Problems solved by technology

[0004] In the existing emission inventory allocation methods, due to the difficulty in obtaining land use type data, the spatial allocation of traffic source pollution using only road network data ignores the traffic conditions in different regions, and the commonly used population density data mostly use land use data and nighttime Lighting index, the data has a certain lag, low accuracy and poor timeliness

Abstract

The embodiment of the invention provides an air pollutant emission inventory space allocation method and a device based on a POI (Point of interest). Mesh dividing is carried out on a target area ready for the air pollutant space allocation. As for each mesh, POIs of corresponding pollution sources are counted; an allocation parameter of a pollutant in the area of the mesh is obtained through calculation of the POI, and the pollutants in the area of the mesh are calculated according to the allocation parameters. Compared with the traditional pollutant allocation method, due to the accuracy, the timeliness, the easy acquisition and the information richness of the POI data, a POI-based method is adopted to obtain pollutant allocation, reasonable space allocation can be carried out on non-point source pollution, and an air pollutant emission inventory with higher accuracy can be obtained.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a POI point-based air pollutant discharge inventory space allocation method and device. Background technique [0002] The air pollutant emission inventory is a list of the quantities of various pollutants emitted into the atmosphere by pollution sources within a certain time span and space area, and making an air pollutant emission inventory with high temporal and spatial resolution can provide a basis for air quality management and numerical simulation. Basic data. At present, the compilation of air pollutant emission inventory with high temporal and spatial resolution is mainly based on the spatial geographic information of different pollution sources, and the emission inventory data is spatially gridded on a spatial scale of 3km×3km or 1km×1km to obtain high spatial resolution. According to the time emission characteristics of pollutants from diff...
