摘　　要：将灰色系统原理引入环境质量评价中,可通过对某个时间段内污染物原始监测数据的灰色处理,从动态演变中找出最大贡献因子,客观地判定各污染因子所起的作用。并对各因子在下一个时间段的发展趋势作出判断,增加了评价的准确性。经过实例运用分析表明,该方法科学、简便、精确、所得结果与唐山市大气环境质量现状相符合,具有较强的实际应用价值。By introducing grey system principle into environment quality appraisal, the key factors were found out in the dy- namic evolution via treating primitive monitoring data of pollutants in certain time sections with grey system, in a bid to determine the functions of each polluting factors. The development trends of various factors in the following time sections were also studied to increase the appraisal accuracy. Analysis on examples showed that this method is scientific, simple and precise. The result ob- tained complied with present situations of Tangshan atmospheric environment, providing strong practical application value to re- searches of this field.
