| Abstract: | Using method of the space sequence instead of time sequence,characteristics of grazing resistance of dominance species in degraded grassland in the eastern part of Qilian mountain were studied.Those dominant plants were Melica przewalskyi,Heteropappus altaicu,Kobresia pygmaca.The results showed that: grazing disturbance influenced the plant growth including the numbers of bunches(or tillers),shoot branching,and the shoot branching in every bunch(or tiller).The subdominant species which belongs to the same d... |
