摘要
以天水市秦州区为研究区,通过对该区域古树名木资源调查数据的整理,分析了影响古树名木生长状况的环境因子;通过对坡向、坡度、坡位、海拔、土壤紧密度等环境因子成分得分系数矩阵结果的分析,得到该地区所调查古树名木环境因子与主成分之间的关系方程式。结果表明,天水市秦州区环境因子对古树名木生长状况的影响从大到小依次为:海拔、土壤紧密度、坡向、坡位、坡度。
In this paper,Qinzhou district of Tianshui city was taken as the study area and the data of ancient and famous trees resources in this area were sorted to make an analysis of the effects of environmental factors on the growth performance of the ancient and famous trees.In accordance with the component score coefficient matrix of environmental factors at slope aspect,slopeness,slope position,altitude and soil thickness,it can be concluded that the relation equation between environmental factors of ancient and famous trees investigated and main component.The effect of environmental factors in Qinzhou district of Tianshui city on growth performance of ancient and famous trees ranks as follows:altitude>soil thickness>slope aspect>slope position>slopeness.
