摘　　要：本文以松花江黑龙江段5个断面水质为目标,采用综合水质标识指数法对其在2003-2010年间的水质进行了综合评价。结果表明,高锰酸盐指数和总磷在松花江黑龙江段超标频次较高,超标程度较深,是影响松花江水质的主要污染物。同时应用Speraman秩相关系数法对松花江黑龙江段5个断面在近8年间的水质变化趋势进行探究,分析结果表明松花江黑龙江段5个断面中江南屯断面水质呈显著好转趋势,其它4个断面水质比较稳定。This study uses comprehensive water quality identification index method to evaluate the water quality of Heilongjiang section of Songhuajiang River based on the observation data of five river segments during 2003-2010. The results showed that the potassium permanganate index and total phosphorus were the main pollutants in Songhuajiang River＇s Heilongjiang section due to their high frequency and degree over the standard. At the same time, the Speraman rank correlation coefficient method was applied to analyze the water quality variation trend of the five segments during the past 8 years. The result showed that the water quality of Jiangnantun segment was improved intensively. However, the water quality of the four other segments was stable during the past 8 years.
