Abstract

The invention relates to the regional spatial quality analysis related technical field, and especially relates to a regional spatial quality analysis method. The method comprises the following steps of: meshing a region, and determining the longitude and latitude coordinate of each mesh center point; obtaining atmospheric environment monitoring data of each single time slice; determining an influence point searching range by using each mesh center point as an interpolating point; searching influence sample points in an influence point searching range by using monitoring sites as influence points, and determining the weight value of each influence sample point; performing interpolating calculation on each interpolating point by a pollutant concentration monitoring value of the corresponding influence sample point according to the corresponding weight value, so as to obtain the concentration interpolating result of the mesh center point corresponding to each interpolating point. The regional spatial quality analysis method provided by the invention is suitable for small and medium size regional air quality spatial analysis, guarantees the rapid calculation speed and the high interpolating precision, and provides accurate and visual regional pollutant spatial distribution information for the public.

Description

technical field [0001] The invention relates to the technical field of space quality analysis, in particular to a method for analyzing regional space quality. Background technique [0002] Environmental issues have become one of the most severe challenges facing human development today. Environmental protection departments have invested a lot of manpower and material resources in the maintenance of environmental monitoring equipment, but they are still exhausted. Atmospheric environmental monitoring stations in various places are usually discrete, uneven, and limited in number. They directly use the method of marking data on each station. The display speed is fast and the data is accurate. However, the display of regional air quality is not intuitive enough, and it is only expressed from a large amount of data. It is difficult to quickly find out the key pollution areas. Using limited atmospheric monitoring stations for spatial analysis to intuitively reflect the distribut...
