Along with the rapid development of economy and the increase in the high buildings in the city,the activity space of people has risen to 40m~100m from the ground,so there is a wide concern among people about the situation of the particle pollution of the atmosphere vertical space.The paper studies the vertical distribution of the quality density and particle size distribution of the inhalable particles,obtains the distribution law in the vertical space of the inhalable particles,establishes the regression equation of the PM10 distribution with the height,studies the granularity distribution of the floating dust samples in different height and further validates the vertical distribution law of PM10 increasing with the height as the content of the fine particles increase at the same time.
