摘要
环境是一个“灰色系统”，可以将灰色聚类分析应用到大气环境评价中。灰色聚类可按６个步骤进行：①给出聚类白化值；②确定灰类的白化函数；③求标定聚类权；④求聚类系数；⑤构造聚类行向量；⑥聚类。将灰色聚类分析方法应用于某油田８个主要矿区的ＳＯ２、ＴＳＰ和ＮＯｘ污染物，得出它们的大气环境质量的相应等级。
Environment is a “grey system”,so grey cluster analysis can be ap-plied to atmospheric environment assessment. Grey clusters can be done in six steps:1.Give cluster whitening value;2. Determine the whitening function of grey group; 3. Find calibration cluster weight;4.Find cluster coefficient;5. Form cluster row vector;6. Clus-tering.Apply grey cluster analytical method to SO2, TSP and NOxpollutants at eight main fields in a certain oil field and obtain the corresponding grades of their atmospheric environment quality.
