The paper studies the drought resistance and performance of five ground covers(Sedum lineare, Sedum lineare 'Pu Fu ', Sedum elatinoides, Zephyranthes Candida, Ophiopogon japonicus)under drought-stress through the testing of artificial climatic cabinet. We choose soil moisture content, relative water content of leaves, relative electric conductivity, chlorophyll, SOD, malondialdehyde (MDA), proline (Pro), etc, to be the indexes of adaptability. Based on the related analysis of data, which came from both detection and observation, we carry on the comprehensive evaluation on the five ground covers by using the subordinative function method. The results indicate that their drought resistance in the order from strong to weak is Z. candida>S. elatinoide> S.lineare> S. lineare 'Pu Fu' > O. japonicus.
