Abstract

The invention provides a multi-scale air quality space interpolation method, system, medium and equipment. The method comprises: step 1, according to the area of a target area, the number of air quality monitoring stations and air quality monitoring data as source data, a nearest neighbor interpolation algorithm is used for carrying out interpolation estimation on the air quality of an area, not covered by the air quality monitoring stations, in the target area, and first air quality interpolation is obtained; and step 2, processing the first air quality interpolation by adopting a radial basis function interpolation algorithm to obtain a second air quality interpolation. According to the method, the sparse point source data can be reasonably and finely subjected to spatial interpolation processing, and parameters can be adaptively adjusted according to different urban areas and air quality monitoring point distribution, so that the practicability of the method is further improved.

Description

technical field [0001] The invention relates to the field of spatial interpolation algorithms, in particular to the research on urban air quality spatial interpolation methods facing sparse point sources. Background technique [0002] In recent years, the rapid and stable economic development has greatly improved the quality of life of our people. But at the same time, it also brings a series of environmental problems. Regional fog and haze weather is a typical representative of such problems. This type of weather seriously affects the visibility of the atmosphere and endangers the health of the public. One of the topics of people's livelihood that is getting more and more attention. Real-time release of air quality status to the public, effective analysis of the distribution characteristics of air pollutants that affect air quality, and timely early warning and control of the occurrence and continuous spread of air pollution are important links to solve current problems. ...
