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
Based on the daily meteorological observation data of Yarkand River Oasis, Shache Weather Station from 1993 to 1996, daily potential evapotranspiration was calculated by Penm an-Monteith formula and its variation characteristics were analyzed. At the same time, the empirical relationship between the potential evapotranspiration and the temperature and evaporation of 20 cm pan was established. The estimation method of potential evapotranspiration based on these empirical relationships is simple, and has certain accuracy
