Abstract: In order to provide scientific basic data for analyzing degree of responding the environmental factors, analyzing optimum condition of physiological ecology and improving productivity, photosynthetic rate, transpiration rate and the environmental factors of Hippophae rhamnoides L. were measured by the open exchange system, LI-6400 Portable Photosynthesis System in the west of Inner Mongolia. The results showed: Photosynthetic rate and transpiration rate had daily and seasonal variation, the photosynthetic rate monthly average from May to September was 9.46 μmol/ (m2·s), and transpiration rate monthly average was 6.66 mmol/ (m2·s); The photosynthetic rate, transpiration rate have significant correlation with environmental factors (temperature, relative humidity, photosynthetic active radiation).

Key words: Hippophae rhamnoides L, Photosynthetic characteristics, Transpiration characteristics
