摘　　要：将粗糙集理论应用于模糊综合评判.该方法利用粗糙集理论中的知识约简方法挖掘评价指标,然后利用基于粗糙集理论中信息量的概念确定评价指标的权重,使模糊综合评判更简便易行、评判结果更加客观可信.A new method of assessment on environment quality based on rough set theory is present. This method makes use of knowledge reduction method of rough set to choose Estimate factor first. Secondly, rough information system is defined and a model of assessment is proposed based on estimate factors are weighted according to information quantity. Finally, an example is taken to show that this method is effective.
