摘　　要：The combined stress of drought, high temperature and excessive light characterizes the desert area. In order to survive the desert habitat, desert shrubs have evolved a number of special eco-physiological mechanisms to resist environmental stress during long-term evolution. In this paper, adaptation mechanisms of desert shrubs to environmental stress are reviewed in terms of morphological structure, water potential, photosynthesis and water use efficiency, transpiration and stomatal conductance, osmotic adjustment and anti-oxidation protection. In addition, some suggestions for future research are proposed.
