“…X. Wang et al, 2007Foggin, 2008). Consequently, this reduces the role of alpine grasslands in soil and water protection (Wen et al, 2010;Brandt et al, 2013;You et al, 2014). Such grazing-induced degradation of alpine grasslands was observed in the early 2000s (Q. L. Wang et al, 1997;Liu et al, 2008;Wang et al, 2009;Harris, 2010;Lin et al, 2013a, b), mainly because livestock number increased from approximately 0.8 × 10 8 in 1997 to 1.08 × 10 8 sheep units in 2011 on the Tibetan Plateau (Yang, 2002;He et al, 2008;Sun, 2012).…”

“…The ecosystem quality of alpine grassland is usually indicated by biodiversity, plant height and density, vegetation cover and plant productivity; generally, higher indexes signify a good ecosystem [23,24]. Most of these indexes, however, can be replaced by carbon content.…”

“…In this study, it was calculated by the weighted comprehensive assessment of vegetation cover, aboveground biomass and plant height of grasslands in the study area. Taking the grassland comprehensive evaluation index (Li and Liu, 2004) and grassland degradation index (Gao et al, 2006;Wen et al, 2010) as references, we selected three most representative factors (i.e. aboveground biomass, plant height and vegetation cover) to establish the grassland evaluation index (Eq.…”
