蒸发和蒸腾是研究近地面物质迁移规律、土壤-植物-大气连续系统过程、地面能量平衡、地表水量平衡等地面和近地面物理过程的基础,也是农田水分管理的根据.因此,对蒸发和蒸腾计算方法的研究一直受到国内外学者的高度重视.Hanks(1985)曾导出根据土壤有效水计算蒸发和蒸腾的公
Evaporation and transpiration are the basis for studying the physical processes of surface and near-surface processes, such as soil-plant-atmosphere continuous system process, ground energy balance and surface water balance, as well as the basis of farmland water management.Therefore, The calculation method has been highly valued by scholars both at home and abroad. Hanks (1985) derived the formula for calculating evaporation and transpiration based on soil available water
