家畜品种的遗传多样性在畜牧业生产中起着重要的作用，但品种的大量流失正威胁着家畜遗传资源的遗传多样性。采用了Weitzman方法，该方法被接受为评估AngR遗传多样性的框架。应用Weitzman方法对我国12个肉用山羊品种的遗传参数进行优先保护排序。根据中国12个肉用山羊品种的11个微卫星标记数据，计算了总遗传多样性、各品种对总多样性的贡献率、边际多样性、保育潜力等遗传多样性度量指标。12个山羊品种的期望多样性为7132个，占总遗传多样性的50.03%。12个品种的平均灭绝概率为0.375，其中海南黑山羊的灭绝概率最高，其次是藏山羊、海门山羊和贵州白山羊。海南黑山羊的边际多样性最高(-0.312)，福清最低(-0.189)。海南黑山羊对总体遗传多样性的相对贡献率最大，其次是麻关山羊、宜昌白山羊和西藏山羊。从灭绝趋势来看，12个品种的保护重点依次为海南黑山羊、西藏山羊、贵州白山羊、马关山羊、成都麻羊、海门山羊、建昌黑山羊、安徽白山羊、福清山羊、宜昌白山羊、山南白山羊、马头山羊。Weitzman方法是生物多样性资源保护的一种新思路，为物种保护和相关政策的决策提供了参考。以期为我国肉用山羊品种保护提供客观合理的标准和策略。
The genetic diversity of livestock breeds plays an important role in livestock production, but the significant loss of breeds is threatening genetic diversity of farm animal genetic resources (AnGR). The Weitzman approach which was accepted as a framework for assessment of genetic diversity on AnGR was exploited. In this study, Weitzman method was applied to set the priority of conservation b y using genetic parameters of 12 Chinese meat goat breeds. Several measurement indexes of genetic diversity, involving total genetic diversity, contributions of each breed to the total diversity, marginal diversities, conservation potential, were calculate d based on 11 microsatellite marker data of 12 Chinese meat goat breeds. The expected diversity of 12 goat breeds was 7132 which was 50.03% of the total genetic diversity. The mean extinction probability of 12 breeds was 0.375, where Hainan black goat was the highest, followed by Tibet goat, Haimen goat and Guizhou white goat. The marginal diversity of Hainan black goat in all breeds was the highest (-0.312), Fuqing goat was the lowest (-0.189). Hainan black goat had the greatest relative contribution to ov erall genetic diversity, followed by Maguan goat, Yichang white goat and Tibet goat. According to the trend of extinction, the conservation priorities of 12 breeds were Hainan black goat, Tibet goat, Guizhou white goat, Maguan goat, Chengdu ma goat, Haimen goat, Jianchang black goat, Anhui white goat, Fuqing goat, Yichang white goat, Shannan white goat and Matou goat. The Weitzman approach is a new idea to biodiversity resources protection, which is a reference for breed conservation and the decision-making of the relevant policy. We hope to provide objective and rational criteria and strategy for decision-making in conservation of Chinese meat goat breeds.
