Investigation into the influence of microclimate effect on the spatiotemporal distribution characteristics of air negative ions in urban forest parks

with the development and progress of the times, the pace of urbanization in our country is getting faster and faster, and the scale of building cities is also getting bigger and bigger. Since then, the pressure on the ecosystem has also been increasing, gradually aggravating the deterioration of the ecological environment, and it is urgent to improve the living environment of urban residents. Among them, the impact of air quality on the environment is the most important, and to better evaluate whether the air is good, it is necessary to use the important indicator of air negative ions. In this paper, Jingyuetan National Deep Forest Park in the southeast of Changchun City was selected as the research area, the air negative ion concentration was detected in the botanical garden in the park, and the relevant data collected were compared and analyzed by mathematical statistics, and the influence of microclimate effects on the temporal and spatial distribution characteristics of air negative ions in urban deep forest parks and the relationship between the two were studied.
