In order to understand effects of brief sand-drift wind on photosynthesis and transpiration properties of Pinus sylvestris var. mongolica saplings, a field wind blowing experiment with a gradient of wind speed (0, 6, 9, 12, 15, 18 m·s-1)and sand-drift wind intensities (0.00, 1.00, 28.30, 63.28, 111.82, 172.93 g·cm-1·min-1)was conducted in June, 2013 in the Horqin Sand Land of Inner Mongolia. The results showed that: (1) brief sand-drift wind blowing had a lesser effects to diurnal variation pattern of Tr and Ci of P. sylvestris var. mongolica seedlings, but could change its diurnal variation pattern of Pn and Gs; (2) Strong sand-drift wind blowing with 15 m·s-1 and 18 m·s-1 wind speed resulted in a great decrease of the daily maximum Pn, Tr and Gs, which decreased by 22.30% and 21.98%, 22.87% and 22.31%、24.28% and 17.45%, respectively, compared to the CK; (3) with increase of sand-drift wind intensity, daily average Pn, Tr and Gs tended to decrease and daily average Ci tended to increased, which decreased by 13.26% and 11.60% in the Pn, 7.93% and 8.38% in the Tr and 1.42% and 8.54% in the Gs, increased by 9.07% and 3.22% in the Ci, respectively, in the 15 m·s-1 and 18 m·s-1 treatments compared to the CK; (4) brief sand-drift wind blowing did not resulted in significant changes to WUE of the seedlings, but resulted in a significant decrease of the light energy utilization efficiency; (5) in the sand-drift wind stress, the decrease of the Pn and Tr resulted mainly from decrease of the Gs, the decrease of the light energy utilization efficiency resulted mainly from decrease of the Pn and Gs.
