摘　　要：对北京市2001～2010年的气温变化情况和蛋鸡生产情况进行了调查。运用数理统计方法对调查结果进行了统计分析，结果表明：10年来北京市平均气温呈现先上升后下降趋势，基本稳定于13～13．5℃范围内，2007年平均气温达到最大值14℃；各年度月平均气温呈现正态分布，夏季7月份的平均气温最高，6月和8月次之，而冬季（12月至次年1～2月）和春初秋末（3月、11月）气温均较低，由各年度6～9月最高平均气温状况得出，北京地区气温升高的时间有所提前，气温降低的时间有所延后，使北京地区高温时间增加。自2001年以来，北京市蛋鸡养殖规模及蛋产量呈上升趋势，鸡的年平均产蛋量呈波动式变化，但整体水平在10kg以上；北京地区的蛋鸡生产变化与年平均气温变化无一次、二次相关关系（P〉0．05）。The changes in atmospheric temperature and the laying hens＇ production in Beijing from 2001 to 2010 were investigated. Meteorological data from 2001 to 2010 in Beijing were analyzed using regression and correlation methods. The results showed that the annual mean temperature appeared to be increasing firstly and then decreasing in the 10 years, ranging from 13 ℃ to 13.5 ℃. The mean temperature in 2007 reached a maximum of 14 ℃. Each year the monthly mean temperature fits the normal distribution. Mean temperature in July was the highest, followed by June and August. The temperature was the lowest in winter （from December to January or February of the next year） or at the beginning of spring or autumn （March or November）. From the mean temperature in July to September of 2001 to 2010, the number of hot day increased because maximum air temperature appears earlier and lasts longer in summer. The scale breeding and egg production in Beijing had been presenting a rising trend since 2001, and the average annual egg production was fluctuating with an overall value of above 10 kg; no correlation and quadratic correlation were detected between the egg production and the annual mean temperature in Beijing（P〉0.05）.
