摘要：古树名木的监测、管理、保护一直是研究的重点,相关学者也开展了大量的研究并取得一定的成果,但是对影响其生长状况相关因子的研究还较少。以浙江省古樟树为研究对象,通过分析调查数据,运用相关分析、主成分分析等方法,确定树高、胸径、冠幅3个衡量古樟树生长状况的指标,并研究其与坡度、坡向、坡位、海拔、土层厚度5个环境因子之间的关系。结果表明:对古樟树生长状况指示作用大小为:冠幅>胸径>树高,其中胸径、树高与环境因子之间呈现显著相关性,而冠幅与环境因子之间不存在显著相关性;海拔是影响古樟树生长状况的主要环境因子,海拔与胸径之间呈现显著的负相关,与树高之间呈现显著的正相关;坡度与树高之间呈现显著的负相关;土层厚度与胸径之间呈现显著的正相关;坡向、坡位与古樟树生长指标之间不存在显著的相关性。
The ancient and famous trees’ monitoring, management and protection have been the focus of the study. The relevant scholars have carried out lots of researches and got some results, but the research of related factors affecting the growth status of ancient and famous trees is also less. By taking ancientCinnamomum camphorain Zhejiang Province as an example, through the analysis of the survey data, by using correlation analysis and principal component analysis, three measurable indicators of ancient C.camphora growth conditions （tree height, diameter and crown） were surveyed. And the relationship amongifve environmental factors （slopeness, slope aspect, slope position, altitude, soil thickness） were investigated. The results show that the indicative functions to ancient C. camphoragrowth status ranked from big to small as gollows： crown width〉 DBH（diameter atbreast height）＆gt; tree height. There were signiifcant correlations between DBH, tree height and environmental factors, while no signiifcant correlations between crown width and environmental factors; Altitude was the major environmental factor affecting ancient C. camphora growth status, there was a signiifcant negative correlation between altitude and DBH, a significant positive correlation between altitude and tree height; there existed a signiifcant negative correlation between slopeness and tree height; there was a signiifcant positive correlation between soil thickness and DBH; slope aspect, slope position had no signiifcant correlations with the ancientC. camphora growth indexes.
