Abstract
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...
