1999年 8月对格尔木河—达布逊湖流域进行了系统考察 ,并对其地表水体取样分析后发现 ,河水水化学分布空间上从源头至湖中逐渐咸化 ,表现出明显的地貌分区性特征 ,且东河段水质异常咸化 ;时间上河水矿化度总体表现为逐年上升的趋势 ,湖水则相对稳定 .作为流域农牧业发展的水源地和近几年格尔木市移民建设的重点地区 ,其地表水体水化学的时空异常变化应引起足够的重视 .
In August 1999, a systematic investigation of the Golmud-Dabson Lake basin was carried out. Sampling and analysis of its surface water body showed that the chemical distribution of river water was gradually salted from the source to the lake in space, showing obvious zoning And the water quality of Donghe section is abnormally salinized.The temporal salinity of river water shows a trend of rising year by year while the lake water is relatively stable.As a water source area for the development of agriculture and animal husbandry in the basin and the key area for emigrant construction in Golmud in recent years , The spatio-temporal anomaly change of water chemistry in surface water should be given enough attention.
