【摘要】 [目的]更好地了解济源市国槐古树生长现状以及古树形成所需环境条件，为古树名木的保护提供一些借鉴。[方法]对全市225株国槐古树进行了数据调查，对其空间分布、生长现状、用地类型、距离河流远近、坡向、坡度、海拔等进行了分析。[结果]济源国槐古树数量多，分布广；国槐古树在浅山区分布最多，在丘陵区长势最好；适合生长在阳坡、距离河流1 500 m以内和海拔400～<600 m;水肥和光照的差异会影响古树国槐的胸(地)围、株高和冠幅。[结论]古树的形成是各种环境因子综合影响的结果。更多还原

【Abstract】 [Objective]In order to better understand the growth status of ancient Sophora japonica trees in Jiyuan and the environmental conditions required for the formation of ancient trees, and provide some reference for the protection of ancient and famous trees.[Method]We conducted a data survey on 225 ancient Sophora japonica trees in the city, and analyzed their spatial distribution, growth status, land type, distance from the river, slope direction, slope, altitude, etc. [Result]The results showed that the number of ancient Sophora japonica trees in Jiyuan was large and widely distributed; ancient Sophora japonica trees are most widely distributed in shallow mountainous areas and grew best in hilly areas. The ancient trees of Sophora japonica in Jiyuan were suitable for growing on sunny slopes, within 1 500 m away from rivers and 400-<600 m above sea level. The differences of water, fertilizer and light would affect the chest(ground) circumference, plant height and crown width of the ancient tree Sophora japonica. [Conclusion]The formation of the ancient tree was the result of the comprehensive influence of various environmental factors.更多还原
