摘　　要：选取2002年1月和7月分别代表冬、夏季,利用MM5v3.7模拟了辽宁中部城市群的边界层特征,着重分析了各层的月平均风场分布。结果表明:无论冬季还是夏季,大气污染物均以输入的方式进入辽宁,冬季容易造成辽宁中部城市群的局地污染,夏季则不会造成严重的污染。MM5v3.7 was used to simulate the boundary layer characteristics of the city group in middle Liaoning, based on the data of January and July in 2002 representing winter and summer, respectively. And the distributions of average wind fields on each layer were mainly analyzed. The results showed that the main atmospheric pollutant was imported to Liaoning whether winter or summer, and this will bring in local pollution of the city group in winter, but it will make nothing serious pollution in summer.
