Abstract: This paper deals with the relation between light respiration rate and illumination, temperature, as well as the relation between dark respiration rate and temperature for Aneurolepidium chinense under two soil water conditions. The result shows that the relationship between light respiration rate and light intensity is a nonlinear function. Light respiration rate increases quickly with increasing light intensity when light intensity is lower, while at higher lightr intensity, the rate increases much slowly. When the temperature is lower than high temperature compensation point of photosynthesis for A. chinense, light respiration rate increases with the increasing temperature within limits; when temperature reaches a certain limit, the rate decreases and then increases once again. Dark respiration rate increases with increasing temperature and increasing velocity of the rate accelerates with the increase of temperature within limits. When the soil becomes dry, light respiration rate decreases markedly and dark respiration rate decreases slightly.
