Cover Story: In arid inland areas, groundwater is the main water source to maintain vegetation growth. In the face of the over exploitation of groundwater and the gradual decline of groundwater depth, understanding the relationship between groundwater, soil and vegetation is the key to protect ecology and vegetation. In this study, an ecological survey was conducted in the lower reaches of a typical arid watershed in Northwest China. The results revealed the ecological relationship of groundwater depth–soil salinity–vegetation coverage and clarified the transformation mechanism between groundwater depth and ecological environmental problems, such as salinization and desertification, as well as defined adequate ecological protection strategies.
