通过对博斯腾湖的扬水站、金沙滩、大河口、中央区、白沙梁子5个采样点在2010－2013年水质参数中pH 值、溶解氧(DO)、总磷(TP)、氨氮(NH 3-N)、硝酸氮(NO 3-N)、亚硝酸氮、BOD5、COD、硫酸盐和氯化物的变化及污染物入湖量的调查与分析。结果表明,扬水站附近区的水质较好,其限值介于地表水水环境质量标准Ⅰ到Ⅲ级之间。其他4个点的水质比较差,除了大河口点氯化物浓度＜250 mg/L 之外,其他3个采样点硫酸盐及氯化物均超过限值(250 mg/L),4个点 COD 值均超标,属于Ⅳ类；其他污染物浓度也快速升高,故此水域水体属于Ⅳ类标准。针对博斯腾湖水环境现状,提出了改善水质的对策。

The samples from Yangshui station,Jinshatan,Dahekou station,Zhongyangqu station, Baishaliangzi station of Bosten Lake were collected in 2010-2013 to analyze and investigate pH,DO,TP, ammonia nitrogen(NH 3-N),nitrate-nitrogen (NO 3-N),nitrite-nitrogen,BOD5 ,COD,sulphate and chloride and inflow of pollutant in Bosten Lake.Result showed that there was better water quality of Yanshui sta-tion,whose limitation value was between grade Ⅰand Ⅲ of the surface water environment quality stand-ard.However,water quality in other stations was poor,except chloride concentration<250 mg/L of Dahek-ou station,shlphate and chloride of other three stations all were more than limitation value (250 mg/L), COD of the four stations all surpassed the set standard,which belonged to brade Ⅳ;The concentration of other pollutants fast increased also.So water space and water body belonged to grade Ⅳ.Finally,some strategies were put forward for serious current situation of the Bosten Lake.
