【摘要】：基于对立统一与质量互变定理的可变模糊评价方法引入海水水质综合评价,构建基于对立统一与质量互变定理的海洋环境质量可变模糊评价模型,首先分析可变模糊评价方法的原理和方法,然后结合GIS栅格数据在表达空间信息方面具有的独特优势,以栅格数据为基础,利用地理信息系统空间叠置分析、地理信息系统空间建模等计算,建立基于多源栅格数据的海水环境可变模糊综合评价模型,得到莱州湾2004~2010年海水环境空间分布图。实践证明,该模型应用于海水水质综合评价是完全可行的,为海洋环境领域的多目标综合评价与决策提供了新的思路与方法。
[Abstract]:The variable fuzzy evaluation method based on the theorem of unity of opposites and mutual variation of quality is introduced into the comprehensive evaluation of sea water quality, and a variable fuzzy evaluation model of marine environmental quality based on the theorem of unity of opposites and mutual variation of quality is constructed. This paper first analyzes the principle and method of variable fuzzy evaluation method, then combines the unique advantage of GIS raster data in expressing spatial information, based on raster data, makes use of GIS spatial overlay analysis. Based on the spatial modeling of geographic information system (GIS), a multi-source grid data based variable fuzzy comprehensive evaluation model of seawater environment was established, and the spatial distribution map of sea water environment in Laizhou Bay from 2004 to 2010 was obtained. The application of the model to the comprehensive assessment of seawater quality has been proved to be feasible, which provides a new idea and method for multi-objective comprehensive evaluation and decision making in the field of marine environment.
