| Abstract: | The advance of research on the ecological characteristics and ecologial benefits were presented.The main features of shrub and its response to the environments and disturbance were expounded in ecological standpoint,which were separately presented for four shrub type,such as arid desert shrub,shrub steppe,saline-alkali shrub and secondary shrub.Subsequently the ecological benefits of shrub were discussed from five aspects,such as biological diversity,soil and water conservation, wind-shelter and sand fixtation,soil amelioration and environment cleaning.Finally the important research aspects for shrub were put forward. |
