摘　　要：[目的]随着我国畜禽遗传资源地方品种保护面临的挑战越来越严峻,加强遗传资源价值评估日益迫切。构建牛遗传资源价值评估框架,为我国地方牛品种保护和利用提供理论支撑。[方法]文章以渤海黑牛为例,采用选择实验法,将遗传资源价值划分为4个属性,利用Mixed logit模型实证测度了受访者对渤海黑牛价值属性的偏好及支付意愿,评估其遗传资源价值。[结果]受访者对遗传资源和地方品种的重要性有较高认知,主动参与品种保护和利用的意愿较强;对渤海黑牛遗传资源价值各属性的偏好显著,其中保护价值最高,其次为直接和间接利用价值,潜在利用价值最小;渤海黑牛遗传资源价值为526.07元,其中保护价值为360.17元;受访者的年龄和人均家庭收入对评估结果的影响较为显著。[结论]应建立适应中国国情的畜禽遗传资源价值评估体系,加强对牛遗传资源保护和利用政策的宣贯,加大财政资金投入力度,加快地方牛品种改良进程。As China faces increasingly severe challenges in protecting local breeds of livestock and poultry genetic resources,enhancing the assessment of the value of these genetic resources has become urgently necessary.Developing a framework for assessing the value of cattle genetic resources,so as to provide theoretical support for the conservation and utilization of local cattle breeds in China.This study took the Bohai Black cattle as a case,employed a choice experiment method,and divided the value of genetic resources into four attributes,then used the Mixed logit model to empirically measure respondents'preferences and willingness to pay for the value attributes of Bohai Black cattle.The results revealed that respondents had a strong awareness of the importance of genetic resources and local breeds,with a high willingness to actively participate in breed conservation and utilization.Preferences for the value attributes of Bohai Black cattle genetic resources were significant,with conservation value ranking highest,followed by direct and indirect use values,and potential use value being the least.The total genetic resource value of Bohai Black cattle was estimated at 526.07 yuan,with conservation value accounting for 360.17 yuan.The respondents'age and per capita household income had a significant impact on the evaluation results.Therefore,it is recommended to establish a genetic resources value assessment system suited to China's national conditions,enhance the dissemination of policies related to the conservation and utilization of cattle genetic resources,increase fiscal funding,and accelerate the improvement process of local cattle breeds.
