摘要
利用新疆地矿局昌吉地下水均衡试验场 1 991～ 1 997年气象观测资料 ,应用修正的彭曼公式计算了新疆天山北麓平原区的日、月、年潜在蒸发量 ,分析了潜在蒸发量的年变化、季节性变化和日变化特征 ,确定了潜在蒸发量与 2 0 cm蒸发器水面蒸发量间的相关方程 ,为计算潜在蒸发量提供了
Based on meteorological data collected in Changji Groundwater Balance Test Station of Xinjiang Geological Prospecting Bureau, the daily, monthly and yearly potential evapotranspiration in plain area of northern slope of Tianshan Mountains are calculated with revised Penman formula. The change characteristics of daily, seasonal and annual potential evapotranspiration are analyzed systematically, and an experience formula of calculating potential evapotranspiration from water surface evaporation of 20 evaporation pan is given in this paper.
