Impacts of grazing on the system coupling between vegetation and soil in the alpine and subalpine meadows of Wutai Mountain
放牧对五台山高山、亚高山草甸植被-土壤系统耦合的影响

The subalpine and alpine meadow vegetation of Wutai Mountain,distributed in altitude from about 2400m a.s.l.through to 306 1m a.s.l.at the summit,serves as the largest summer mountainous pasture for cattle grazing around the local area in Northern China.The degradation of meadow with different grades owing to overgrazing in different extents has been observed in both vegetation and soil.Considering some features of vegetation,i.e.,the coverage,the aboveground biomass,the ratio of annual to biennial plants i...
