The concentrations of carbon (C), nitrogen (N) and phosphorus (P), and their ecological stoichiometric ratios in plant tissues play an important role in maintaining the growth and development of plants. Although the typhoons could affect the growth and development of garden plants in coastal cities of China in many ways, the effects of typhoon on the ecological stoichiometric characteristics of carbon, nitrogen and phosphorus in urban garden plants have not been demonstrated. Therefore, the concentrations of C, N and P in leaves of common garden trees, shrubs and herbs were measured in Taizhou City, a coastal city in Zhejiang Province before one day, after one day and one week of Typhoon "Hagupit" in August 2020, respectively. Then, the short-term effects of typhoon "Hagupit" on the concentrations and stoichiometric ratios of C, N and P in these garden plant leaves were evaluated. The C/N ratio of the investigated garden trees, shrubs and herbs is 27.3±0.6, 42.9±1.4 and 25.4±2.2, respectively; the C/P ratio is 208.8±9.3, 194.1±9.6, 88.5±5.7, respectively; and the N/P ratio is 7.7±0.4, 4.9±0.2, 4.2±0.5, respectively, implying that the investigated urban garden plants are limited by N. The concentrations of C, N and P in garden plant leaves of different life forms were affected by the typhoon to varying degrees, but the concentrations of the measured bioelements gradually recovered to the original level after one week of typhoon impact. Both C and N concentrations in plant leaves were affected by typhoon followed as herb > shrub > tree, while the concentration of P in plant leaves was affected by typhoon followed as herb > tree > shrub. The differential responses of C, N and P stoichiometric ratios in garden plants to the typhoon "Hagupit" were observed among different plant life forms. The ratio of C to N in plant leaves were affected by the typhoon followed as herb > shrub > tree, the ratios of C to P in plant leaves were affected by the typhoon followed as herb > tree > shrub, and the ratio of N to P in plant leaves were affected by the typhoon followed as tree > herb > shrub, respectively. After one week of the typhoon "Hagupit", the concentrations and stoichiometric ratios of C, N and P in garden plants gradually recovered to the pre-typhoon level. In conclusion, the typhoon can have to a certain extent effects on C/N/P stoichiometry of garden plants of different life forms, and garden plants can minimize the impact of typhoon by regulating their homeostasis.
