摘　　要：通过暖季11个气候因子影响耗母牛日泌乳量的通径分析和回归分析,结果表明,日平均温度的升高有利于泌乳;但日极端最高温的增高对产奶的影响是负面的。相对湿度、地面最高温度对日产奶量虽然没有明显的直接作用,但它们通过极端最高温对日产奶量产生作用。The influence of eleven weather facts on daily milk yield of yak cow was analyzed by the path and linear regression analysis.The cosequences are indicated that the go upping of daily mean temperature benefit fo improving of the daily milk yield,but the influence of the extreme tallest temperature is negative on the daily milk yield,and the opposite degree of humidity,the tallest temperature of the ground measure to the daily yield although have no obvious of direct function,they produce negative function to the daily yield through the daily exetreme tallest temperature
