通过对１９８６年我国主要低空各层平面流场、经纬圈垂直剖面图以及国内各测站的年、月平均风场资料的特征分析，得到各站的边界层内普遍存在一个最大风速区的结论，并归纳出低空风随高度分布的６种典型廓线。初步得出：我国污染物输送在水平方向及垂直方向上均以国内输送为主，但在东部、南部沿海与周边国家和地区亦存在互有输入、输出的输送 Based on the analysis of the vertical and horizontal latitudinal and / or latitudinal flow fields and the annual and monthly mean wind field data of all stations in China in 1986, we get the conclusion that there exists a maximum wind speed region in the boundary layer of each station. , And summed up the six typical profiles of the low-level wind distribution with height. It is concluded that the transport of pollutants in China mainly takes the domestic transportation in the horizontal direction and the vertical direction, but there is also the input and output transportation in the eastern and southern coastal areas and neighboring countries and regions
