| 摘 要： | 目的：为制定中国青春期男性肺活量参考值的统一标准提供科学依据.方法：搜集了中国用肺量计法测定72个单位的213881例健康青春期男性肺活量参考值.运用相关分析的方法研究了其与海拔高度（X_1）,年日照时数（X_2）,年平均相对湿度（X_3）,年平均气温（X_4）,年降水量（X_5）,气温年较差（X_6）,年平均风速（X_7）的关系.结果：发现青春期男性肺活量参考值与地理因素之间有显著的相关关系.用偏最小二乘回归分析的方法建立了青春期男性肺活量参考值与地理因素的回归模型：Y=3024.77-0.131640X_1＋0.022388X_2＋2.381548X_3-1.344117X_4-0.030850X_5＋7.881706X_6＋39.820870X_7±557.93,并用Arcgis软件中的空间差值内插出中国青春期男性肺活量参考值的空间趋势分布图.结论：知道中国某地的地理因素,就可用此模型估算该地区青春期男性肺活量参考值,同时也可用空间趋势图直观的得到中国任何地方的青春期男性肺活量参考值.

| Abstract: | Aim:To supply a basis for uniting the normal reference value of Chinese adolescent boy's vital capacity(VC).Methods:A research is made about the relationship between the normal reference value of 213881 examples of Chinese adolescent boy's vital capacity and seven geographical factors in Chinese areas,which are determined by the spirometer method,based on partial least square regression.Results:It was found that the correlation of the reference value of Chinese adolescent boy's vital capacity and geographic... |
