中国老年男性肺功能健康状况的地域分布规律

The geographical distribution of Chinese old men's vital capacity health status and its distribution regularity

目的 研究中国老年男性（60-75周岁）的肺活量健康状况的地域分布规律。方法 通过对老年男性肺活量实测值与区域地理因素的相关分析和线性回归分析,通过GIS空间分析实现可视化表达,精确地拟合并绘制出不同省、自治区、直辖市中国老年男性肺活量预测值的地理分布图。结果 在全国范围内,老年男性肺活量有明显的地域分布规律,由南向北,由西向东,老年男性肺活量都在逐步升高;沿海地区高于内陆,平原地区高于山地地区。结论 中国老年男性肺活量健康状况存在明显的地域分布规律,并且在全国范围内存在明显的差异性。

Objective To study the lung capacity of regional distribution of health older men（60 -75 years old）. Methods To get the visualization expression by GIS spatial analysis, and to accurately merge geographical distribution of our country＇s vital capacity prediction in older men based on the old man lung capacity measured values and the regional geography of correlation analysis and linear regression analysis. Results The lung capacity of old man had obvious regional distribution, and existed obvious differences across the country. Conclusions The lung capacity of old man has obvious regional distribution, and exists obvious differences across the country.
