为了科学地评价东江湖水质，选取了东江湖10个常规断面，根据11个水质指标进行评价。利用主因子分析模型分析了污染成因，并与单因子指数法、平均综合评价法得到的结果进行了比较。研究结果表明：10个断面水质均达到国家地表水Ⅲ类标准，其中小东江、头山、白廊3处水质状况最好；在两个季度中， F1和F3均在黄草镇燕子排断面出现最高点， F2最高点出现在高龙村滁口。东江湖总体水质良好，但码头、黄草镇燕子排和高龙村滁口断面比其他断面水质差，需采取有效防控措施。

For the purpose of the scientific evaluation water quality assessment of Dongjiang lake, 10 conventional sections and 11 water indexes are chosen from Dongjiang lake to constitute evaluation by the model of main factor analysis. The main factors affecting water quality are found out by using the main factors, and compared with the single factor index method and the average comprehensive evaluation method to find the advantage of the main factor analysis. The research shows that 10 conventional sections all reach quality III. In which, Small Dongjiang, Toushan and Bailang are better. In the first main fator score F 1 and F 3 , the highest score is Yanzipai in Huangcao town, and the second main factor score F 2 is Chukou in Gaolong village. Above all, the water quality of Dongjiang lake is well, but compared with other sections, the water quality of Matou, Yanzipai and Chukou are relatively poor, and which should be taken effective measures to prevent and control.
