Abstract

The invention discloses a method for establishing an atmospheric pollution space-time transformation evaluation prediction model, which comprises the following steps of: S1, simulating a meteorological field at a selected moment for a research area, and predicting and measuring the meteorological field to obtain meteorological information at the moment after the moment is selected; s2, dividing grids according to the environmental factors of the research area, and detecting the atmospheric pollution degree on the grids. A user studies the environmental factors of the area, and divides grids inthe research area; the atmospheric pollution degree is detected on the grids; an isoconcentration curve of pollution is drawn according to the detected grid data and a contour line method of the topographic map of the research area; and finally, a pollution model is established according to the isoconcentration curve and the concentration change gradient, and the atmospheric pollution degree in the research area is evaluated according to the pollution model, so that prediction of atmospheric pollution in a space-time transformation state is facilitated.

Description

technical field [0001] The invention relates to the technical field of air pollution measurement and evaluation, in particular to a method for establishing an air pollution time-space transformation evaluation prediction model. Background technique [0002] Air pollution is a phenomenon in which certain substances enter the atmosphere due to human activities or natural processes, present in sufficient concentrations for sufficient time, and thus endanger the comfort, health and welfare of the human body or the environment. Air pollutants enter the atmosphere from man-made or natural sources, participate in the circulation process of the atmosphere, and after a certain residence time, are removed from the atmosphere through chemical reactions, biological activities and physical deposition in the atmosphere. If the output rate is less than the input rate, it will be relatively concentrated in the atmosphere, resulting in an increase in the concentration of a certain substance ...
