摘要
采用灰色系统理论中的关联分析方法,对影响径流的各个因素进行分析,挑选出影响径流的主要因子,建立径流与主要影响因子之间的多元线性回归预测模型。通过实例证明,该方法简单可行,预测精度较高。
Through interaction analysis method in gray system theory, this paper analyzes all the factors which affect runoff, selects the main factors, and builds multivariate linear regression forecast model between runoff and factors. By means of experiment, this way is easy, effective and accurate.
