中文摘要	为了探讨植被、家畜增重和载畜率的关系,在内蒙古四子王旗短花针茅荒漠草原开展了4种载畜率处理,分别为:对照(0羊hm~2/a)、低载畜率(0.91羊hm~2/a)、中载畜率(1.82羊hm~2/a)和高载畜率(2.71羊hm~2/a)的随机区组试验,每个处理3个重复。结果表明:(1)植物群落的盖度、高度、密度、地上现存量随着载畜率的增加出现了显著降低的趋势(P<0.05)。(2)载畜率增加使得丰富度指数显著降低(P<0.05),虽然低载畜率处理下的香浓维纳指数显著高于中载畜率和高载畜率处理组,但与对照处理组相比没有差异(3)中载畜率处理时家畜的公顷增重达到最大,而个体增重随着载畜率的增加而减小。
英文摘要	In order to explore the relationship between livestock body weight and vegetation characteristics, different grazing intensities were carried out in the Stipa breviflora desert steppe.A random block design was used in the experimental area including 4 different stocking rates zero stocking rate(0),light stocking rate(0.91),moderate stocking rate(1.82)and high stocking rate(2.71))and 3 repetitions for each treatment.The results showed in following contents.Firstly,the vegetation coverage,height,density and aboveground biomass exhibited a significant decreased trend duo to the increase of stocking rate (P<0.05).Secondly,the increase of stocking rate significantly reduced the richness index(P<0.05). The Shannon Wiener index in light stocking rate was significantly higher than that of the moderate stocking rate and high stocking rate.However,the Shannon Wiener index was similar between the light stocking rate and zero stocking rate.Thirdly,The livestock body weight gain per hectare reached maximum in moderate stocking rate,and the individual body weight gain decreased with the increase of stocking rates.
