Abstract

The invention provides an allocation method and system for an atmospheric non-point source emission list. The allocation method comprises the following steps: firstly, collecting atmospheric non-pointsource emission list data, weight raster data, an administrative map and a time spectrum data file for a researched area; performing grid division operation on the administrative map, and loading theweight grid data to the gridded administrative map to obtain new weight grid data; performing de-unitization operation on the new weight raster data, and performing gridding calculation on the weightraster data and the atmospheric non-point source emission data to obtain gridding pollutant emission amount and complete space allocation operation; performing pollutant discharge distribution in different time periods by utilizing various time distribution coefficients in the time spectrum file and the gridding discharge after space distribution to finish time distribution operation; compiling aNetCDF file by utilizing the time-space information parameters and the gridding emission data; and finally, the manufactured NetCDF gridding data can be used for the input of an air quality model andthe visual operation of the NetCDF.

Description

technical field [0001] The invention relates to the technical field of environmental protection, and more specifically, to a distribution method and system for atmospheric surface source emission inventory. Background technique [0002] Recent studies have shown that domestic urban agglomerations show the characteristics of regional air pollution, and the pollutants emitted by atmospheric non-point sources have an important contribution to the total amount of air pollutants in the region. The spatial distribution of pollutant emissions from air pollution sources is one of the key steps in the preprocessing models of air quality models such as CMAQ. In the existing technology, the researchers mainly use the related GIS software under the Windows system to establish the emission inventory, but the GIS software does not have the function of compiling NetCDF files, so it is difficult to compare the emission inventory data established by themselves with the Linux system. Running...
