摘　　要：通过设置不同的太阳辐射强度形成了不同特征的海陆风环流,模拟分析了不同时段释放的大气污染物与太阳辐射强度之间的关系。结果表明:太阳辐射强度对海陆风的风速具有重要影响;海陆风期间释放污染物的扩散范围和深入海陆两侧的距离都与太阳辐射强度有明显关联;太阳辐射较弱时海陆风对污染物的扩散效果较差,近海岸线地区污染物日平均浓度较高。The relationship between atmospheric pollutants released at different times of the day and the intensity of solar radiation was simulated and analysed by setting different solar radiation intensities to form a sea-land breeze circulation of different characteristics.The results show that:the intensity of solar radiation has an important influence on the wind speed of the sea-land breeze;the dispersion range of pollutants released during the sea-land breeze and the distance of penetration to both sides of the sea and land are significantly related to the intensity of solar radiation;the dispersion effect of the sea-land breeze on pollutants is poor when the solar radiation is weak,and the daily average concentration of pollutants is higher in areas near the coastline.
