【摘要】:基于對立統(tǒng)一與質(zhì)量互變定理的可變模糊評價方法引入海水水質(zhì)綜合評價,構(gòu)建基于對立統(tǒng)一與質(zhì)量互變定理的海洋環(huán)境質(zhì)量可變模糊評價模型,首先分析可變模糊評價方法的原理和方法,然后結(jié)合GIS柵格數(shù)據(jù)在表達空間信息方面具有的獨特優(yōu)勢,以柵格數(shù)據(jù)為基礎(chǔ),利用地理信息系統(tǒng)空間疊置分析、地理信息系統(tǒng)空間建模等計算,建立基于多源柵格數(shù)據(jù)的海水環(huán)境可變模糊綜合評價模型,得到萊州灣2004~2010年海水環(huán)境空間分布圖。實踐證明,該模型應(yīng)用于海水水質(zhì)綜合評價是完全可行的,為海洋環(huán)境領(lǐng)域的多目標(biāo)綜合評價與決策提供了新的思路與方法。
[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.
