| 摘要 | Transpiration, an essential component of surface evapotranspiration, is particularly important in the research of surface evapotranspiration in arid areas. The paper inverted the transpiration of non-irrigated Haloxylon ammodendron and its spectral responses at the canopy scale in the southern edge of the Gurbantunggut desert in Xinjiang, China. The results are as follows: The stem sap flow rate appeared biomadal or multi-peak course and maintained a certain flow in the night. The stem sap flow maintained at 0 ∼ 0.1 L/h, with a peak appearing at 12:00 ∼ 17:30, 0.316 L/h. "Noon peak" appeared from mid May to early September, at 14:00 ∼ 16:00. For monthly changes, the peak value appeared in June, with the value varying (0.32 ± 0.20) L / h, followed by July (0.30±0.16) L/h, then, May and August, the minimum value appeared in September (0.15±0.03) L/h. At the canopy scale, the optimal exponential model of the sap flow rate based on the hyperspectrum is y = 0.0015e3.8922x, R2 = 0.806. © 2012 SPIE. |
