摘要
为更有效地推进易县的古树资源保护工作,对易县的古树资源特征及分布进行调查分析。结果表明:易县现有古树909株,包括14科21属28种,其中优势科为松科、柿科、柏科,优势属为松属、柿属、侧柏属,优势种为油松、柿、侧柏。从分布格局来看,易县909株古树皆分布在乡村、山间等非核心区域,清西陵管委会是古树分布较为集中的区域,优势种为油松。易县大部分古树(791株)立地条件优良,99株古树生长环境较好,19株古树立地条件差;生长势为正常株的古树有894株,衰弱株14株。从古树保护现状来看,易县在古树保护方面存在一定不足,仅有8株古树设置防护栏杆,12株古树建有专用树池,3株古树采取人工支撑措施。通过对易县古树资源进行深入分析,总结了易县古树保护过程中存在问题,并提出解决建议,为提高易县古树资源保护工作成效提供参考依据。
To effectively promote the protection of ancient tree resources in Yi County,an investigation and analysis were conducted on the characteristics and spatial distribution of ancient tree resources in Yi County.The results showed that there are 909 ancient trees in Yi County,belonging to 28 species in 21 genera of 14 families,with the dominant families being Pinaceae,Ebenaceae,and Cupressaceae,the dominant genera being Pinus,Diospyros,and Platycladus,and the dominant species being Pinus tabuliformis,Diospyros kaki,and Platycladus orientalis.In terms of distribution,all 909 ancient trees in Yi County are located in non-core areas such as villages and mountains.The Qingxiling Management Committee is an area with a relatively concentrated distribution of ancient trees,with the dominant species being Pinus tabuliformis.Most of the ancient trees in Yi County(791 trees)have excellent site conditions,99 trees have a good growth environment,and 19 trees have poor site conditions.There are 894 normal trees and 14 weak trees in terms of growth potential.From the perspective of the current status of ancient tree protection,Yi County has some deficiencies in the protection of ancient trees,with only 8 ancient trees equipped with protective barriers,12 ancient trees having dedicated tree pools,and 3 ancient trees adopting artificial support measures.Through an in-depth analysis of the ancient tree resources in Yi County,the problems in the process of ancient tree protection in Yi County were summarized,and suggestions were provided to provide a reference for improving the effectiveness of the protection of ancient tree resources in Yi County.
