本文研究了中国吉林省长白山区阔叶红松林倒木贮量的动态变化规律。阔叶红松林倒木贮量包括其现有倒木及其年输入量等贮量的变化规律。阔叶红松林现有倒木贮量开始为16.25 t·hm-2,以后随时间减少,到100年分解掉其干重的85%左右,300年后所剩无几。倒木年输入量平均约为0.6 t·hm-2,其贮量是随时间而增加,200年后稳定在31 t·hm-2,可保持到该群落的顶级时期。倒木总贮量的变化在初期呈增加趋势,而后随着现有倒木的完全分解,倒木贮量就与其倒木的年输入趋于一致,最后稳定在上述水平上。图4表2参9。
In this paper, the dynamic changes of the quantity of down-piled-wood in the Korean pine forest were studied in Changbai Mountain, Jilin Province, China. The deciduous broad-leaved Korean pine forest reserves include its existing inverted wood and its annual input and other reserves changes. The existing inverted woodland reserves of broad-leaved Korean pine forests began to be 16.25 t · hm-2, and then decreased with time. After 100 years, 85% of its dry weight was decomposed, leaving little after 300 years. The average annual input of inverted wood was about 0.6 t · hm-2. Its storage capacity increased with time and stabilized at 31 t · hm-2 after 200 years, maintaining the top stage of the community. The change of total stock of inverted wood showed an increasing trend in the initial stage. Then, with the complete decomposition of the existing fallen wood, the amount of inverted wood stored was consistent with the annual input of the fallen wood, and finally stabilized at the above level.
