摘要
收集了全国各地4417例正常人的实际碳酸氢根参考值,应用SPSS统计软件,运用相关分析和回归分析的方法,研究了实际碳酸氢根参考值与海拔高度、年日照时数、年平均气温、年平均相对湿度、年降水量5项地理因素之间的关系.结果发现,实际碳酸氢根参考值与地理因素之间有显著的相关关系(F=8.574,P=0.000).运用回归分析法对实际碳酸氢根参考值和地理因素进行多元线形回归,通过回归方程计算出全国10个城市的实际碳酸氢根参考值.依据实际碳酸氢根参考值与地理因素之间的依赖关系,将全国划分为8个区.
Objective： In order to provide scientific basis for formulating the normal reference value standards of actual bicarbonate of Chinese.Methods： The normal reference values of actual bicarbonate of 4417 Chinese were collected and studied with respect to the geographical factors,using relative and regressive analysis methods.Results： There was significant correlation between the normal reference values of actual bicarbonate and the geographical factors in China（F=8.574,P=0.000）and a regression equation,y=37.82-0. 001 488x1-0. 002 841x2-0. 067 64x3-0. 227 2xs ±4.09, was produced using the method of mathematical regression analysis. During the regression equation,y is the normal reference values of actual bicarbonate（mmol/L） ,x1 is ahitude,x2 is sunshine duration of one year（h）,x3 is average relative humidity of one year（% ） ,xs is average temperature of one year（℃ ）. Conclusion： If the geographical factors in some area in China is known, the normal reference value of actual bicarbonate in this area can be reckoned by using regression equation.
