【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。
[Abstract]:Objective: to explore the effect of natural environment on the growth and development of ethnic minority students. Methods: the weight coefficients of three indexes, height, weight and chest circumference, were determined by factor analysis, and the developmental scores of 18 years old male and female students of 23 ethnic minorities were calculated. The correlation between the development score and the natural environment factors was analyzed in 20 years. Results: in the past 20 years, there was no close correlation between the variation of the developmental score of the 18-year-old youth of minority nationalities and the change of climatic factors. (2) in 1985 and 2005, the development of the 18-year-old minority youth was larger in the northern region than in the southern region, and the developmental score was associated with the latitude of the earth and the annual sunshine hours. The annual air temperature difference was significantly positive correlation with other climatic factors, the development score and climatic factors were the first choice of regression analysis, boys were annual precipitation and annual sunshine hours, girls were annual sunshine hours and annual air temperature was poor. Conclusion: the natural environment factor is an important factor to influence the growth and development of minority youth, but the change of climatic factors in 20 years is not important to the growth and development of young people.
