This paper reports the investigation and analysis of the status and dynamic changes of ecological environment quality in the main stream of Songhua river basin. The evaluation index system was established and the eco-environment quality in the year of 2000 and 2008 was studied in depth. Based on our research, the trend of dynamic changes of the eco-environment quality and its origins have been further discussed: In the year of 2000, the range of evaluation index covered from 0.31 to 0.47. Harbin and Yichun was relatively better than the rest of study areas. In the year of 2008, except districts of Daqing and Qitaihe, the environmental quality of Songhua river basin has entirely improved, wherein the evaluation index of the eco-environment covered from 0.31 to 0.57. Particularly, the eco-environment quality of Hegang and Shuangyashan has obtained significant improvement, whereas the improvement of Jiamusi was not obvious. According to the evaluation results, the environmental quality in the study area has an upward trend with the average growth rate 0.13% per year.
本论文报告了对松花江流域干流生态环境质量的现状和动态变化的调查与分析。建立了评价指标体系，并深入研究了 2000 年和 2008 年的生态环境质量。基于我们的研究，进一步探讨了生态环境质量动态变化的趋势及其成因：2000 年，评价指标范围为 0.31 至 0.47。哈尔滨和伊春的情况要好于其他研究区域。2008 年，除大庆和七台河地区外，松花江流域的环境质量已全面改善，生态环境评价指数为 0.31 至 0.57。特别是鹤岗和双鸭山的生态环境质量得到了显著改善，而佳木斯的改善则不明显。根据评价结果，研究区域的环境质量呈上升趋势，平均每年增长 0.13%。
