摘要
为制定中国老年前期男性红细胞压积参考值的统一标准提供科学依据，收集了中国各地用温氏法测定的健康老年前期红细胞压积参考值，并对其与地理因素的关系进行了研究，发现海拔高度是影响老年前期男性红细胞压积参考值最主要的因素，随着海拔高度的逐渐增加，老年前期男性红细胞压积参考值也在逐渐的增大，相关性很显著，用逐步回归分析的方法推导出了一个回归方程．如果知道了中国某地的地理因素，就可以用回归方程估算这个地区的老年前期男性红细胞压积参考值，依据老年前期男性红细胞压积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、东北区等六个区．
In order to supply a basis for uniting the reference value standard of Chinese presenile men's hematocrit,a research is made about relation between the reference value of Chinese healthy presenile men's hematocrit and five geographical factors,which are determined by the way of wintrobe laws.It is found that altitude is the main factor affecting the reference value of Chinese presenile men's hematocrit.the reference value of Chinese presenile men's hematocrit increases gradually with the rise of altitude.His obvious that with the method of mathematical regression,one regression equation is given out.If geographical values are obtained in some areas,the reference value of Chinese presenile men's hematocrit of this area can be reckoned with regression equation.Furthermore,according to the similarity of the reference value of Chinese presenile men's hematorcrit,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.
