| 摘 要： | 在内蒙古短花针茅荒漠草原采用5个载畜率水平绵羊放牧试验,研究植物群落对载畜率的响应.研究结果表明,主要植物盖度、高度和密度在低载畜率和中等载畜率下保持较高水平;中等载畜率有利于短花针茅生长;随着载畜率的增加,植物群落现存量下降;短花针茅草原适宜的载畜率为1.7～2只羊/hm2/半年.

| Abstract: | The plant community characteristics under 5 stocking rates were measured in shee p grazing system of Stipa breviflora desert steppe in Inner Mongolia, the re sults showed that there were higher coverage, height, and density of main plant species in low and middle stocking rates than that in heavy stocking rate ; middle stocking rate was benefit to the growth of Stipa breviflora; the standing crop of plant community declined with the increase of stocking rate, and the proper stocking rate was 1.7～2 sheep/hm2/half year in Stipa breviflora desert steppe. |
