摘　　要：通过对西藏尼洋河水样中的溶氧值、水温、无机营养含量,pH和悬浮物等分析发现,尼洋河的溶氧值在5-9月低,11-3月高,水温5-9月高,1、3和11月低,pH为7.9-8.4之间,呈碱性,悬浮物为0-16.4 mg.L^-1,溶氧值,pH,悬浮物和水温随时空变化而改变;硝酸盐氮〉氨氮〉总磷〉亚硝酸氮,金属成分的含量以Zn最高.The analysis of oxygen production, water temperature, content of inorganic nutrition, pH, suspended substance, and the content of metal of Niyang river shows that the oxygen production. In this river is low in May to September and high in November to March, water temperature is high in May to September and low in January ,March and November. pH is between 7.9 and 8.4 ; Suspended substance of Niyang river is between 0 mg/L and 16.4 mg/L. content of nitrate nitrogen is more than ammonia nitrogen which is more than phosphor . The most metal in this river is Zn. The oxygen production, water temperature, content of inorganic nutrition, pH, suspended substance, and the content of metal of Niyang river change with the change of space time.
