中文摘要：

为了给中国人血液标准碳酸氢根参考值的制定提供科学依据，收集了全国各地12803例正常人标准碳酸氢根参考值，运用相关分析和回归分析的方法，发现标准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、年降水量等5项地理因素之间有很显著的相关性。运用SPSS软件中剔除变量法（remove）对标准碳酸氢根参考值和地理因素之间进行多元线性回归，推导出方程p=21．84＋0．1515 x3-0．0008300x5±1．04。Y是标准碳酸氢根参考值（mmol／L），x3是年平均气温（℃），x5代表年降水量（mm），1．04是剩余标准差；利用该方程，推算出全国1288个县市的标准碳酸氢根；运用空间插值的原理，在AreGtS9．0环境下进行空间插值，绘制出中国人标准碳酸氢根参考值分布图。由此，可以根据某地的年平均气温、年降水量，通过回归方程计算或者通过查阅中国人标准碳酸氢根分布图，获得该地的标准碳酸氢根参考值。

英文摘要：

To reveal the geography distributing regularity of normal reference value of Chinese Standards bicarbonate and provide scientific basis for making its unified standards, this paper has collected 12 803 cases of normal reference value of Standards bicarbonate throughout China. In the application of the method of related analysis and regression analysis, it is found that the correlation of geographical factors （altitude, annual sunshine duration, average annual temperature, annual average relative humidity, annual precipitation） and the Chinese normal reference value of standards bicarbonate are quite significant. In the application of the method of remove in SPSS software, multiple linear regressions between normal reference value of Chinese standards bicarbonate and geographical factors, one regression equation is inferred： Y=21. 842 41 ＋0. 151 51x3-0. 000 83.1;5 ＋ 1. 040 3. In the above equation , 1） is normal reference value of Chinese standards bicarbonate（ mmol/L）, x3 is Average annual temperature（ ℃ ） ,x5 is Annual precipitation（ mm）, 1. 040 3 is the value of the residual standard deviations. 1288 observation points of normal reference value of Chinese standards bicarbonate have been calculated in China by using this equation. The normal reference value of Chinese standards bicarbonate distribution map has been made by using spatial analysis of GIS . If Chinese standards bicarbonate is wanted to know in some certain area, the normal reference value of Chinese standards bicarbonate of this area can be reckoned by using the regression equations or the inspection map.
