Embodiment Construction

[0026] The present invention provides a method for accurately calculating the emission of aviation air pollutants in the airspace. The method can be applied to the establishment of the aviation pollution discharge inventory in the airspace, and is helpful for further analysis of the main factors affecting the emission of aviation air pollution. Regional cooperation to control pollution will provide a basis for the future implementation of the regional compensation system and the emission trading system.

[0027] In order to achieve the above object, the invention provides a method for measuring the emission of air pollutants from aviation, comprising

[0028] 1) Define the scope of the research airspace according to the spatial extent of the flight information region and the information of the exit / entry waypoints;

[0029] 2) Establish a flight database in the airspace: including flight number, takeoff and landing airport, planned flight route, flight distance, all waypoints ...

Abstract

The invention relates to a method for determining the discharge amount of aviation atmospheric pollutants based on a spatial domain scale. The method mainly comprises the following steps: 1) definingthe range of a research spatial domain; 2) establishing a flight database in the airspace, wherein the flight database comprises flight numbers, take-off and landing airports, flight distances, flightroutes, waypoints, passenger carrying rates and models; 3) establishing a model and engine database; 4) dividing all airlines of the researched airspace into two types of an intra-region airline anda cross-region airline; And 5) calculating the discharge amounts of atmospheric pollutants NOx, HC, CO, CO2 and SOx generated by all airlines in the research airspace according to the model. The invention provides a calculation method for accurately measuring the discharge amount of the aviation atmospheric pollutants in different research airspaces, different types of atmospheric pollutants are comprehensively considered, the discharge responsibility of the aviation atmospheric pollutants in different airspaces is conveniently defined, and the aviation atmospheric pollution is further treatedfrom the regional scale.

Description

technical field [0001] The invention relates to a method for measuring the emission of aviation air pollutants based on the airspace scale. Background technique [0002] In the research field of aviation air pollutant emissions, most studies focus on the pollution emissions at the airport and airline scales, while there are few methods for calculating aviation pollution emissions at the airspace scale. Previous methods often use simplified calculation methods to directly calculate the air pollutants emitted by all routes departing from airports in the airspace during the entire voyage, regardless of which flight segments are in the airspace and which flight segments are not in the airspace. Therefore, it is difficult to accurately measure aviation air pollution emissions in the airspace. Contents of the invention [0003] According to one aspect of the present invention, there is provided a method for measuring the emission of aviation air pollutants based on the airspace...
