Variation of module of Artemisia frigida population under different grazing intensities
冷蒿种群在不同放牧强度胁迫下构件的变化规律

The quantities of modulus of Artemisia frigida populations were sampled in the series of grazing gradient with no grazing (having been protected for twenty years by pen), mild grazing , moderate grazing , and heavy grazing in a Leymus chinensis grassland near the Inner Mongolia Grassland Ecosystem Research Station.
