Abstract:

Based on the princilpe of hydrological balance, a new method, which is the single-tree water balance periodical measurement method, and a single-tree hydrological equation are established. The metold can be used successfully for measuring the quantities of single-tree transpiration and the forest land evaporation respectively.

Key words: The Loess Plateau, Transpiration evaporation, Measuring method of single-tree water-cycle balance, Hydrological equation of singletree, Evaporation deviation
