于间伐而引起的非生长性增长的计算公式。
By using the biological law that height growth of dominant tree is inde-pendent of its
plantation density and it′s a function of the site an stand age and that diametergrowth can
indicate a multifactor effect,and by the use of taking the dominant height as anindependent
variant and introducing it into other related models,a yield modelling system forChinese fir
plantation has been constructed.It helps to provide a growth modelling fornatural growth and
post-thinning growth of Chinese fir plantation. It can help to build astandard tree height curve,a
compatible predicting model for diameter and cross-sectionalarea and a thinning modelling
system.In addition,a mathematical equation on the nongrowthincrease caused by thinning can
be deduced.
