摘要： 针对植物生理学教程中对蒸腾作用的指标蒸腾比率、蒸腾系数、蒸腾效率、需水量和水分利用效率的描述不尽相同，甚至是相反的问题。通过查阅国内外植物生理学相关教程，分析和讨论蒸腾作用5个指标的概念。修正和统一蒸腾比率、蒸腾系数、蒸腾效率、需水量和水分利用效率的定义。

关键词: 蒸腾比率, 蒸腾系数, 蒸腾效率, 需水量, 水分利用效率

Abstract: Aiming at the different descriptions and even opposite definitions of transpiration parameters in different plant physiology textbooks, the transpiration ratio (TR), transpiration coefficient (TC), transpiration efficiency (TE), water requirement (WR), and water use efficiency (WUE) were analyzed and discussed by referring to the different plant physiology textbooks both at home and abroad. The concepts of TR, TC, TE, WR, and WUE were further amended and unified.

Key words: transpiration ratio, transpiration coefficient, transpiration efficiency, water requirement, water use efficiency
