In this paper, the soil moisture, plant height, the relative conductance of Chrysanthemum leucanthemum, Coreopsis, ＇North American yellow＇ Beijing summer Chrysanthemum, Beijing miniature Chrysanthemum, proline content and soluble sugar content of physiological and biochemical indicators of four ground cover plants of Compositae were determined, and the drought resistance was studied. On the basis of all indexes, four different varieties of drought-resistant between the ability have significant differences that Composite indicators, the ability of the resistance to drought from strong action to the weak is Beijing miniature Chrysanthemum, ＇North American yellow＇ Beijing Summer Chrysanthemum, Coreopsis, Chrysanthemum leucanthemum
