英文摘要We assessed how climate change may impact the canopy hydrology of individualPinus eldarica,Pinus brutia, andCupressus arizonicatrees planted in arid and semi-arid climates in Iran. Precipitation that reaches the forest floor as throughfall (TF) represents a significant portion of individual precipitation events (P-g). We used a nondimensional relative sensitivity coefficient to examine the sensitivity of TF to changes inP(g). The Coupled Model Intercomparison Project phase 5 (CMIP5) HadGEM2-ES product was used under two emission scenarios (Representative Concentration Pathway (RCP) 2.6 and 8.5) to project yearly precipitation andP(g)for the measurement sites from 2020-50. There was a strong linear relationship between TF andP(g)at all sites [TF = 0.6 (P-g) - 0.2;R-2= 0.9]. The aridP. eldaricatrees showed the highest sensitivity coefficient (5.3) compared with semi-aridC. arizonicatrees (1.6). The sensitivity coefficient approximately doubled for individualP. eldaricaandC. arizonicatrees in the arid climate relative toP. brutiaandC. arizonicatrees in the semi-arid climate. This suggests that TF under trees in the arid climate were more affected by changingP(g)than in the semi-arid climate.Pinus eldaricatrees planted in the dry climate exhibited the largest sensitivity coefficient differences (3.4) between small and largeP(g). Changes in precipitation and increased smaller storm frequency are expected for arid and semi-arid regions. To buffer expected shifts in storm size due to climate change, it may be suitable to incorporate TF sensitivity when selecting trees for landscaping and urban greening.
