| 摘 要： | 采用梯度格局法沿海拔梯度设立样方,对河北承德辽河源地区天然油松林的垂直分布格局进行研究。结果表明:随着海拔的升高,油松林最大株高和海拔呈现负相关线性关系;油松林的最大胸径沿海拔梯度变化趋势不明显,呈现出先增大后减小的趋势;油松林的平均株高在海拔775~1270 m之间差异不显著,在海拔1340~1465 m之间差异不显著,只有在海拔775 m的平均株高与1340 m和1465 m的平均株高比较差异显著;油松的平均胸径随着海拔的升高差异不显著。 |

| Abstract: | We analyzed changes in species diversity of plant communities on Area Liaoheyuan using data from 10 plots,which were investigated along an altitudinal gradient.Each tree was identified and recorded.Major results were summarized as follows：Maximum height of tree decreased significantly with increasing altitude;Maximum DBH did not change significantly with increasing altitude;The mean height of trees nither change greatly between 775～1 270 m,nor between 1 340～1 465 m.The mean height of trees on the 775 m decreased sharply with an increasing altitude on the 1 340 m and 1 465 m;The mean DBH of the tree did not decreased significantly with increasing altitude. |
| Keywords: | Pinus tabulae formis vertical distributions tree height DBH diversity |
