摘 要:目的:探讨自然环境因素对少数民族学生生长发育及其20年变化的影响。方法:应用因子分析方法确定身高、体重、胸围3项指标的权重系数,计算出23个少数民族18岁男、女学生生长发育水平的发育分,并将发育分与自然环境因素进行20年变化的相关性分析。结果:1)20年来,少数民族18岁青年发育分的变化与气候因素的变化相关性不密切;2)1985年和2005年少数民族18岁青年发育分北方地区大于南方地区;发育分与地球纬度、年日照时数、气温年较差呈中度以上显著正相关,与其他气候因素也有相关性;发育分与气候因素逐步回归分析首选因素,男生为年降水量和年日照时数,女生为年日照时数和气温年较差。结论:自然环境因素是影响少数民族青年生长发育的一个不可忽视的因素,但20年气候因素的变化对生长发育变化的影响不重要。Objective:To study the natural environment factors on minority young people’s growth and influence on the twenty year’s change. Method:Using factor analysis to determine the weighted coefficient of body height, weight and chest circumference, calculate the growth and development scores of 23 minority young people aged at 18 and analyze the correlations of 20 year’s change between growth score and environmental factor. Results:1)The correlation of change between growth scores and the climate for minority young people with age of 18 is not close.2)The growth scores of young people with age of 18 from the northern are higher than that from the southern between 1985 and 2005 .The growth score and most climatic factors are all significantly correlated and the correlation coefficients between the growth score and geographical latitude, sunshine duration, mean annual range of temperature are above the range of middle and direct proportion.Stepwise analyzing the first factor between the growth score and climatic factors, the male student is rainfall and sunshine duration while female student is sunshine duration and mean annual range of temperature. Conclusion:The result shows that the natural environmental factor is a unique factor that affects minority young people, but it is not an important factor for the growth change.
