摘要: [目的] 通过对古树形态特征变异分析研究,了解古树表型性状的生态地理变异,以期为华北地区古树名木的资源保护和健康维护提供参考。[方法] 以6个区域5种不同类型的古树为研究对象,选取7个不同的形态特征指标,采用ANOVA方差分析和LSD最小显著差异法,对测定的性状特征数据进行数学统计分析。[结果] 5种古树7个性状指标间存在一定程度的变异,树洞在不同树种中的变异程度最大,而树高、胸径和树叶稀疏情况的变异程度最小,性状最为稳定;古树的形态差异与生境异质性关系密切,具有相似生境的古树通常具有相似的表型特征;树高、树叶稀疏状况和枯枝比等表型性状特征值与土壤营养元素多呈负相关关系。[结论] 华北地区古树的形态特征具有多型性,且受生境异质性影响较大,具有较好的生态适应性。

Abstract: [Objective] The objective of this study was to provide theoretical basis for ancient and famous trees maintenance in Northern China through analyzing the geographical variation base on the investigating results of the morphological characteristics.[Method] ANOVA and least significant difference (LSD) was used to analyze the variance of seven morphological characters of 5 kinds ancient trees which distributed in six sites.[Results] The results indicated that variance existed among 7 indicators of 5 species.Tree holes showed the largest degree of variance.By contrast,tree height,diameter at breast height (DBH) and leaves sparse situation showed the least degree of variance,which indicated that these traits were the most stable.Morphological characters such as tree height,leaves sparse,deadwood rate present negative correlation with the soil nutrient.[Conclusion] Morphological characteristics of ancient trees in Northern China varied and influenced by environment factors.Therefore,those ancient and famous trees could adapt easily.

Key words: ancient trees, morphological characteristics, trees height, diameter at breast height, annual length of spring shoot, leaves distribution, deadwood proportion, tree hole
