摘　　要：在一般的多元回归分析中,通过分析因变量和自变量之间的关系,可以预测因变量的值。但是,如果考虑各自变量不同时段对因变量的影响,这时常常采用积分回归分析法。本文介绍了积分回归的基本原理,以及使用Visual Basic(简称VB)编程工具设计积分回归程序的过程。在农业、经济、工业等领域利用积分回归统计程序可以简化积分回归分析过程,所得到的积分回归方程能够真实反映出各自变量不同时段对因变量的影响。该积分回归统计程序界面简单、便于操作。In normal multivariate regression analysis,the relations between independent variable and dependent variable is analyzed,and the value of dependent variable can be forecasted.However,if the effect independent variable to dependent variable is considered in disparate period time,the analysis method of integral regression need to be adopted.This paper gives the basic principle of integral regression, and the procedure of integral regression is designed by using Visual Basic （VB）programming tools. In domain of agriculture, economic,industry etc, the procedure of integral regression adopted can be simplify the process of integral regression analysis,and integral regression equation can reflect the effect independent variable to dependent variable in different time.The procedure has good interface but, and it＇s also easy to operate.
