摘　　要：针对松花江干流哈尔滨段近年来水质健康状况,寻求可持续的、合理的开发和保护方式。从松花江水质状况出发,构建河流水质健康评价指标体系,建立熵权物元可拓模型,结合各指标的时间序列的变化信息对河流水质健康状况进行动态评价。综合评价结果表明,松花江干流哈尔滨段2015-2019年河流水质健康等级整体处于“健康”和“亚健康”等级,评价结果科学合理。To study the health status of Harbin section of Songhua River trunk stream in recent years,and to seek sustainable and reasonable development and protection methods.In this study,the river water quality health evaluation index system was constructed based on the river water quality.The entropy weight element extension model was established,and the river water quality health status was dynamically evaluated by combining the change information of the time series of each index.The comprehensive evaluation results show that the health grade of water quality in Harbin section of Songhua River trunk stream from 2015 to 2019 is“healthy”and“sub-healthy”,the evaluation results are scientific and reasonable.
