Abstract
With Corylus avellana,Vitex negundo and Lespedeza floribunda as the experimental materials,the physiological properties were tested and analyzed under water stress conditions.The principal drought-resistant physiological indexes of tree species include leafwater-holding,chlorothyll content,MDA content and prolin content. Drought resistance were evaluated by using the formula of vague mathematical jurisdiction,and the drought-resistent ability of three bush species was Vitex negundoLespedeza floribundaCorylus avellana.
