摘　　要：介绍了几种在环境质量评价中关键污染因子的确定方法 ,在此基础上提出了一种新的关键污染因子的确定方法———动态污染指数判别法。经过实例运用分析表明 ,该方法物理意义明确 ,简便易用。通过对某个时间段内污染物原始监测数据的灰色处理 ,从动态演变中找出关键因子 ,客观地判别各污染因子所起的作用 ,对各因子在下一个时间段的发展趋势作出预测判断 。Methods to determine key pollution factors in environmental quality evaluation were discussed. A new method, Active Pollution Indicators Discrimination Method, is put forward. With the grey treatment of rudimentary data during certain period, the key factors were indicated. Each pollution factors was judged and evaluated, and the development trend was reached. This method is simple and accurate.
