[Method]According to Hunan climate properties and the functions of herbaceous ground cover plants, previous research results and experts'' opinions were consulted, and then 14 items relative to plant growth situation, ornamental value and stress resistance of 6 species of ground cover plants introduced to Hunan were put into the corresponding weight through the description of 5 ranks from good to bad and 5 score system was set to obtain assessed criterion and comprehensively e valuate the 6 kinds of new introduced plants. [Result]The plant height of Carex ''Evergold'' was the shortest but its spread ability was the strongest. The ornamental effect of Dianthus Superbus was the best. The resistance ability of Alternanthera Paronychioides was the strongest. The order of comprehensive weighted score of 14 indexes for 6 species of introduced ground cover plants was Carex ''Evergold''>Altemanthera Paronychioides>Tulbaghia violacea>Dianthus Superbus>Imperata cylindrical ''Rubra''>Verbena bonariensis.
