Abstract

The transp iration of 24-year-old Popu lus tom en tosa. shelterbelts was investigated by Thermal Dissipationsap flow velocity Probe ( TDP) in the crop land of north China p lain from Ap ril to Sep tember in 2007. The variationof transp iration and its relationship to meteorological factorswere studied. The main results are as follows : (1) Thediurnal variations of transp iration demonstrated a single-peak curve in fine and cloudy day in the main growingseason, but in the overcast day, it demonstrated a several-peak at the main growing season. And from Ap ril toSep tember, the average velocity of transp iration per tree were 5. 44, 7. 84, 8. 05, 7. 87, 7. 26 and 7. 17 L · h-1 inthe fine days, 4. 10, 5. 87, 6. 84, 6. 68, 6. 49 and 5. 88 L·h-1 in overcast days, 4. 33, 3. 56, 4. 14, 5. 90, 3. 39 and2. 66 L·h-1 in the cloudy days。(2) The daily variations of the sheltbelt transp iration ( Tr) was characterized withthat it rose gradually in Ap ril, and reaches a peak during aboutMay, June and July, fell down was readily in Augand Sep. In the growing season ( 4—9 ) , the total Tr ( ToTr) was 488. 02 mm, and the ratios of the monthly sheltbelt transp iration to the ToTr was 11. 17% , 18. 71% , 19. 30% , 19. 29% , 16. 66% and 14. 88%. ( 3) In allmonths during the growth season of 2007, the transp iration showed significantly compound correlated with the solarradiation (Ra) , air temperature, air relative humidity and wind speed (α = 0. 01) , and Ra was the most importantmeteorological factor effecting on transp iration through comparing the partial coefficient.
