摘要
以内蒙古锡林郭勒草原西乌珠穆沁旗家庭牧场为研究对象,采用跟踪测试方法,全面记录家庭牧场的草地利用情况、植被状况和畜群数量变化等,并对资源进行优化配置。研究结果表明:家庭牧场试验户植物地上生物现存量高于对照户;家畜体重变化随植物地上生物量的增长逐渐增加,随植物地上生物量的降低而下降;根据家畜体重及草场植物地上生物量对畜群结构进行调整(减少家庭牧场家畜数量、增加饲草料量),使草畜趋于平衡,家庭牧场资源得到优化配置。
Taking the family ranch of west Ujimqin Banner in Xilingol Grassland of Inner Mongolia as the research object,the tracking test method was adopted to comprehensively record the grassland utilization,vegetation status and the change of the number of livestock in the family ranch,and optimize the allocation of resources.The results showed that the aboveground biomass in the experimental households were higher than those in the control ranch.The body weight of livestock increased with the increase of aboveground biomass,but decreased with the decrease of aboveground biomass.According to the weight of livestock and the aboveground biomass,the structure of livestock was adjusted(reducing the number of livestock in family ranch and increasing the amount of forage feed),so that the grass and livestock could be balanced and the resources of family ranch could be optimized.
