松花江哈尔滨段城市水环境质量评价

为了科学地对松花江哈尔滨段水环境质量进行评价,基于水环境功能区划,采用灰色关联度法将其分为4个区域,运用主、客观相结合的方法分区域建立相应的评价指标体系,使用模糊综合评价法进行水质评价,同时,验证指标体系构建的合理性.结果表明:构建的指标体系能够反映研究对象水环境质量;除阿什河口内水质评价结果为V类,达不到水环境功能区划要求外,其他区域水质均能达标.研究结果将有利于促进水资源的科学管理和有效利用,研究方法可为水环境质量评价提供新的思路.

Study on water environmental quality in Harbin section of the Songhua River

In order to scientifically evaluate the water environment quality in the Harbin section of Songhua River, the section was divided into four regions by using gray correlation method based on the water environment functional zoning. The corresponding evaluation index system was set up by using the method of combining subjective and objective points. The water quality was evaluated by using fuzzy comprehensive evaluation method, and the rationality of index system was verified simultaneously. The results showed that the constructed index system could reflect the water environment quality in the Harbin section of Songhua River. Water qualities in all regions could meet the requirements of water environment functional zones except for the Ashi Estuary whese evaluation results was V class. The results of the study would be beneficial to promote the scientific management and effective utilization of water resources, and the method could provide a new idea for water environmental quality assessment.
