中国健康青年人红细胞压积参考值与地理因素的关系

Relationship between reference value(wintrobe) of Chinese healthyyoung people himatocrit and geographical factors

为制定中国健康青年人红细胞压积参考值（温氏法）的统一标准提供科学依据，本文研究了中国各地测定的健康青年人红细胞压积参考值（温氏法），并对其与地理最主要的因素，随着海拔高度的逐渐增大，健康青年人红细胞压积参考值（温氏法）也逐渐增大，用逐步回归分析的方法推导山了一个回归方程．如果知道了中国某地的地理因素，就可以用这个回归方程估算这个地区的健康青年人红细胞压积参考值（温氏法），依据红细胞压积参考值（温氏法）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 fro uniting the reference value(wintrobe) standard of Chinese healthy young people hematocrit, aresearch is made between the reference value(wintrobe) of Chineseyoung people hematocrit and five graphical factors, which aredetermined by the way of wintrobe lows. It is that altitude is the main factor affecting the reference value(wintrobe) of Chinese healthy young people hematorcrit also increase gradually. Applying the method of mathematical regression analysis, one regression equationare givenout. If geographical index values are obtained in some area, the reference value (wintrobe) of chinese healthy young people hematocrit of this area can be reckoned using the regression epuation. Furthermore, according to the similarity of the reference value(wintrobe) of Chinese healthy young people hematocrit, taking thealtitude, as the main dividing basis and considering effects of othergeographical factors and populationdistribution, China canbe divided into six regions:Qinghai- Xiang region, Southwestern China, Northwestern China, Southeastern China northern China and NorthearsternChina.
