According to the survey data of 885 sheep farmers in NaQu and KaShi in Tibet,the researchers used the ordered model of Logit to investigate the influencing factors from the production behavior of herdsmen sheep.The result shows:it is very common for herders to enlarge the scale of the breeding.The eco-envrionmental cognition,the policy cognition,the income of families,the rate of mutton farming income,the degree of education and the relationship with villagers,have significant positive impact on the herders sheep breeding scale.Therefore,to protect the grassland,the government needs to strengthen the participation of herdsmen in grassland supervision,build up the content of the policy and the announcement of the decline of the grassland,improve the satisfaction of herdsmen policy,expand the increasing channels of herdsmen income.It can also improve the standard of livelihood while decreasing the scale of herdsmen breeding,which in turn promotes the sustainable development of grassland animal husbandry.%本文依据西藏那曲地区和日喀则市885份入户调查数据,运用有序Logit模型考察了牧民肉羊养殖规模的影响因素.研究表明:牧民扩大养殖规模较为普遍;牧民的生态环境认知、政策认知、家庭收入水平、肉羊养殖收入比重、文化程度、村民相处情况、村干部经历等对家庭控制肉羊规模有显著正向影响.对此,政府在草原保护中需要强化草原监管中牧民参与、加强政策内容与草原退化情况宣传、提高牧民政策满意度、拓展牧民增收渠道,在降低牧民肉羊养殖规模的同时提高牧民家庭生计水平,进而促进草原畜牧业可持续发展.
