, a Tertiary-era endangered plant, is of great scientific value. In this research, we focus on population dynamics in an effort to bridge the divide between micro genetic variation and a macroscopic ecological pattern of distribution. The population structure of 129 wild specimens of from eight populations was analyzed using EST-SSR molecular markers in this research. The Mantel test and RDA analysis have been used in this research to investigate the factors that influence the genetic diversity of . Using 15 pairs of SSR primers, a total of 227 alleles were detected in 129 samples from 8 populations. The mean number of alleles was 17, and the average expected heterozygosity was 0.405. It is shown that wild is divided into six individual populations. are significantly affected by wind speed in terms of the variation of genetics. It is suggested that a nature conservation area for be established as soon as possible, based on our results and the current natural distribution of the species. It is necessary to focus on the issue of pests and diseases while simultaneously preventing the continuation of anthropogenic woodcutting and disaster. Manual seedling collection should be employed in regions where the environment permits. Through making use of manual breeding techniques, this will contribute to the growth of the natural population of .
[植物名称]是一种第三纪濒危植物，具有重要的科学价值。在本研究中，我们聚焦于[植物名称]种群动态，以弥合微观遗传变异与宏观生态分布模式之间的差距。本研究使用EST-SSR分子标记分析了来自8个种群的129份[植物名称]野生样本的种群结构。本研究采用Mantel检验和RDA分析来研究影响[植物名称]遗传多样性的因素。使用15对SSR引物，在来自8个种群的129个样本中共检测到227个等位基因。等位基因的平均数为17，平均期望杂合度为0.405。结果表明，野生[植物名称]分为6个个体种群。在遗传变异方面，[植物名称]受到风速的显著影响。根据我们的研究结果和该物种目前的自然分布情况，建议尽快建立[植物名称]自然保护区。有必要在关注病虫害问题的同时，防止人为砍伐和灾害的持续发生。在环境允许的地区应采用人工采种。通过利用人工繁育技术，这将有助于[植物名称]自然种群的增长。
