摘　　要：目的:深入了解南京市常用园林植物的固碳潜力。方法:选取南京市常见的83种乔木和灌木园林植物作为研究对象,利用植物冠层分析仪进行叶面积指数测定,计算其叶面积总量和固碳量。通过比较分析,评估各植物的固碳能力。结果:叶面积指数乔木类均值为2.41,灌木类均值为3.47。叶面积总量乔木类均值为126.68 m^(2),灌木类均值为19.89 m^(2)。固碳量乔木类植物均值为1148.47 g·d^(-1),灌木类均值为180.83 g·d^(-1),乔木类植物明显大于灌木类植物。依据固碳量对南京市常见乔灌木植物进行了聚类分析,不同种类乔灌木固碳量差异也特别显著,并推荐了固碳量较高的种类。结论:通过深入了解南京市常用园林植物的固碳潜力,可以更有效地选择植物品种、配置植被结构,从而最大限度地提升城市园林的固碳效益,为江苏低碳高效城市园林规划、设计、建设和维护管理提供科学依据和实践指导。Objective:To gain an in-depth understanding of the carbon sequestration potential of common garden plants in Nanjing City.Methods:83 common tree and shrub garden plants in Nanjing were chosen as subjects.The leaf area index(LAI)was measured by a plant canopy analyzer.The total leaf area and carbon sequestration capacity were calculated.Results:The average LAI for tree species was 2.41.And for shrubs,it was 3.47.The average total leaf area of trees was 126.68 m².Shrubs had an average of 19.89 m².Trees showed a carbon sequestration rate of 1148.47 g·d^(-1),and shrubs showed a rate of 180.83 g·d^(-1).Trees significantly outperformed shrubs in carbon sequestration.There was also a significant difference in carbon sequestration capacity among different types of trees and shrubs.A cluster analysis was conducted on common tree and shrub plants in Nanjing based on their carbon sequestration capacity.Species with higher carbon sequestration rates were recommended.Conclusion:An in-depth understanding of the carbon sequestration potential of Nanjing's common garden plants was gained.This allowed for the effective selection of plant varieties and vegetation structures to maximize carbon sequestration benefits in urban gardens.The results provided a scientific basis and practical guidance for the planning,design,construction,and maintenance management of lowcarbon and high-efficiency urban gardens in Jiangsu province.
