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.
