摘要
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。
By analyzing the feature of the data from mainly different low-level streamline fields in China, figures of zonal and meridional cross-section and the yearly, monthly mean wind fields over different weather stations in China, the conclusion is drawn that there is a maximal wind speed area in the boundary layer over all the stations, and 6 typical profiles of low level wind speed with altitude are got. The preliminary conclusion is that the pollutants mainly transport the horizontal and vertical directions in China, but the inflow and outflow of pollutants also exist between the east and south parts of China and its adjacent countries and areas.
