西藏波密林芝云杉解析木分析
|
摘要
通过对西藏波密林芝云杉的树干解析,分析了优势木、平均木和被压木的树高、直径和材积生长过程。结果表明:林芝云杉生长发育过程可划分为苗木生长初期,树高速生期,直径速生期,速生后期和成熟期5个生长阶段。200 a来年平均生长为直径0.48 cm·a~(-1)、树高0.43 m·a~(-1)、材累0.051 m~3·a~(-1),由于材积速生期长达百年以上,人类干扰少,导致林芝云杉林具有极高的蓄积量。
, The height, diameter and volume of the dominant tree, the average tree and the superior tree were analyzed by studying on trunk of P. likiangensis var. linzhiensis in Bomi of Tibet. The results showed that the growth process of P. likiangensis var. linzhiensis could be divided into 5 stages which were early growing period, fast growing period of height, fast growing period of diameter, late growth period and mature period. Forest growing stock of P. likiangensis var. linzhiensis forest that was with diameter growth 0.48 cm·a~(-1), height growth 0.34 m·a~(-1), volume growth 0.051 m~3·a~(-1) in the growing period of 200 years long was very high.because of long fast growing period and little human disturbance
