摘要：【目的】研究格木古树群现状及其影响因素,探讨珍稀濒危树种古树资源的保护与活化利用策略,为优化古树公园建设及管理提供技术支持,实现古树群资源保护与文化传承的协同发展。【方法】以广东省23处格木古树群为研究对象,通过对古树及林冠层大树的数量和生长性状、格木林下更新情况进行抽样调查,分析其空间分布格局、种群结构特征以及古树公园建设对天然更新的影响。【结果】在区域尺度上,格木古树群主要分布于东江流域与西江流域;局部尺度上主要保存在村落风水林等传统生态空间。林木生长指标与林分密度、胸径与树高的相关性均不显著。由于古树公园建设时间尚短,建设类型和强度对大树的影响尚未显现,但适度的古树公园建设和管理强度在短期内可促进群落更新,过度建设则严重抑制下层更新,其综合影响需要长期监测。【结论】广东省格木古树群空间分布特征和保护现状反映岭南地区的自然和历史文化特色。格木种群存在明显的自我更新抑制现象。古树公园建设是当前广东省格木古树群天然更新的重要影响因素。鉴于人为干扰的长期作用机制尚未明晰,建议实施保护优先原则下的适度利用模式,加强重点古树群的保护,降低干扰强度。
【Objective】 To study the current state of ancient Erythrophleum fordii tree groups and its influencing factors, explore the conservation and revitalization strategies for the ancient trees which are in the rare and endangered state, provide technical support for optimizing the construction and management of ancient tree parks, and achieve the coordinated development of ancient trees protection and cultural inheritance. 【Method】 Twenty-three ancient E. fordii tree groups in Guangdong Province are selected to investigate through sampling the quantities and growth characteristics of both the ancient trees and canopy-dominant trees as well as the understory regeneration. Subsequently, spatial distribution patterns, population structures, and the impact of ancient tree park establishment on natural regeneration are systematically analyzed. 【Result】 At the regional scale, the ancient E. fordii tree groups are mainly distributed in the Dongjiang River Basin and Xijiang River Basin. While at the local scale, they are predominantly preserved as geomantic forests. No significant correlations are observed between forest growth and stand density, diameter at breast height (DBH) and tree height. As the ancient tree parks have newly established, the impact of construction types and intensities on the tall trees has not yet been apparent. However, moderate construction and management intensities in the parks could temporarily promote the population regeneration;in contrast, excessive construction will severely inhibit understory regeneration. Therefore the comprehensive effects of these activities require long-term monitoring. 【Conclusion】 The spatial distribution characteristics and protection status of ancient E. fordii tree groups in Guangdong reflect the natural, historic and cultural characteristics of the Lingnan Region. The ancient E. fordii tree groups exhibit obvious self-inhibition of regeneration. The construction of ancient tree parks is the significant influencing factor to the natural regeneration of the ancient tree groups in Guangdong. As the long-term enabling mechanisms of anthropogenic interference are not clear, it is suggested that a moderate utilization model should be employed under the conservation prioritization principle to strengthen the key ancient tree groups and reduce the disturbance intensity.
