摘  要:
对老君山自然保护区乔木层生物量动态进行了测定和研究。结果表明,乔木层总生物量为195.17 t·hm-2,其中日本落叶松的生物量为93.87 t·hm-2,占乔木层总生物量的48.10%;其他主要树种锐齿槲栎、华山松、白桦和其它硬阔类分别占25.45%、19.83%、3.97%和2.66%。乔木层生物量随着林分胸径的增长,各器官具有不同的增长速度,到林分发育成熟时,日本落叶松、锐齿槲栎和华山松总生物量和各器官生物量都相继达到最大值,而白桦和其它硬阔类则在林分发育中期逐渐消亡,到林分发育中后期,总生物量趋于稳定。

摘  要:
Dynamics of tree layer biomass in the Laojun Mountain Nature Reserve were determined and studied. The results showed that the tree layer biomass was 195. 17 t·hm-2,the biomass of Japanese larch was 93. 87 t·hm-2,accounting for 48. 10% of the total biomass of tree layer; other major species of Sharpteeth Oak,Huashan pine,birch and the other hardwood category accounted for 25. 45%,19. 83%,3. 97% and 2. 66%. Arbor layer biomass with DBH growth and various organs with different growth rate,to the maturation of the forest,Japanese larch,Sharpteeth Oak and Huashan pine biomass of total biomass and biomass of different parts reached a maximum value,and birch and the other hard broadleaf was in stand development medium gradually dying out. At the late stage of stand development,the total biomass tended to be stable.
