| 摘 要： | Based on the meteorological data of 20 stations in the Hengduan Mountains region during 1961-2009, the annual and seasonal variation of potential evapotranspiration was analyzed in combination with the Penman-Monteith model. With the method of Spline interpolation under ArcGIS, the spatial distribution of potential evapotranspiration was presented to research the regional difference, and the correlation analysis was used to discuss the dominant factor affecting the potential evapotranspiration. The results indicated that the an-nual potential evapotranspiration showed a decreasing tendency since the 1960s, especially from the 1980s to 1990s, while it showed an increasing tendency since 2000. Regional potential evapotranspiration showed a rate of -0.17 mm a?1. Potential evapotranspiration in north, middle and south of the Hengduan Mountains exhibited decreasing trends over the studied period, and its regional trend was on the decline from southwest to northeast.

| Abstract: | Based on the meteorological data of 20 stations in the Hengduan Mountains region during 1961–2009, the annual and seasonal
variation of potential evapotranspiration was analyzed in combination with the Penman-Monteith model. With the method of Spline
interpolation under ArcGIS, the spatial distribution of potential evapotranspiration was presented to research the regional
difference, and the correlation analysis was used to discuss the dominant factor affecting the potential evapotranspiration.
The results indicated that the annual potential evapotranspiration showed a decreasing tendency since the 1960s, especially
from the 1980s to 1990s, while it showed an increasing tendency since 2000. Regional potential evapotranspiration showed a
rate of −0.17 mm a−1. Potential evapotranspiration in north, middle and south of the Hengduan Mountains exhibited decreasing trends over the studied
period, and its regional trend was on the decline from southwest to northeast. |
