As one of the common garden shrub species in Beijing, Jasminum nudiflorum is very popular among citizens for its unique ornamental properties in early spring. Copper (Cu) pollution is one of the most serious heavy metal pollution types in Beijing. To explore the remediation effect of J. nudiflorum on urban copper pollution. By simulating the soil and atmospheric copper pollution conditions in Beijing, pot experiments were conducted to set up nine different concentrations of soil and atmosphere Cu treatments to verify the Cu enrichment ability and physiological growth characteristics of J. nudiflorum. The results were as follows: (1) Soil treatment and atmospheric deposition treatment and were able to significantly increase Cu content in root, stem and leaf of J. nudiflorum, among them, the contribution of soil ranged from 63.48% to 96.99%. The Cu content in each treatment showed the order of root>stem>leaf. (2) Under atmospheric treatment, photochemical conversion efficiency (Fv/Fm) and relative chlorophyll c
