摘要
本文以平遥县城及周边区域环境空气质量监测结果为依据,采用具有全局优化的遗传算法(GA)对平遥县及周边区域大气环境质量污染现状进行评价。用大气污染危害指数的普适公式和参数优化后的污染危害指数公式确定污染危害指数的取值范围与评价级别之间的对应关系,由此得出较符合平遥县及周边区域实际的评价结果,同时针对具体情况对此结果进行简单的分析。
Based on the monitored data of the air quality of Pingyao county town and the area nearby,the situation of atmospheric pollution was assessed using a global optimized genetic algorithm(GA).By applying the universal formula of atmospheric pollution hazard index and the pollution hazard index formula with optimal parameter,the correspondence between the numeric area of pollution hazard index and the assessment levels was determined,from which assessment results coinciding with the local situation were obtained and the results were analyzed according to the specific situation.
