摘　　要：The transpiration characteristics of the tamarind artificial forest in the arid-hot valleys of Jinshajiang River, Yunnan were investigated through the measurement of the transpiration rate, stomatal conductance of tamarind leaf and the related envi- ronmental factors. The results showed that the transpiration of the tamarind in the clear sky had the close positive correlations with photosynthetically active radiation and air temperature and negative correlation with atmosphere moisture in the whole growth period. The daily change tendency of the transpiration rate was the similar with stomatal conductance, and the transpiration had the positive correlation with stomatal conductance. The transpiration rate of tamarind was highest in the rainy season of June and July and was relatively low in the drought season of March and April. The transpiration water consumption in rainy season of June and July was obviously higher than that in drought season of March and April. It fully suggested that the tamarind showed very good drought resistance and adaptability to the arid-hot valleys of Yunnan .The transpiration characteristics of the tamarind artificial forest in the arid-hot valleys of Jinshajiang River, Yunnan were investigated through the measurement of the transpiration rate, stomatal conductance of tamarind leaf and the related envi- ronmental factors.
