Abstract:: Taking Potentilla fruticosa L.，Potentilla glabra Lodd.， Sabina vulgaris Ant.，Hedysarum multijugum Maxim four ground cover plants as materials，effect of drought stress on soil moisture and the wilting coefficient，leaf free proline content，MDA content and other indicators of four ground cover plants were studied.The results showed that the appearance of drought stress early seedling had no significant changes，the state of tree growth remain strong，leaf color was normal.But the difference with the continuation of water stress，showing the changes between the different types of drought stress.Comprehensive analysis，four kinds of ground cover plant drought resistance from strong to weak order Sabina vulgaris Ant.>Potentilla fruticosa L.> Hedysarum multijugum Maxim> Potentilla glabra Lodd..
