Vegetation restoration in China reduces deep soil moisture, impacting local water balance.
Deep soil moisture is crucial for plants in the dry Loess Plateau of China. Different types of vegetation affect deep soil moisture differently. Populus simonii forests have the highest moisture near the surface, while natural grasslands have the highest moisture deep down. Rainfall and vegetation type impact soil moisture levels. Restoring vegetation can reduce water in deep soil layers. Natural development is recommended for better vegetation stability and soil moisture balance.
