中文摘要	为了解藏北地区退化高寒草地植物群落对短期围栏的响应,本研究以当地的3类高寒草地植被为研究对象,分析了围栏封育对草地群落的影响.结果表明,围栏封育措施能显著提高3类草地群落高度、盖度和地上生物量,物种数也有不同程度的增加.高寒荒漠植被群落盖度、高度变化对围封措施响应较快,但物种数变化的响应较慢; 高寒草原和高寒草甸群落盖度和高度变化对围封措施响应较慢,而物种数变化响应较快; 3类草地地上生物量变化对短期围封均表现出了较快响应.短期围栏封育对退化高寒植被群落多样性影响不显著.建议对退化高寒草甸和高寒草原可进行短期围栏与施肥相结合的草地恢复方式; 对于退化高寒荒漠草地可适当延长其围栏封育的时间,结合补播、追肥等措施,使草地植被能尽快恢复
英文摘要	An experiment was conducted to determine the response of alpine grassland communities to enclose in the northern Tibetan by monitoring the community change of three types of degraded alpine grasslands. The results of this study showed that the short-term enclose greatly increased vegetation height, cover and above-ground biomass, and the number of plant species in the three types of degraded alpine grasslands. The response of cover and height of alpine steppe and alpine meadow to the short-term enclose was slower than the response of the number of plant species of alpine steppe and alpine meadow to the short-term enclose. The short-term enclose quickly increased the above-ground biomass of the three alpine grasslands, but did not affect the plant species diversity of alpine grassland communities. This study suggested that the combination of the short-term enclose and fertilizer was the effective way to restore the degraded alpine steppes and alpine meadows and the combination of the long-term enclose and fertilizer and reseeding benefited the restoration of degraded alpine desert grassland
