灰色系统关联分析方法在融雪径流模式预报因子筛选中的应用

APPLICATION OF ANALYSIS METHOD OF GREY COGNATE DEGREE ON SELECTING FORECASTERS IN SNOWMELT RUNOFF MODEL

本文用灰色系统理论的关联分析方法研究影响黄河上游春季融雪径流的各种因素与径流的关联程度,从而为融雪径流模式(简记为SRM)预报因子的合理确定提供依据。这种分析方法与传统的数理统计方法相比,省时省力且准确程度较高,为多变量相关分析提供了一个令人鼓舞的途径。

In this paper, the analysis method of cognate degree in Grey Theory was used for researching the cognate extent between various affacting factors and snowmelt runoff in the upper reaches of the Yellow River in order to provide reasonable foundation for determinig forecasters in snowmelt runoff model (SRM). As compared with some classical mathematic statistics methods, this analysis method has many advantages, such as simple computation, high accuracy, etc., which offers new way for multivariate analysis of interrelation.
