摘要：植物生物量及其分配模式是全球碳循环研究的重要内容之一。为提高我国不同尺度森林生物量碳的估算和模型模拟等的准确性,该文采用标准木法研究了华北落叶松人工林典型分布区(关帝山、五台山中山和亚高山、五台山山间盆地、塞罕坝林区)的单木生物量相对生长模型、林分生物量及其分配模式的动态变化。结果表明:①林分生物量随林龄的增加而增加,但不同分布区林分生物量的生长过程存在有一定的差异。林龄较小时各区林分生物量的差别很小,但随着林龄的增加各区之间的差异逐渐变大。在五台山中山和亚高山,林分生物量在林龄25年左右时基本达到稳定,而五台山山间盆地则在林龄35年左右时才基本达到稳定,并且这两个分布区的最大林分生物量都小于关帝山和塞罕坝。②不同分布区生物量的分配模式存在一定的差异。干生物量的比例在关帝山和塞罕坝间无显著性差异(P>0.05),都明显大于五台山(P<0.05),其中五台山中山和亚高山干生物量所占的比例最小。各区枝生物量所占的比例均有显著差异(P<0.05),叶生物量所占的比例却无明显差异(P>0.05)。除五台山山间盆地外,其余3个分布区干生物量的比例与林龄、胸径和蓄积量等林分指标呈极显著正相关(P<0.01),枝和叶生物量的比例与这些指标呈极显著负相关(P<0.01),而且都以指数形式趋于稳定值,但根生物量的比例却与这些指标大多无明显相关性(P>0.05)。
To improve the precision of forest biomass C estimation and model simulation at different spatial scales, this paper examines the biomass allometry, and dynamic changes of biomass and its distribution patterns in four representative regions of Larix principis-rupprechtii plantations （Guandi Mountain, middle- and sub-alpine zones in Wutai Mountain, basins in Wutai Mountain, and Saihanba Forest Region）. Field measurements in 89 sampling plots were conducted. The results showed that： 1 ） stand biomass increased with an increase in stand age and this pattern was variable among the four regions. Differences among the four regions gradually became larger with the increase in stand age. In Wutai Mountain, stand biomass in middle- and sub-alpine zones reached stability by around age 25, while it was around 35 years old in basins. The maximum stand biomass in Wutai Mountain was less than that of Guandi Mountain and Saihanba Forest Region. 2） There were some differences in biomass distribution patterns in the four regions. No significant differences existed in the average proportion of stem biomass in total biomass between Guandi Mountain and Saihanba Forest Region （P 〉 0. 05）, while the biomass in Guandi Mountain and Saihanba Forest Region was significantly larger than that in Wutai Mountain （ P 〈 0. 05 ）. The average proportion of stem biomass in middle- and sub-alpine zones in Wutai Mountain was the smallest among the four regions. Proportion of branch biomass had significant differences among four regions （ P 〈 0. 05）, and the proportion of needle biomass had no significances among the four regions. In addition to basins in Wutai Mountain, the proportion of stem biomass had significant positive correlations to stand age, diameter at breast height, and stand volume in the other three regions （ P 〈 0.01）, the proportions of branch biomass and needle biomass had significantly negative correlations to the same three stand indices （ P 〈 0.01 ）. Both branch and leaf biomass proportions reached a stable condition following an exponential function. However, there were no significant correlations between the proportion of root biomass and most of the above three stand indices（ P 〉 0.05）.
