英文摘要 【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.
