摘　　要：为了解人类不同利用方式对山地草甸草地植物多样性的影响,课题组在新疆乌鲁木齐市南山谢家沟试验站开展了草地刈割、草地放牧和草地围封试验,分析研究了三种利用方式对山地草甸植物多样性的影响。结果表明:春季植物返青时群落高度相似,随着利用方式的改变,群落高度的变化显而易见。从物种丰富度和均匀度来看,围封方式一直处于最高水平,刈割方式其次,放牧方式最低;从多样性来看,围封和刈割方式的发展趋势相似,而与放牧的发展趋势截然相反。To understand the effects of different human utilization methods on the plant diversity of mountain meadow grassland,the research team carried out grassland mastication,grassland grazing and grassland enclosure test at Xiejiagou Experimental Station in Nanshan,Urumqi,Xinjiang,and analyzed three ways of utilization.The impact on plant diversity in mountain meadows.The results showed that the community height was similar when the plants were regreened in spring,and the effect on the height of the community was obvious with the change of utilization patterns.From the perspective of species richness and evenness,the enclosing method had been at the highest level,followed by the castration method and the lowest grazing method.From the perspective of diversity,the development trend of enclosing and mowing methods was similar,and the development trend of grazing diametrically opposed.
