摘　　要：利用1958—2009年间西藏那曲地区牦牛的统计资料,分析了那曲地区牦牛数量变化的特征和规律。结果表明,那曲地区牦牛数量占畜群比例的19%～29%,牦牛数量占畜群比例总体呈下降趋势;畜种群结构的调整已经达到"发展牦牛(含黄牛)、适度发展山羊、减少绵羊、控制马"的总体原则,为那曲地区畜牧业的良性发展奠定了基础。Using statistics of yaks in Naqu Prefecture of Tibet Autonomous Region between 1958 and 2009, characteristics and laws of quantity change of Naqu yaks were analyzed.
