Abstract Based on collecting investigating datum inside and outside China, the measure methods, calculation methods, studying scale and scale transform of tree transpiration are summed up. The measure methods include rapid weighing method, whole-tree container method, lysimeter method, ventilated method, geochemical trace method, heat balance method, gas exchange method and photosynthetic system measuring method. The calculation methods include hydrological method, weather method, bowen ratio method, aerodynamic method, eddy correlation method and infrared remote sensing method. Studying scale include branches and leaves scale, individual tree scale, forest stand scale and region scale, and whose actuality and existing problems are summarized. At last, the studying direction of tree transpiration is put forward.
