摘　　要：在前人工作的基础上选用Ｐｒｉｅｔｌｅｙ和Ｔａｙｌｏｒ的湿润表面蒸发量与相对土壤湿度，对１９９２～１９９４年新疆莫索湾治沙站蒸渗仪的实测资料，用数理统计方法建立了梭梭柴林地蒸散量的估算模型，并且检验了该模型的效果。该模型只需常规气象资料和土壤湿度资料，计算简便，具有较高的精度。Based on the field data observed in the years of 1992￣1994 in Mosuowan Desert Research Station, this paper uses mathematical statistical method to establish the model for computing the evapotranspiration of Haloxylon ammodendron, refering to Priestley and Taylors potential evapotranspiration and ralative soil moisture. The result of comparing the calculated evapotranspiration with the measured evapotranspiration indicates that the model has good precision. The model needs only the general meteorological data and soil moisture data, and it can be used conveniently and suits for adoption in arid and semiarid areas.
