However, there have been argu-ments abeut advantages and disadvantage of the intercropped plantation for a long time. In this paper, proceeded from light variation in tea plantations, the influences of environmental change on the morphogenesis,net photosynthetic rate,growth,development and metabolism of tea lesves in tbe intercropped plantations as well as essential studies on tea plant ecophysiology in the last decades are summarized.

Key words: soil gas, soil respiration, soil CO₂ concentration, soil carbon decomposition.
