Abstract

The invention provides a method for preparing an emission inventory of road dust sources with high temporal and spatial resolution. The method includes: Step 1: Obtain high-resolution remote sensing images, geographic videos, real-time traffic data and road dust observation data, and obtain multi-source spatiotemporal data of urban road dust influencing factors in the target area based on the collected data perception; Step 2: Based on Said multi-source spatio-temporal data, build road dust load spatial distribution model, traffic condition spatial distribution model, and localize road dust emission factor model; Step 3: Construct road dust load spatio-temporal database, road dust activity level spatio-temporal database and the road dust emission factor spatio-temporal database; step 4: according to the road dust activity level spatio-temporal database, the road dust emission factor spatio-temporal database and the road dust load spatio-temporal database, calculate the road dust emissions of different road sections at different times , to realize the compilation of emission inventory of road dust sources with high spatio-temporal resolution.

Description

technical field [0001] The invention relates to the technical fields of geographic information and resources and the environment, and can be used for air quality numerical simulation, air pollution prevention and control, and fine air quality management, and in particular relates to a method for preparing an emission list of road dust sources with high temporal and spatial resolution. Background technique [0002] In a specific area, based on the dual goal constraints of improving the accuracy of the road dust emission inventory and reducing the cost of road dust emission inventory, how to use the high-resolution road dust emission inventory in a specific area, combined with numerical simulation to accurately simulate Air quality has become a fundamental issue in the refined management of air quality. [0003] From the point of view of the method of compiling the emission inventory, it mainly includes top-down (Peng Kang, Yang Yang. Study on dust emission factors and emissio...
