通过对不同月份内的一天大气花粉浓度的时空采样分析和同一月份不同日期的垂直高度的花粉浓度时空分布采样分析 ,结果表明 ,大气中的花粉主要分布在 5 0m以内的空间 ,但在 80m高空依然有一些花粉存在。大气花粉浓度的时空分布受风速、风向和温度等气象因素以及植物开花季节和种类的影响较大。除此之外 ,湿度和城市的高层建筑布局对大气花粉的时空分布也有一定程度的影响
Through the spatial and temporal sampling analysis of the atmospheric pollen concentration of one day in different months and the vertical and vertical pollen concentration of different months in the same month, the results showed that the pollen in the atmosphere mainly distributed in the space of 50m, but at 80m altitude There are still some pollen present. The spatial and temporal distribution of atmospheric pollen concentration is greatly influenced by meteorological factors such as wind speed, wind direction and temperature as well as the season and type of plant flowering. In addition, the spatial distribution of atmospheric pollen also has a certain degree of influence due to humidity and the city’s high-rise building layout
