在中国，禁牧是恢复退化牧场的一种广泛使用的手段。然而，人们对通过禁牧令恢复退化的高山草甸所需的时间知之甚少。同时采集土壤样品，测定土壤总有机碳、微生物生物量碳、总磷和铵态氮含量。结果表明：封牧区的植物物种多样性水平和牧草质量水平均高于未封牧区。根系质量和土壤养分含量无显著差异。禁牧初期植物物种多样性和牧草质量较高，但随后呈下降趋势。根据生态系统随时间变化的动态，建议在禁牧后进行一定程度的放牧。
Banning of grazing is a widely used means of restoring degraded rangeland in China. However, little is known about the time required to restore degraded alpine meadows through the use of a grazing ban. Height and cover of individual plant species and total cover, herbage mass and root mass of each plot of a grazing ban and communal free-grazing alpine meadows in Northern Tibet were examined. Soil samples were also collected and total organic carbon, microbial biomass carbon, total phosphorus and ammonium nitrogen contents were measured. The results showed that both the level of plant species diversity and herbage mass were higher in areas of a grazing ban than in communal free-grazing land without a grazing ban. No significant differences in root mass and soil nutrient contents were observed. There was a higher plant species diversity and herbage mass in the early years of a grazing ban but there was a subsequent decline. It is suggested that some grazing after a grazing ban may be necessary according to the dynamics of ecosystem responses with time.
