摘要:
 在福建省将乐林场海拔220、320 m和420 m处各设置了4块以栲树作为优势树种的20 m×30 m的样地。通过对优势树种种群结构和分布格局进行分析，结果表明，栲树幼苗储备达1 321株·hm-2，直径分布大致为倒“J”型，种群在Ⅱ、Ⅲ阶段竞争激烈，死亡率较高。将乐林场栲树种群整体上呈集群分布，不同样地面积、不同发育阶段和不同海拔高度对其分聚集强度有影响，栲树种群的聚集度随着取样面积的增大具有增强的趋势；径级增大时，栲树种群的聚集强度下降； 海拔高度增加时，栲树种群的聚集强度逐渐增强。
Abstract:
 Four sampling plots with katus as dominant tree species were set up in the altitudes of 220, 320, and 420 m each, respectively, in Jiangle Forest Farm, Fujian. Structures and distribution patterns were analyzed. The reservation of katus seedling was as high as 1 321 strains/hm2. The distribution of diameter was approximately in an upside down “J” shape. The competitions among populations were keen in Ⅱ and Ⅲ stages with higher mortality. Katus species in this forest farm generally distributed in cluster, which was affected by different scales, developmental stages, and altitudes. With the increase of sampling area, katus population concentration tended to increase. With the increase of diameter level, the population concentration decreased. From low to high altitude, katus population concentration increased.
