| 英文摘要 | Variation in sap flow and transpiration was investigated in a 21-year-old Gansu Poplar (Populus gansuensis C. Wang and H.L. Yang) shelter-belt in the middle reaches of Heihe River Basin of northwest China during the growing season of 2003. Daily sap flow was measured by the heat-pulse velocity method on eight trees during the growing season. During the experimental period, May to September, the mean sap flow velocity on a sapwood area basis varied between 101.4 +/- 49.2 and 232.8 +/- 81.6 kg m(-2) h(-1). The transpiration rate of the Gansu Poplar shelter-belt ranged from 1.7 to 5.6 mm d(-1). On a mean daytime basis, tree conductance for water vapour transfer was between 2.1 +/- 0.7 and 13.1 +/- 4.4 turn s(-1) during the observation period. An exponential decay function, including the vapour pressure deficit, accounted for 75% of the variation in mean daytime tree conductance. (c) 2006 Elsevier B.V. All rights reserved. |
