The degradation and rehabilitation of dry valley are increasingly a focus of scientific and applied interest. This paper reviews the general conditions of eco-environmental degradation and puts forward a landscape approach for rehabilitation. Primarily, soil and vegetation degradation is the main cause of the degradation. Systematic analysis and insights into the soil and vegetation degradation phenomena...
