汾河干流水质变化驱动力计算研究 The Driving Force of Water Quality Change at Fenhe River

Abstract

近年来，汾河干流的水污染日益严重。为了更好地对汾河流域进行管理和规划，选取6个气象和非气象因素，作为汾河干流水质变化的因素影响因子。运用依据灰色关联度分析理论，进行驱动力分析计算，结果表明：影响汾河干流水质的驱动力综合排列顺序为：工业(0.739) > 生活(0.710) > 温度(0.703) > 径流(0.688) > 相对湿度(0.681) > 降雨量(0.641)。 The water pollution problem is getting more serious at Fenhe River in recent years. For the better management and planning river, six meteorological and non-meteorological factors were selected in this paper. The driving force of Fenhe River water quality change was calculated based on gray correlation analysis theory. The results show that the sequence of affecting the Fenhe river water quality driving force is: industrial (0.739) > life (0.710) > temperature (0.703) > runoff (0.688) > relative humidity (0.681) > rainfall (0.641).
