Abstract To study relationship between plant gas exchange parameters and environmental factors, Ceratoides latens (C3) and Calligonum roborovskii (C4) were taken as the research object. The purpose of our research was as follows: (1) to analyse the diurnal variation characteristics of photosynthesis rate, transpiration rate and stamatol conductance, as well as their responses to altitude elevation, (2) to compartmentalize adjustment types of photosynthetic "noon-break", (3) to detect the seasonal variation of photosynthetic rate and transpiration rate, as well as their response to altitude elevating, and (4) to compare the size order of plant water use efficiency and leaves’ δ13C value. Result showed: (1) The higher the altitude was, the more the photosynthetic rate of Calligonum roborovskii was, monthly variation of photosynthetic rate and transpiration rate of Calligonum roborovskii were not significant, while the response of diurnal and monthly variation of Ceratoides latens to different altitude was not so significant as Calligonum roborovskii; (2) Photosynthetic rate "noon-break" of Calligonum roborovskii and C.latens was caused by assimilation decline of enzyme system, while not by "stamatol limitation factors"; (3) Photosynthetic rate and transpiration rate of Calligonum roborovskii were significantly affected by photosynthetic active radiation (PARi) and CO2 concentration, and the association of photosynthetic rate and transpiration rate of Ceratoides latens with environmental factors was not significant; and (4) improvement of water condition was the main factor that promote Calligonum roborovskii migrating to higher altitude, and temperature increase helps the Calligonum roborovskii to grow well.
