AB  - A defoliation experiment was conducted on a <I>Leymus chinensis</I>-dominated 
  steppe to provide guidelines of grazing management and restoration of degraded 
  grasslands. There were five defoliation treatments: CK (non-defoliation as control); 
  LD (Light Defoliation, cut 12 cm aboveground level); MD (Medium Defoliation, 
  8 cm); HD (Hard Defoliation, 4 cm) and SD (Severe Defoliation, 2 cm). Results 
  showed that HD and SD defoliation significantly decreased the belowground biomass. 
  Defoliation increased plant species diversity but decreased biomass of <I>L. 
  chinensis</I> significantly. The biomass of <I>L. chinensis</I> under LD was 
  lower than that in control indicating <I>L. chinensis</I> was highly sensitive 
  to defoliation. It is necessary in this area that grazing should be restricted 
  to a level of light defoliation to prevent loss of plant productivity.
