南宁市不同生境下5种园林灌木叶功能性状研究
Study on Leaf Functional Traits of Five Garden Shrubs under Different Habitats in Nanning City
摘要
Abstract
To explore the effects of different habitats in the city on the leaf functional traits of garden shrubs and the differ-ences in interspecific adaptability,this study took the fast ring road divider belt in Nanning and Qingxiu Mountain,as the research area,and selected five typical garden shrubs,namely,Ixora chinensis,Fagraea ceilanica,Allamanda schottii,Ficus microcarpa,and Duranta erecta as the research objects.The leaf functional traits were measured,and the plant adaptability was comprehensively evaluated by one-way analysis of variance(ANOVA),correlation analysis,and fuzzy membership function analysis.The results showed that:(1)Habitat types significantly affected the leaf functional traits of the five garden shrubs(p<0.05).In the Qingxiu Mountain habitat,SLA increased by 13.6%,and LDMC decreased by 5.1%on average compared with the fast ring road.The contents of N,P,and K in leaves increased by 4.4%,12.1%,and 12.2%,respectively.(2)The highest SLA(190.34 cm2·g-1)and leaf total N(20.56 mg·g-1)were found in the Qingxiu Mountain habitat.The contents of total K(24.74 mg·g-1)in the fast ring road leaves were significantly higher than those in other species(p<0.05).The specific leaf area was generally higher in the Qingxiu Mountain habitat,and the LDMC of Duranta erecta was the largest(0.347 g·g-1)in the fast ring road habitat.The contents of N,P,and K in leaves were significantly different due to plant species and habitats.The contents of P and K were the highest in the fast ring road habitat(0.486,24.74 mg·g-1).(3)The analysis of fuzzy member-ship function showed that Allamanda schottii had the best comprehensive adaptability,and Duranta erecta and Fagraea ceilanica were outstanding in different habitats.The results showed that the leaf functional traits of garden shrubs in different habitats were significantly different.It was suggested that the tree species with strong adaptability should be selected according to the charac-teristics of habitats,so as to provide a basis for the scientific allocation of landscaping tree species in subtropical cities.关键词
