摘要
本文采用数据对比分析法,分析大兴安岭西坡根河的乌力库玛站和大兴安岭东坡呼玛河的塔河站的河流水质特征。同时选择呼玛河和根河水质资料分析大兴安岭北部林区典型流域饮用水水质状况。两条河流离子总量差别不大,在中国属较低水平。但是根河河水中金属离子的含量小于呼玛河,阴离子除HC03-外,根河均大于呼玛河。两条河流水的硬度和矿化度都较低,特别是根河河水溶解氧的含量充足、水质软。根河饮用水水质在世界天然水背景值内也属低值。
The river water qualities characteristics of the Wulikuma station and the Tahe station of the Huma, in the west of the Daxinganling were analyzed by data - compared analytical method and the drinking water quality of typical drainage area in the north of the Daxinganling was analyzed on the analysis of the Huma river and Genhe river data. the difference in contetent of total ions was small, which belongs to the low level in china. Contrasting the east river to the west, the mental gross of the Genhe river is lower than the Huma, but the ion gross of Cenhe is higher than the Huma except HCO3^-. The hardness and mineralization of the Daxinganling rivers is low. Especially the dissolved Oxygen （DO） content of the Genhe river is abundance, and water is soft.
