| 摘 要： | 为了摸清西南马遗传资源现状与特征,通过实地调查、网络分析及SPSS等数据处理得出如下结论:2006年西南马存栏291.1万匹,占全国总数40.46%,可能已经成为我国第一大生态类型马种;大理马、乌蒙马、文山马、百色马、建昌马、贵州马等西南马地方马种体尺结构由南向北、由东向西表现出逐渐偏重的趋势;西南马体尺结构紧凑,近似方形,以公马为例,体高、体长、胸围和管围分别为(115.19±7.10)cm、(114.11±8.29)cm、(132.22±9.94)cm和(15.17±1.15)cm;非密度制约因子如年无霜期、降水量、日照时数和平均气温等自然因素均与中国西南马体高呈强相关,对不同类群马的形成可能起主导作用.影响马存栏数量的影响因子主要有人均农机、人口密度、辖区比重等.
