摘要: 以横断山区20 个气象站1960-2009 年逐日气象数据为基础,应用1998 年FAO 修正的Penman-Monteith 模型分析了横断山区潜在蒸发量的变化,在ArcGIS 环境下通过样条插值法分析了潜在蒸发量变化的时空分异,并对影响潜在蒸发量变化的气象因素进行了讨论,结果表明:年潜在蒸发量自20 世纪60 年代中期以来呈波动减小趋势,20 世纪80 年代中期之后减小趋势更加明显,2000-2009 年呈增加趋势。潜在蒸发量的年际变化倾向率为-0.17 mm a-1,从空间分布来看,北部、中部、南部都呈减少趋势,倾向率由北向南逐渐减小。从季节来看,秋季和冬季潜在蒸发量呈增加趋势,春季和夏季呈减小趋势,春季减小趋势大于夏季,秋季增加趋势大于冬季。气温上升、风速和日照时数的降低是横断山区潜在蒸发量减少的主导因素,风速和日照时数的下降导致春季和夏季潜在蒸发量减小,气温上升导致秋季和冬季潜在蒸发量增加。
