中文摘要	在内蒙古鄂尔多斯市西部红沙、无芒隐子草草原化荒漠草地上,选择了不同放牧强度的5个牧户,研究了自然放牧条件下暖季不同放牧强度对牧草产量和山羊体重的影响.结果表明:(1)放牧强度与牧草现存量呈负相关关系,回归方程式为y=-4.0643X+42.563(R~2=0.8819).(2)放牧强度小于0.61只羊/hm~2时,草地净生长量与对照区无显著差异(p＞0.05),表现为等补偿性生长;放牧强度大于0.61只羊/hm~2时,草地净生长量与对照区有显著性差异(p＜0.05),表现为欠补偿性生长.(3)山羊个体增重随着放牧强度的加重而下降,回归方程式y=-1.212X+9.622(R~2=0.9502).(4)山羊单位面积增重随着放牧强度的加重先增加后降低.
英文摘要	The experiment was conducted in steppe desert in western of Erdes in Inner Mongolia. During the experiment, 5 plots in different grazing intensities were selected to study the effect of different grazing intensities on herbage yield and liveweight of goat. The result showed as following : ①There was negative correlation between grazing intensity and herbage yield, and the regress equation is Y=-40643X+42.563(R~2=0.8819) ② There was no notable difference (p>0.05) between net growth production in grazing land and in control plot, and plants showed equal compensatory growth, while the grazing intensity is lower than 0.61 sheep per hm~2.However,the notable difference (p<0.05) between net growth production in grazing land and in control plot appeared,and plants showed undercompensatory growth, when the grazing intensity is higher than 0.61 sheep per hm~2.③Increases in goats liveweightgradually declined with increasing grazing intensities,and the regress equation is Y=-1.212X+9.622 (R~2=0.9502)④Increases in goats liveweight per hm~2 first increased and then decreased.
