摘　　要：增量趋势法是一种判别区域环境质量主控因子的常用方法。通过对增量趋势法的模型进行修订,并以天津海域的环境状况为例,对其2007年的环境质量主控因子进行了排序,提出目前天津海域的环境质量主控因子主要是无机氮和石油类物质,污染治理也应针对这两类物质进行,最后对新模型在实际应用中的意义进行了说明,为保证天津海域环境的可持续发展提供了实际依据。Incremental tendency method is used to discriminate master factors of regional environmental quality.In this paper,incremental tendency method has been revised.Taken Tianjin sea area as an example,the collation of environmental quality master factors in 2006 has been listed.It shows that environmental quality master factors of Tianjin sea area are mainly inorganic nitrogen and petroleum substances,and pollution management should also aim at these types of substances.Finally the significance of new model in application has been explained.It provided practical basis for sustainable development of Tianjin sea area.
