| 摘 要： | 利用Ｐｅｎｍ ａｎ－ Ｍｏｎｔｅｉｔｈ 公式，根据叶尔羌河绿洲莎车气象站１９９３～１９９６ 年逐日气象观测资料计算了日潜在腾发量，对其变化特性进行了分析。同时建立了潜在腾发量与气温、２０ｃｍ 蒸发皿蒸发量的经验关系，根据这些经验关系进行潜在腾发量的估算方法简单，同时具有一定的精度

| Abstract: | Based on daily meteorological data from 1993 to 1996 of Shache Station in Yerqiang Oasis, daily potential evapotranspiration is calculated by Penman-Monteith equation. Characteristics of potential evapotranspiration are analyzed. Meanwhile, empirical relationship between potential evapotranspiration and air temperature and that between potential evapotranspiration and 20cm pan evaporation are established, which can be used in the estimation of potential evapotranspiration in a simple way with preferable accuracy. |
