摘　　要：通过对乔科羊中心产区天然草地资源生态现状的调查,分析了天然草原对生态、生产、生活的影响;对2002年和2019年乔科羊品种现状进行测定分析,得出结论近20年来,乔科羊品种性能并未因天然草地质量下降而降低。对2008~2018年乔科羊种群资源现状进行统计分析,得出以下结论2008~2018十年间,前3年乔科羊存栏数开始下降,而适龄母畜比例和出栏数开始上升,2015~2018年存栏数显著下降,而适龄母畜比例和出栏数显著上升,10年中乔科羊的存栏数下降20、适龄母畜比例上升12,而出栏数上升了1倍。Based on the investigation of ecological status of natural grassland resources in Qiaoke Tibetan sheep central production area,this paper analyzed the impact of natural grassland on ecology,production and life.Based on the analysis of the current situation of Qiaoke Tibetan sheep breeds in 2002 and 2019,it is concluded that the performance of Qiaoke Tibetan sheep sheep breeds has not decreased due to the decline of natural grassland quality in recent 20 years.Based on the statistical analysis of the population resources of Qiaoke Tibetan sheep from 2008 to 2018,the following conclusions were drawn:in the first three years of 2008 to 2018,the number of Qiaoke Tibetan sheep in stock began to decline,while the proportion of female animal in season and the number of marketable fattened stock began to rise.In 2015 to 2018,the number of Qiaoke Tibetan sheep in stock decreased significantly,while the proportion of female animal in season and the number of marketable fattened stock increased significantly.In the past 10 years,the number of Qiaoke Tibetan sheep has decreased by 20%,the proportion of the female animal in season has increased by 12%,and the number of marketable fattened stock has doubled.
