黄河源区水域离子特征分析

Character analysis of ions in the source region of the Yellow River

运用数理统计方法对源区水样、土样的离子质量浓度进行分析,确定源区离子变化特征。离子的典型变化通过趋势图加以表现,具体说明当地气候条件、岩石、土壤以及水文特征对于源区干流离子质量浓度的影响,为源区水资源的保护提供依据。分析结果表明:源区作为黄河产水区,由于受到人类影响相对较小,水质较好。干流中离子质量浓度的变化主要是受当地气候、支流、土样以及水体水文特征的影响。

The Yellow River is faced with problems of water quality deterioration and quantity reduction. As the main water supplier of the Yellow River, the source region is of great worth to be studied on water quality and its influencing factors. Statistic method is introduced in this paper to analyze the concentration, variation, and distribution of ions in water and soil samples in the source area. Impacts of weather, rock type, soil and hydrologic characteristics on ion concentration are illuminated, providing a base for water resources protection in source area. The source area of the Yellow River is found to be of good water quality because of little human impacts. Variation of ion concentration in mainstream is mainly influenced by weather, branch, soil, and hydrologic characteristics.
