摘要
分析2012年赛里木湖和喀纳斯湖湖区和主要出入湖河流水质,测定总有机碳（TOC）和高锰酸盐指数（CODMn）,研究他们之间的相关性,建立TOC和CODMn的线性回归方程,统计计算值与实测值的相对误差.研究结果表明,CODMn和TOC呈现良好相关性,相关系数为0.854（（p＜0.01,n=42）;赛里木湖和喀纳斯湖通过TOC计算CODMn的回归方程分别为CODMn=1.302TOC＋0.36（R =0.966,α＜0.01）和CODMn=0.594TOC＋0.661（R=0.823,α＜0.01）;计算值与实测值相对误差范围是3.2％～16.7％.
Water samples of lakes and rivers were collected in Sailimu Lake and Kanas Lake in 2012. Total organic carbon （TOC）and potassium permanganate index （CODMn）were analyzed. Correlation analysis was carried out between them. Linear regression equation was built between CODMn and TOC, and errors between calculated and measured values were analyzed. Results showed significant correlation between CODMn and TOC, and the correlation coefficient was 0.854 （（P 〈0.01, n =42）. Linear regression equations between CODMn and TOC of Sailimu Lake and Kanas Lake were CODMn = 1. 302TOC ＋ 0.36 （ R = 0.966,α 〈 0.01 ） and CODM, = 0.594TOC ＋ 0.661 （ R = 0. 823, α 〈 0.01 ）, respectively. TOC was used to calculate CODMn, and the relative errors range from 3.2% to 16.7%.
