摘要
根据重庆十年能见度及气象数据和大气监测数据,作出了不同风向上能见度玫瑰图和多元回归模型.结果显示,水平能见度距离的降低,主要是空气污染引起的.
ABSTRAT Data of visibility, meterological parameters and atmospheric moniter- ing for ten years were analyzed using mutivariato statistical methods in Chongqing urban city. It leads to a wind rose of visibilityin different wind directions and a regression model of multivariate for visibility. The result suggests the decrease of horizontal visible distane is dominated by the increase of airborne pollutions, especially by SO_2.
