摘    要:探讨了第二代杉木人工林生物量的时空特征,运用Richards模型对杉木人工林生物量动态模拟,结果为:W=272.745(1-e^-0.126(t-1))^1/1-0.559,杉木人工林生长过程可分成4个阶段:0~5a幼林成长阶段;5~8a干材速生阶段;8~25a为成热阶段;25a后为过熟阶段。其采伐年限为25a,密度为2475株/hm^2的杉木可获得最大生物量272.745株/hm^2。

关 键 词:杉木  时空特征  Richards模型

Abstract:The paper emphatically probes into spatial-temporal characters of biomass in the secondary generation of Chinese fir plantation. The Richards model that is used to simulate plantation biomass dynamics is as follows: The growth process of Chinese fir can be divided into 4 stages: 0-5th year, the growth stage of young woods; 5-8th year, the pole stage; 8-25th year, the mature stage; after 25th year, over-mature stage. The maximum biomass can be 272.745 t/hm2 when the cutting age is 25th year and the density is 2 475 trees/ hm2.
Keywords:secondary generation of Chinese fir plantation   spatial-temporal characters   Richards Model
