Transpiration Rule of Pinus sylvestris var. mongolica and Its Relation to the Canopy Micrometeorology in Mu Us Sandy Area

  • Received Date: 2005-04-04
  • The transpiration rule of Pinus sylvestris var. mongolica and its relation to the canopy micrometeorology were analyzed through the experimental data of the tree sap flow and the canopy micrometeorology, which were measured by thermal dissipation sap flow velocity probe and CR10X automated meteorology system at a 10-minute recording interval respectively. The trees were 20 years old. The experiment was conducted in Mu Us sandy area during the main growing season (Apr. - Sep.) of 2004. The main results are as follows: The diurnal variations of the tree transpiration were demonstrated several-peak curve in cloudy day, but single-peak curve in the overcast day , and single-peak curve in clear day except Sep. The total transpiration of the main growing season was 1 143. 7 mm , the average daily transpiration was 6. 25 mm and monthly transpiration accounted for 10. 76% , 13. 62% , 14. 05% , 24. 56% , 19.47%,17.52% in Apr. ,May,Jun . , Jul . , Aug . , Sep . , respectively. The transpiration per tree was significantly (a=0. 01) related to the canopy solar radiation (Ra) , air temperature, relative humidity, and wind velocity in the main growing period and Ra is the most important micrometeorological factor effecting transpiration in the main growing season of the tree by comparing the partial correlation coefficient.

Abstract: The transpiration rule of Pinus sylvestris var. mongolica and its relation to the canopy micrometeorology were analyzed through the experimental data of the tree sap flow and the canopy micrometeorology, which were measured by thermal dissipation sap flow velocity probe and CR10X automated meteorology system at a 10-minute recording interval respectively. The trees were 20 years old. The experiment was conducted in Mu Us sandy area during the main growing season (Apr. - Sep.) of 2004. The main results are as follows: The diurnal variations of the tree transpiration were demonstrated several-peak curve in cloudy day, but single-peak curve in the overcast day , and single-peak curve in clear day except Sep. The total transpiration of the main growing season was 1 143. 7 mm , the average daily transpiration was 6. 25 mm and monthly transpiration accounted for 10. 76% , 13. 62% , 14. 05% , 24. 56% , 19.47%,17.52% in Apr. ,May,Jun . , Jul . , Aug . , Sep . , respectively. The transpiration per tree was significantly (a=0. 01) related to the canopy solar radiation (Ra) , air temperature, relative humidity, and wind velocity in the main growing period and Ra is the most important micrometeorological factor effecting transpiration in the main growing season of the tree by comparing the partial correlation coefficient.
