| 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...

| Abstract: | 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 slow... |
