| 英文摘要 | Plant transpiration plays a key role in sand-binding zones, but obtaining accurate estimates at an integrated leaf-individual-canopy scale is difficult. in this study, transpiration rates of two typical xerophytic shrubs, caragana korshinskii and artemisia ordosica, were investigated during the growing season (april-october) from 2008 to 2012 in the tengger desert, a revegetated desert area in china. gas exchange techniques, sap flow measurements, and the crop evapotranspiration minus micro-lysimeter method were used to evaluate plant transpiration. transpiration data were subsequently compared with the dynamical normalized leaf area-based extrapolation. the results indicated that at leaf level, the transpiration rates of c. korshinskii and a. ordosica were 2.67 and 4.51 mmol h2o m(-2) s(-1), respectively. the sap flow rates were 0.071 and 0.086 g h(-1) cm(-2) at the tree level, and the transpiration rates were 0.42 and 0.35 mm d(-1) at the stand level. the total seasonal transpiration of the two xerophytic shrubs reached 71.79 and 55.62 mm, representing approximately 48.4 and 37.5% of the total rainfall over this period. direct measurements of plant transpiration and upscaling transpiration from leaf level to the stand level exhibited good correspondence, which verified that leaf area was a reliable representation of scaled transpiration, especially in arid desert regions. |
