摘要
TOPSIS法作为一种多目标决策方法,可应用于土壤环境质量综合评价中。介绍了TOPSIS法的原理和算法步骤,并以福州市表层土壤为例,探讨了TOPSIS法在土壤环境质量评价中的应用。研究结果表明,TOPSIS法结合土壤环境质量标准不仅能确定各评价对象环境质量等级,同时也能进行多个对象评价和不同评价对象间质量的优劣比较。TOPSIS法在土壤环境质量综合评价中具有较高的合理性和适用性。
TOPSIS is a method for multi-objective policy-decision, which can be applied in the environment quality evaluation of soil. In this paper, principles and calculation procedures of TOPSIS method were intro- duced in detail. And the TOPSIS method was applied in the evaluation of topsoil environment quality in Fuzhou City. The results showed that TOPSIS method, combined with the environmental quality standard for soils, not only could confirm the quality degree of every evaluation object, but also could assess more objects at the same time and make comparison between different evaluation objects for environment quality. TOPSIS method is reasonable and applicable in the soil quality assessment.
