摘　　要：为制定中国26～45岁女性红细胞比容参考范围的统一标准提供科学依据,收集了中国330个地区用温氏法(Wintrobe)测定的24733例26～45岁健康女性红细胞比容值,并对其与地理因素的关系进行研究.结果表明:海拔高度是影响女性红细胞比容参考范围的最主要因素,用多元非线性回归分析的方法得出非线性回归模型^Y=4.291+36.618exp[0.000066(x1+sinx1)]-0.0897(x2+sinx2)±4.42.依据26～45岁女性红细胞比容参考范围与地理因素的依赖关系,把中国分成青藏区、西南区、西北区、东南区、华北区、东北区.<Abstrcat> In order to supply a reasonable basis for working out an uniform standard of the hematocrit reference values for Chinese women aged 26 to 45,the authors collected the hematocrit values(determined by Wintrobe's method)of 24733 such women,who lived in 330 areas of China. Then a study was made on the relationship between hematocrit values and geographical factors.It showed that the altitude was the key factor affecting the hematocrit reference values for feminie.Thus a nonlinear regression model was presented by multivariate regression equation as follows:Y=4.291+36.618 exp-0.0897(x_2+sinx_2)±4.42.Further,according to the relationship between the hematocrit reference values(for women aged 26 to 45)and geographical factors,China could be divided into six areas,ie.Qingzang area,southwest China,northwest China,southeast China,north China,northeast China.
