摘　　要：以三江源高寒湖泊扎陵湖为研究对象,在扎陵湖湖泊设置3个采样点,分别对扎陵湖水体中总有机碳(TOC)、总氮(TN)、总磷(TP)、氨氮(NH4+-N)、硝酸盐氮(NO3--N)、亚硝酸盐氮(NO2--N)分布特征进行了研究,对总氮、总磷的相关性进行分析,对照《地表水环境质量标准》(GB3838-2002),并采用超标率和超标倍数的评价方法对水质进行了评价。结果表明,扎陵湖水体中总氮含量为0.58 mg/L,总磷含量为0.018 mg/L,氨氮含量为0.115 mg/L,硝酸盐氮含量为0.150 mg/L,亚硝酸盐氮含量为0.001 3 mg/L,TOC含量为0.382 mg/L。总氮和总磷的相关系数R2=0.313 9,说明总氮总磷的相关性较差,总氮、总磷含量高于《地表水环境质量标准》规定的Ⅰ类水质标准,氨氮含量低于《地表水环境质量标准》规定的Ⅰ类水质标准。Taking alpine Zhaling lake of San Jiang Yuan as the study object, three sampling points were setup to study distribution characteristics of total organic carbon（TOC）, total nitrogen（TN）, total phosphorus（TP）, ammonia（NH4^＋-N）, nitrate nitrogen（NO3^--N）, nitrite（NO2^--N） in Zhaling lake respectively, then the correlation between total nitrogen and total phosphorus correlation was analyzed. Using to the ＂surface water Quality Standard＂（GB3838-2002） as reference, the water quality was evaluated by methods of excessive rates and excessive multiple. The results showed that, the content of total nitrogen in Zhaling lake was 0.58 mg / L,the content of total phosphorus was 0.018 mg / L, the content ammonia nitrogen was 0.115 mg / L, the content of nitrate nitrogen was 0.150 mg / L, the content of nitrite nitrogen was 0.001 3 mg / L,the content of TOC was 0.382 mg / L. Correlation coefficient of TN and TP was R^2=0.313 9, illustrting the correlation of TN and TP was poor, the contents of total nitrogen and total phosphorus were higher thanⅠwater quality standard of ＂Surface Water Quality Standards＂, ammonia content was lower thanⅠwater quality standard of ＂surface Water Quality standards＂.
