　　重庆市主城区空气污染程度具有较强的季节特征：整个冬季污染较重，夏半年则相对较轻；三峡工程成库后，库区温度、湿度、降水、雾情、风力、风速等局地气象因素因水位抬升而发生改变，重湿和暖冬的气候特征尤为加重；冬季，由于水温高于气温，下垫面空气受到水库的加热，使得冬季的逆温状况相对减弱，污染物在垂直方向上得以扩散；而在夏季由于太阳辐射，水汽蒸发，空气湿重致使稳定度增加，对污染物的扩散造成不利，预测在排放不变的情况下，预计在排放不变的情况下，重庆市主城区空气污染程度全年平均大约有0．80％的好转，冬季蓄水期的5个月有1．42％的好转，夏季有两个月会有0．22％-0．37％的恶化；成库后2年空气污染指数数据验证表明，空气质量好转，污染程度月度偏差缩小。

Air pollution in Chongqing City has a strong seasonal characteristics ,heavily polluted through the winter , relatively lighter in the summer ,After the three gorges project finished ,local meteorological factors such as tempera-ture ,humidity ,wind speed ,precipitation ,fog changed by the water level lifts .Heavy wet and mild winter is partic-ularly aggravated .In winter ,due to the water temperature higher than air temperature ,the temperature inversion in relatively less ,pollutants easy to spread in vertical direction .In summer ,Due to solar radiation ,water vapor evapo-ration ,air stability increase negatively on pollutant diffusion .Is expected to be discharged the same cases ,air pollu-tion in Chongqing City annual average improvement in some 0 .8% ,1 .42% improved during the 5 months of winter storage period ,two months in the summer will have 0 .22% to 0 .37% deterioration ..The air pollution index data indicated that after the reservoir store water ,air quality improved and monthly deviation reduced ..
