我国男性青年体格状况的空间分布特征

A Study of the Spatial Distribution of Particular Characteristics in the Physique of Chinese Male Youth

目的:研究我国男青年体格指标的空间分布特征。方法:利用第三次全国应征青年体质调研数据,在ArcGIS8.1软件支持下,建立我国男青年体格指标的地理信息系统,并以此为基础采用空间局部内插分析,建立我国男青年体格指标空间分布图,以交叉评价指标为依据选择无偏最优的空间分布图。结果:分布图显示我国男青年身高、体重、胸围、Vervaeck指数分布趋势基本一致,总体上有从北向南逐渐减小或降低的趋势。除鄂尔多斯高原以外,东北、华北、西北北部以及华东地区东部的男青年的身高较高。东北、华北以及华东地区东部一带男青年的体型较粗壮;青藏高原、西南地区中部、陕西南部男青年体形较细长。结论:我国男青年体格存在明显的空间分布差异,应进一步研究不同地区不同的地理环境、气候、经济等对青少年体格状况的影响。

Methods detectable Objective To explore the spatial distribution of physique indices in Chinese male youth Spatial distribution maps of height, weight, chest-circumference, vervaeck index, rate of sturdiness, detectable rate of slimness in Chinese male youth were produced using a local spatial interpolation technique in the ArcGIS 8.1 software. Cross-validation techniques were used to evaluate the fitness of these distribution maps. Results The spatial distribution map for height, weight, chest-circumference and vervaeck index in Chinese male youth shows a consistent distribution trend, which from north to south indicate that these indices tend towards smallness. The male youth in the north-east, north China, the northern part of north-west and the eastern part of east China except the Erdos Plateau are high in height. The youth in the north-east, north China and the eastern part of east China are comparatively sturdy. Youth in the area of Tibetan plateau, median part of south-west and the southern part of Shaanxi are slim in their bodily forms. Conclusion There are significant spatial differences in the physique of Chinese male youth. Influence of geographical environment, climate and economy on adolescent physique should be studied further.
