Progress and trend of development of restoration ecology research in the arid regions of China

In this paper, the development process and characteristics of restoration ecology research in the arid regions of China were reviewed, and the research frontiers and development trends were analyzed systemically.The study on restoration ecology in arid regions has been promoted by national demands. Revegetation was the main method and approach for ecological recovery and restoration. Future study should focus on vegetation zonal distribution, soil habitat restoration, interaction of arid land ecology and hydrology, plant water relation, biological soil crust, projection based on models and modeling, and so on. The interaction and integration of geography and biology provide a new way of thinking and approach for both theoretical and practical innovations in the development of restoration ecology.
