Based on the resource investigation and introduction in the early stage, the regional test of 4 wild cover plants of Potentilla fruticosa L., Potentilla glabra Lodd., Hedrysarum multijugum and Sabina vulgar screened in 4 different regions in Qinghai area with high ornamental function and strong resistance were done, in order to accurate positioning of these 4 varieties. The results showed that 4 species of ground cover plants in 5 regions performanced good. The growth rate were negatively correlated with altitude, annual accumulated temperature was positively correlated with. The higher altitudes, annual accumulated temperature was lower, the annual growth of more small; the lower the altitude, annual accumulated temperature was higher, the greater the amount of annual growth. At an altitude of less than 3 740 km, the mean annual temperature was higher than 0.7℃, ≥10℃ accumulated temperature of not lower than 103.86℃ in the normal growth, and its ornamental was reflected.
