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,本研究发展
了多级灰关联评价方法来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性无机氮,溶解态无机磷次之,而化学需氧量的影
响最小;天津近岸海域四个海洋功能区中,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。本研究中的多级灰关联评价方法为水环境质量评价开发了新
的途径,并可以为海洋污染控制政策提供技术支持。

Abstract: Single-factor evaluation method, which is widely used, prehensively
evaluate the quality of marine ecological environment system. Thus, a new and advanced
comprehensive evaluation method is needed. In this study, the multi-level gray 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
anic nitrogen, followed by dissolved anic phosphorus, and chemical oxygen demand
had least impact; In four marine functional zones of Tianjin coastal waters, two fishery water
quality did not meet the requirements and needed to focus on control. The multi-level gray
relational evaluation metho
