| 摘 要： | 应用TWINSPAN、CCA和物种多样性分析,从植物群落、植物种与环境的生态关系等方面研究了东灵山华北落叶松人工林的植被分布格局,并给予合理的环境解释。TWINSPAN分类将华北落叶松人工林分为4个类型,分类结果在CCA二维排序图上得到了较好的验证。样方与物种的CCA排序较好地揭示了该区华北落叶松人工林的分布格局与环境梯度的关系：坡位、坡度、土壤厚度和海拔是影响该区华北落叶松人工林的主导因子。结合物种多样性分析,结果表明东灵山绝大多数华北落叶松人工林生长良好,并根据华北落叶松喜凉湿习性,建议在该区自然分布海拔以下造林时,应优先选择阴坡和半阴坡的中、下位坡。 |

| Abstract: | Based on a survey of 36 community quadrats,we examined the relationship between species composition of a Larix principis-rupprechtii plantation forest and environmental factors in Dongling Mountain using TWINSPAN,CCA,and species diversity analysis.The plantation communities were classified into four groups by TWINSPAN,and the results were validated by CCA.The distribution pattern of vegetation reflected a strong influence from the environments.The results of CCA clearly reflected the relationships between the pattern of plantation communities and environmental gradients.Our results showed that position,slope,soil thickness and altitude of communities were the dominant factors affecting the pattern of the L.principis-rupprechtii plantation in Dongling Mountain,and the majority of the plantation grew well.Based on the habitat preference of L.principis-rupprechtii for a cool and moist environment,we suggest that artificial afforestation of L.principis-rupprechtii should be based on its ecological characteristics. |
