摘　　要：相关分析和偏相关分析是研究两个或两个以上变量之间密切程度的两种常用的统计方法。论述了相关系数和偏相关系数的计算方法。通过计算某城市燃气日负荷与其影响因素的相关系数和偏相关系数,分析了各影响因素对燃气日负荷的影响程度,指出了在进行能源消费影响因素的相关分析和偏相关分析时应注意的问题。The correlation and partial correlation analyses are two conventional statistical methods for studying the close degree between two or more variables. The calculation methods of correlation coefficient and partial correlation coefficient are described. The influence degree of the different influence factors on the daily gas load is analyzing by calculatingthe correlation coefficient and partial correlation coefficient between the daily gas load of a city and the influence factors. The problems to which attention should be paid in the correlation and partial correlation analyses of influence factors of energy consumption are pointed out.
