根据越西、小金、平武、峨眉山、成都实测的1951~2000 年的气象资料和地理参数,用Penman-Monteith公式计算蒸发蒸腾量,研究ET0 与地理参数之间的规律. 结果表明:3~8月份,ET0 随纬度的增高逐渐增大,在31纬度处于最高;8月份之后,低纬度ET0 逐渐高于高纬度ET0 ,且随时间延续,差距逐渐拉大,纬度为28.39 时,ET0 最高. 在424.2 和506.1 m海拔高度下ET0 逐月变化规律基本相同,且均在7月份达到最大值;随着海拔的增高,在中海拔地区的876.5和1 659 m两处ET0 的变化规律与低海拔地区相似,但变化过程呈现一定的前移趋势;高海拔地区2 369.2 m变化曲线进一步前移,最大值与中低海拔地区相差较小.

According to the meteorological data and geographical parameters in 1951-2000 , calcu-lating crop the evapotranspiration ( ET0 ) for Penman -Monteith model.The research ET0 between the geographic parametersand geographic regularity .Results show:March to August , increases with increasing latitude , the latitude in the highest 31;after August , gradually lower latitudes above the high latitudes , and with passage of time , gradually widening the gap between the latitude of 28.39 , the highest.424.2 m, 506.1 m altitude monthly variation under basically the same , and reached a maximum in July;with the increase of altitude , in the altitude of 876.5m, 1659m variation of two low-altitude areas with similar but the change process presents certain forward trends;high altitude 2369.2 m further forward curve , the maximum and the low altitude difference is small .
