摘　　要：为调查分析长沙市雨花区古树资源现状,采用胸径尺、树高仪、皮尺测量古树胸径、树高、冠幅,采样检测古树现状及其他定性定量指标;对古树生长指标之间,生长指标与病虫害、枯枝、黄(红)叶之间的关系,应用Spearman方法研究其相关性。结果表明:雨花区古树树高与枯枝、树高与黄(红)叶、枯枝与黄(红)叶、枯枝与病虫害呈显著正相关;冠幅与病虫害呈负相关,冠幅与胸径的相关性不明显。雨花区古树年龄结构特征基本符合长沙市整体水平,且国家三级古树资源略高于长沙市水平。In order to investigate and analyze the status of ancient tree resources in Yuhua District,Changsha City,the diameter,height,crown width and other qualitative and quantitative indicators of ancient trees were measured,and the relationship between the growth indicators of ancient trees,growth indicators,pests,dead branches,and yellow(red)leaves was studied by spearman method.The results showed that there was a significant positive correlation between ancient tree height and dead branches,tree height and yellow(red)leaves,dead branches and yellow(red)leaves,dead branches and diseases and pests,and the negative correlation between crown width and diseases and pests,and no significant correlation with DBH.The age structure characteristics of ancient trees in Yuhua District basically conforms to the overall level of Changsha City,and the tertiary ancient tree resources are slightly higher than that of Changsha City.
