摘要
水质评价是通过一定的数理方法对水环境系统进行环境要素分析,对其做出等级评价,为区域环境系统的治理规划提供依据。依据云南九大高原湖泊水质监测数据,选取pH、DO、COD、TN、TP、氨氮、COD等7个常规水质监测指标作为评价指标,基于模糊综合评价法、灰色关联分析法、主成分分析法和集对分析法4种水质综合评价法,对云南九大高原湖泊进行水质评价,并进行比较分析。比较结果显示,4种方法得到的水质评价结果有所不同,且评价方法各有特点,其中的模糊综合评价法和集对分析法的评价结果更为接近水质等级公示结果,相对更适合应用于高原湖泊水质评价。
Water quality assessment is to analyze the environmental factors of water environment system by mathematical method and to make a grade assessment,which provides a basis for the governance planning of regional environmental system.Based on the water quality monitoring data of nine plateau lakes in Yunnan Province,seven conventional water quality monitoring indexes,including pH,DO,COD,TN,TP,ammonia nitrogen and CODare selected as evaluation indexes.The water quality of nine plateau lakes in Yunnan Province is evaluated based on fuzzy comprehensive evaluation method,grey relational analysis,principal component analysis and set pair analysis respectively,and the assessment results are compared.The comparison results show that the evaluation results obtained by the four methods are different,and each evaluation method has its own characteristics.Among them,the evaluation results of fuzzy comprehensive evaluation method and set pair analysis method are closer to the published results of water quality grades,which are relatively suitable for the water quality evaluation of plateau lakes.
