对灰色聚类法进行改进，引入正态分布白化权函数。白化权函数改进为曲边梯形结构可有效解决边缘零权重问题。应用改进后的灰色聚类模型对粤港珠江三角洲区域2006-2013年大气环境质量进行评价，聚类结果表明研究区域大气质量总体上逐渐提高，均为Ⅱ类。改进后的灰色聚类法评价结果客观、准确。

To improve grey clustering method, normal distribution of whiteness function was introduced. The whiteness function can solve the zero weight problems well because it build relationship between sample value and gray classifications using albino function of index type. Based on improved grey clustering method, the atmospheric environment in Hong Kong and Pearl River Delta from 2006 to 2013 was evaluated. The result shows that the air quality improved gradually overall and met the secondary standard, and improved-grey-clustering method made the evaluation results more objective and fair.
