Abstract: The dynamic variation of transpiration and evaporation rates of 4 dwarf bamboos (Arundinaria argenteostriata, Arundinaria fortune, Shibataea chinensis, Sasaella masamuneana f.aureostriata) were measured. The results showed that the diurnal variation of transpiration rate was a double peak curve in April and August, stoma partly closed was the chief reason, however the peak time of transpiration rate of different bamboo species reach the was different. A single peak curve appeared in November and the transpiration rate of August was the highest among the tested 3 months. The correlation analysis indicated that the evaporation rate of culm and leaves significant positively correlated with temperature and illumination,and significant negatively correlated with humidity.
