摘要
利用灰色变权聚类分析方法研究了城市空气质量问题.以国家城市空气质量分类标准为依据,以城市空气的主要污染物为聚类指标,对7个采样点空气质量监测数据建立了灰色聚类模型,为综合分析城市空气质量提供科学而准确的依据.
Grey variable weight clustering is adopted to analyze urban air quality. Based on China＇s air quality classification standards, with the main pollutants in urban air as the cluste ring index, the grey clustering model of the air quality monitoring data of seven cities is estab lished. The study is to provide scientific and accurate reference for synthetic analysis of urban air quality.
