摘要
在内蒙古鄂尔多斯市鄂托克前旗绒山羊增绒示范区进行限时放牧对草原利用的影响研究表明,限时放牧区与自由放牧区相比,植被平均高度增加5cm左右,盖度提高12%左右,密度增加40株/m2,地上生物量增加20%～40%。
The studies on the effects of limiting time on the utilization of grassland in the thickening demonstration region of cashmere goat in Ordos City of Inner Mongolia showed that the average height of vegetation in the limiting time grazing region increased 5 cm, the coverage increased 12%,the density increased 40 plants/m2 and the overground biomass increased by 20%-40%, compared with that in freedom grazing region.
