| 中文摘要 | Inspired by the importance of increased temperature influence on C: N: P ratios in foliage biomass, we investigated nutrient cycles and biotic feedbacks of plants in urban heat island (UHI). Two typical ornamental plants (Buxu megistophylla Levl and Syzygium aromaticum) were chosen to study the differences of leaf element contents (C, N, P) and ecological stoichiometry characteristics, which were caused by the UHI effect. Results indicated that UHI effect had significant influences on total leaf C concentration. A range of total leaf N concentration exhibited coherence for the two plants. Total leaf N concentration significantly decreased for B. megistophylla Levl and S. aromaticum in UHI (P<0.05). However, total leaf P concentration of the two plants experienced a greatly significant decrease in UHI (P<0.001). In contrast to reference site (RS), B. megistophylla Levl and S. aromaticum in UHI both gave a relatively higher C/N ratio, C/P ratio and N/P ratio as a result of the greatly significant decrease of total leaf phosphorus content. Although UHI effect exhibited a small increase of temperature, leaf element contents as well as their stoichiometric ratio had been influenced. The influence might further disturb the relative validity of these elements, which would consequently have a potential influence on the elemental cycle of urban ecosystem. |
