摘　　要：指出了常绿阔叶树种是华北地区重要的植物造景资源,近些年随着全球气候变暖,原产于我国长江流域以南亚热带湿润地区的许多常绿阔叶树种在北方地区引种、驯化和应用,然而冬季的低温对这些常绿植物有重要影响。2016、2017年冬季洛阳出现了罕见的低温大雪天气,对植物的越冬造成了严峻的考验。基于此,探讨了冬季低温的天气状况对洛阳市常绿阔叶植物的影响,调查于2018年春季进行,采用选取样地,每木调查的方法,对各种常见常绿阔叶植物的抗低温的能力做出了评价,以期对今后这些常绿阔叶树种在洛阳的栽培管理和应用提供科学依据以及为周边其他城市引种提供参考。Evergreen broadleaf species is an important plant landscape resource in North China.In recent years,with the global climate increasing,many evergreen species,which are born in the south of the Yangtze River basin and in the subtropical humid regions of the South Asia,have been introduced,acclimated and applied in northern China.But low temperature conditions have an important effect on these evergreen broadleaf plants.In the winter of 2016 and 2017,rare cold and snowy weather appeared in Luoyang,which caused a severe test for the overwintering of plants.This papermainly discusses the influence of low temperature on the evergreen trees in winter in Luoyang.It also analyzes the cold-resistance ability of the ordinary evergreen broadleaf species in order to provide some references to their cultivation,application and introduction to the cities nearby.The research began in the spring of 2018,by way of selected area and single investigation.
