摘要：为了探讨中国天然臭柏(Juniperus sabina Ant.)生长特征的地理差异,在中国臭柏天然分布区选择14个样点开展了臭柏株高、地径、叶枝比的调查,并进行了统计分析。结果表明:1)中国臭柏的平均株高为65.11±7.12cm,平均地径为2.10±0.19cm,平均叶枝比为1.09±0.10;2)不同地区之间天然臭柏生长指标存在较显著的差异性,其中毛乌素沙地片区天然臭柏平均株高最高,新疆阿勒泰片区天然臭柏的平均地径最粗,祁连山片区天然臭柏的平均叶枝比最大;3)海拔为影响天然臭柏生长指标变化的主要地理因子,海拔与天然臭柏平均株高和平均地径之间具有显著的负相关关系,与平均叶枝比之间具有显著的正相关关系;4)臭柏天然分布区经纬度与平均株高、叶枝比间的关系不明显,但纬度与平均地径间有较明显的正相关,表明臭柏具有广阔的适生范围。
To understand the geographical differences of growth characteristics of Juniperus sabina Ant. in China,plant height,ground diameter and leaf weight /branches weight of Juniperus sabina Ant. were surveyed in fourteen different distribution areas. The results of statistical analysis showed that：（ 1） The average plant height of Juniperus sabina Ant. was 65. 11 ± 7. 12cm,the average ground diameter was 2. 10 ± 0. 19cm and the average leaf weight / branches weight of Juniperus sabina Ant. was 1. 09 ± 0. 10.（ 2） There was a difference of the growth indexes of Juniperus sabina Ant. in different regions. The average plant height of Juniperus sabina Ant. in Mu Us Sandy Land was the highest,the highest average ground diameter of Juniperus sabina Ant. present in the Aertai region,Xinjiang Province,and Qilian Mountains showd the highest average leaf weight /branches weight.（ 3） Altitude was the major influence factor of the growth indexes of Juniperus sabina Ant.,there was a significant negative correlation between altitude and average height of Juniperus sabina Ant.,and between altitude and average ground diameter of Juniperus sabina Ant.,but there was a significant positive correlation between altitude and average leaf weight /branches weight of Juniperus sabina Ant..（ 4） There was a significant positive correlation between latitude and average ground diameter; latitude had no significant influence on average height and average leaf weight /branches weight. Longitude had no significant influence on the growth indexes of Juniperus sabina Ant.
