4. DISCUSSION
NOTE: The manuscript illustrates the response and utilization of soil moisture to rainfall under different land covers. Currently, the relationship between artificial vegetation and soil moisture comes to the critical stage, which is not only related to depletion and utilization of soil water, but also soil hydrological processes and sustainability. How to maximum use limited rainfall to replenish soil moisture and optimize vegetation types is of great guiding significance for vegetation construction, especially in arid and semiarid regions of the world.
