  plant density
At a very high level of plant density, poor growth and even mortality can occur due to the decrease of soil water content.
      
Based on the model simulations, we determined the functional relationships among soil water content, plant coverage and slope as well as the optimal plant density on flat slopes.
      
When slope gradient was less than 10°, the optimal plant density was sensitive to slope gradient.
      
In the slope range from 10° to 30°, plant density was not sensitive to slope gradient.
