Abstract

Restoration of degraded alpine meadow caused by overgrazing is directly related to
land sustainable and economical development in the Tibetan Plateau. The objective
of this study was to evaluate changes in vegetation and soil characteristics in areas
under overgrazing and exclosed for 5 to 10 years for grazing in a degraded alpine
meadow on the eastern Tibetan Plateau. Results showed that excluding livestock
grazing resulted in significant increases in vegetation coverage and plant biomass
by enhancing development of perennial grasses and sedges. Soil organic carbon
and total nitrogen in the 0–10 cm soil layer increased significantly with increasing
exclosure time. Soil clay and water contents were higher in the exclosed sites than
in the grazed site. The results suggested that the degraded alpine meadow due to
overgrazing in this region can be reversed and significant increases in soil fertility,
vegetation diversity, cover, and biomass can be achieved by implementing adequate
protecting practices.
