摘要: 通过对柴河林业局头道林场一块8年生的落叶松人工林优势种群的当年生的生长节律与生物量的研究发现:优势林分的当年生枝及顶枝的生长较常规林分高峰期多、高峰期持续时间长和生长量大的优点和不同;生物量的分配的研究结果也说明优势林分的树干生物量积累的比重较常规林分高,证明了该罕见优势林分速生原因的内质性,是一个难得的优良种源。

关键词: 长白落叶松, 优势种群, 生长节律

Abstract: The growth characteristics and pattern were studied in a 8-year dominant larch population in Toudao Forestry Farm, Caihe Forestry Bureau. The growth of the dominant population is higher than the normal one;It's growth pattern revealed the characteristics of more peaks, longer lasting time of the peaks and higher growth than the normal one. To sum up the research results, we conclude that the fasting growth reason are relative to the Proveance.

Key words: Larix olgensis, Dominant Population, Growth Pattern
