摘要
在大气环境影响评价工作中，对于多源问题通常采用逐个计算叠加的方法。本文介绍了在大型水泥厂大气环境影响预测中，对数量众多的粉尘排放源进行简化处理的一种方法。在瑞昌水泥厂的环境影响评价中，我们采用了这种方法，并对这种方法得到的结果进行了比较验证，讨论了这种方法的合理性和可行性。通过这种简化处理，可以使大气预测工作更简单化，更省时。
In Air Environment Impact Assessment,the contributions of all sources to the concentration at a given receptor are usually calculated separately and then added to give the total concentration,that means more works and longer time. The writer of this thesis provides a method of simplifying these many sources producing suspended particle in the Air Environment Impact Prediction of grand cement plant. We had used this method in the Environment Impact Asscssment of Richang cement plant and we had compared it with the old and analysed it.
