摘 要: 为克服单因子评价法无法对海洋生态环境系统进行综合全面评价的问题,研究发展了多级灰关联评价方法对天津近岸海域的环境质量进行综合评价。结果表明:对天津近岸海域环境质量影响最大的环境因子是溶解态无机氮(dissolved inorganic nitrogen, DIN),溶解态无机磷(dissolved inorganic phosphorus, DIP)次之,而化学需氧量(chemical oxygen demand, COD)的影响最小;天津近岸海域4个海洋功能区中,汉沽农渔业区和天津东南部农渔业区的水质全部没有达到要求,需要重点控制。采用的多级灰关联评价方法为水环境质量评价开发了新途径,并可为海洋污染控制政策提供技术支持。
关 键 词: 环境工程学;海洋环境;水质评价;多级灰关联综合评价

Abstract: Single-factor evaluation method, which is widely used, cannot comprehensively evaluate the quality of marine ecological environment system. Thus, a new and advanced comprehensive evaluation method is needed. In this study, the multi-grade geay relational evaluation method was developed and applied in Tianjin coastal sea water quality evaluation. The results showed that the greatest impact environmental factors in Tianjin coastal area was dissolved inorganic nitrogen (DIN), followed by dissolved inorganic phosphorus (DIP), and chemical oxygen demand (COD) had least impact. In four marine functional zones of Tianjin coastal waters, two fishery (Hangu fishery and Tianjin southeast fishery) water quality did not meet the requirements and needed to focus on control. The multi-grade geay relational evaluation method developed in this study provides a new approach to comprehensively evaluate the quality of marine ecological environment system and technical support for marine pollution control policy.
Key words: environmental engineering; marine environment; water quality assessment; multi-grade grey relational comprehensive evaluation
