摘　　要：目的:为制定中国中年男性红细胞压积正常参考值的统一标准提供科学依据．方法:收集了中国380个地区用温氏法(Wintrobe)测定的32475例健康中年男性红细胞压积正常参考值,运用偏相关分析和因子分析对其与海拔高度(x1),年日照时数(x2),年平均相对湿度(x3),年平均气温(x4),年降水量(x5)的关系进行了研究．结果: 5个地理影响因素值与中年男性红细胞压积正常参考值的偏相关系数分别为: r1,2345=0.651,r2,1345= -0．039,r3,1245=-0．040,r4,1235=-0．281,r5,1234=0．125．运用因子分析将5个地理影响因素综合成两个公共因子F1,F2,并用其得分值代替原始数据推导出一个回归方程: y=48 464+0．1738F1-0.4125F2±4 5％结论:海拔高度是影响中年男性红细胞压积正常参考值的最主要因素．随着海拔高度逐渐增大,中年男性红细胞压积正常参考值也逐渐增大,相关性很显著．如果知道中国某地的地理因素值,可以用公因子的回归方程来估算中国某地的中年男性红细胞压积正常参考值．依据中年男性红细胞压积正常参考值与地理因素的依赖关系把中国分为青藏区,西南区,西北区,东南区,华北区,东北区六个区．In order to supply a basis for uniting the reference value standard of Chinese middlescent men＇s hematocrit. Methods： A research is made about relationship between the reference value of 32475 examples Chinese healthy middlescent men＇s hematocrit and five geographical factors in Chinese 380 areas, which are determined by the way of Wintrobe laws. Results： It is found that altitude is the main factor affecting the reference value of Chinese middlescent men＇s hematocrit. As the altitude increases gradually, the reference value of Chinese middlescent men＇s hematocrit also increases gradually, and the partial correlation cofficient is quite obvious （r1,2345 = 0.651）. Applying the method of factor analysis and regression analysis, one regression equation is given out： y= 48.464 ＋ 0.1738F1 -0.4125F2±4.5% Conclusion： If geographical values are obtained in some areas, the reference value of Chinese middlescent men＇s hematocrit of this area can be reckoned using regression equation. Furthermore, according to the similarity of the reference value of Chinese middlescent men＇s hematocrit, taking the altitude as the main dividing basis and considering effects of other geographical factors and population distribution, China can be divided into six regions： Qingzang, Southwest, Northwest, Southeast, North and Northeast region.
