为探讨气候因素与慢性阻塞性肺部疾病（ＣＯＰＤ）发病的相关性，对全国１４个有代表性地区提供的发病与气候因素资料，进行逐步回归逼近模拟分析研究。结果表明：ＣＯＰＤ发病与气候因素关系密切。依其影响程度排序为：日温较差＞大气压力＞相对湿度＞环境温度。在选出主要影响因素并在微机上实现最佳模拟配合后可以看出：在日温较差＜７℃（绝对值），大气压力在９００～９５５ｈＰａ之间，相对湿度不低于７０％，环境温度稳定在８～１０℃，ＣＯＰＤ发病最少。
In order to explore the correlation between climatic factors and the incidence of chronic obstructive pulmonary disease (COPD), the incidence and climatic factors data provided by 14 representative areas in China were analyzed by stepwise regression modeling. The results show that: the incidence of COPD and climate factors are closely related. Sort according to their degree of influence: poor day temperature> atmospheric pressure> relative humidity> ambient temperature. After selecting the main influencing factors and implementing the best simulations on the microcomputer, it can be seen that when the daily temperature is less than 7 ℃ (absolute value), the atmospheric pressure is between 900 and 955 hPa and the relative humidity is not less than 70% Ambient temperature is stable at 8 ~ 10 ℃, the least incidence of COPD.
