Abstract

The invention provides a location selection method of PM2.5 new mobile station based on Kriging interpolation, which comprises pre-analysis of initial data, including pre-treatment of PM2.5 concentration data of set monitoring stations, distance statistics between stations and division of research area grid, and each grid is taken as an alternative station. Selection of the data of several monitoring stations at a certain time in the study area and choosing the best variogram function model to calculate; Calculation of the prediction value of PM2.5 concentration of each grid, calculation of the Kriging estimation error variance of each grid, calculation of the Kriging estimation error variance of all candidate grid stations in the study area and divide the Kriging estimation error varianceinto grades for comparison; Calculation of the overall regional variance after adding different levels of alternate grid sites. The monitor station is densified, the location optimization is carry out from the angle of the newly added mobile station, and the PM2.5 concentration information with more accurate estimation of the monitoring station is utilized, and the atmospheric pollution prevention and control work is more effectively carry out.

Description

technical field [0001] The invention belongs to the technical field of spatial analysis of geographic information, and relates to a method for selecting the location of a PM2.5 new mobile station based on kriging interpolation. Background technique [0002] When monitoring and managing the PM2.5 concentration near the ground in the city, it is necessary to obtain and analyze the PM2.5 concentration data through ground monitoring stations, so as to provide a reliable basis for PM2.5 concentration control and management. However, with the increasingly prominent contradictions of atmospheric environmental protection and the urgent need for PM2.5 research, the shortcomings of the monitoring station network itself are increasingly revealed. Under ideal conditions, the more monitoring points and the wider the distribution, the more complete the information reflected, but the layout, operation and maintenance of PM2.5 monitoring sites require a lot of manpower, material and financi...
