Further discussions were made from the perspective of native plants. Some proposals were put forward in order to provide reference for the selection and application of ornamental plants in urban green-lands of Xining city such as focusing on the diversity of ornamental plants，strengthening the development and utilization of the native plants，increasing the proportion of native plants，enriching the plant community landscape.
