摘要:

贴近度分析法是一种具有模糊识别功能的评价方法,对等级划分具有一定适用性,广泛应用于土壤重金属污染水平和水环境质量的评价。本文通过对辽河干流铁岭段河岸带进行监测,将贴近度分析法应用于该河岸带的健康评价中,使用模糊评判法进行对比研究,得到现阶段辽河干流铁岭段河岸带的健康等级为良好状态,并根据评价结果与实际状况的吻合度和评价结果自身的偏差度进行方法适宜性检验,最终确定贴近度分析法在河岸带的健康评价中具有一定适宜性。

Abstract: The approaching degree is a fuzzy evaluation method which has a recognizing function. This method is used for grading division and has certain applicability. Now it has been widely used in evaluation on pollution status of heavy metals in soil and water environmental quality. In this paper, based on monitoring the riparian zone in Tieling section of Liao River, the approaching degree method was applied to assess the riparian health. The riparian zone of Tieling section of Liao River was at a good healthy level. The suitability of the method was examined according to both the goodnessoffit between the evaluation result and the actual situation, and the deviation degree of the evaluation results. We concluded that the approaching degree method was suitable for the riparian health assessment.
