Abstract [Background] Chinese fir is a common afforestation tree species in southern China. Under the background of climate change, droughts frequently occur. Studying the water transfer process of forest trees under special weather conditions can provide a basis for predicting the characteristics of transpiration water consumption in future scenarios.[Methods] We used the Granier thermal diffusion sap flow probe (TDP) to observe the sap flow of Chinese fir from March to July, and the soil moisture dynamics were measured by the AZS-100TDR, the meteorological factors such as the solar radiation, air temperature, relative air humidity, and rainfall were simultaneously observed. The saturation index curve was used to respectively fit the sap flow density, solar radiation and air vapor pressure deficit to analyze the influence of the sap flow characteristics of different provenances of Chinese fir in Dagangshan on the meteorological factors and the response of soil moisture dynamics. [Results] 1) The diurnal changes of sap flow of different Chinese fir provenances showed obvious changes in day and night with solar radiation and air vapor pressure deficit, and the difference was significant (P<0.01). Among them, the sap flow density of the provenance from Jiangxi Tonggu was the highest. The peak sap flow density during the period of sufficient soil moisture (RSP) was higher than that during the period of soil moisture deficit (RDP). The provenance from Xiushui, Jiangxi had the smallest change in sap flow density under the two moisture conditions with the lowest sap flow density, which is suitable to plant in poor moisture conditions. 2) The fitting equations of sap flow density of different provenances to meteorological factors in the two periods showed that the rate of increase of sap flow density in the RSP period was higher than that in the RDP period. The main factor affecting sap flow during the RSP was vapor pressure deficit, and solar radiation in RDP. [Conclusions] Soil moisture conditions, meteorological factors, and provenance origin will all affect the sap flow density of fir tree trunks, and different provenances have different sensitivities to different factors. This study reveals the drought resistance characteristics of different provenances and the response mechanism to drought, aiming to provide a scientific basis for the sustainable management of fir plantations and the effective management of forest water resources in different regions of southern China.
