摘　　要：气候变化背景下,全球高温热浪增加导致夏季高温时间和日照强度增加,植物日灼问题加剧,但目前针对园林植物抗日灼性的研究较少。以重庆市为例,通过模拟光照试验,对重庆市8种常见园林树种的抗日灼指数、抗日灼程度、净光合速率、蒸腾速率等指标进行测定,并采用主成分分析综合评价园林树种的抗日灼能力。结果表明:可从形态指标和生理指标两方面来评价园林植物的抗日灼能力;依据抗日灼能力得分的高低,将8种树种分为3种类型,依次为抗日灼能力强(三角枫、香樟、金桂)、抗日灼能力中等(银杏、五角枫、鸡爪槭)和抗日灼能力弱(红枫、银桂)。Under the background of climate change,the increase of global high temperature and heat wave has led to the increase of high temperature time and sunshine intensity in summer,and the problem of plant sunburn has intensified.However,there are few studies on the sunburn resistance of landscape plants at present.Taking Chongqing as an example,through the simulated light experiment,the indexes of sunburn resistance index,sunburn resistance degree,net photosynthetic rate and transpiration rate of 8 popular landscape trees in Chongqing were measured,and the sunburn resistance of landscape trees was comprehensively evaluated by principal component analysis.The results showed that the sunburn resistance of landscape plants could be evaluated from the morphological and physiological indexes.According to the score of resistance to sunburn,8 species of trees were categorized into three types:strong resistance to sunburn(Acer buergerianum,Cinnamomum camphora and Osmanthus fragrans var.thunbergi),general resistance to sunburn(Ginkgo biloba,A.mono and Acer palmatum),and weak resistance to sunburn(Acer palmatum and Osmanthus fragrans‘Latifolius').
