A Spatial Gridding Method for Carbon Dioxide Emissions in the Transportation Sector

Abstract

The invention relates to the technical field of greenhouse gas emission lists and space gridding management, in particular to a carbon dioxide emission space gridding method for traffic departments, which comprises the following steps: establishing a grid data model containing a plurality of grids, each grid corresponding to a unique grid ID; according to a carbon dioxide emission list method of atraffic department, obtaining the carbon dioxide emission amount of each traffic type in a certain area; respectively spatializing the carbon dioxide emission amount of each traffic type in the areainto a corresponding grid, and performing corresponding spatial analysis to obtain the total carbon dioxide emission amount of each traffic type and a corresponding grid ID; summarizing the grid IDs corresponding to the carbon dioxide emission of different traffic types spatially, carrying out spatialization processing, and obtaining the total carbon dioxide emission of different traffic types inthe area; and completing meshing of the carbon dioxide emission space.

Description

technical field [0001] The invention belongs to the technical field of greenhouse gas (carbon dioxide gas) emission inventory and spatial grid management, and in particular relates to a carbon dioxide emission spatial grid method for transportation departments. Background technique [0002] Establishing spatial grid data of greenhouse gas emissions with high spatial resolution, and based on this, establishing small-area emission inventories and studying the spatial characteristics of emissions is a focus and hotspot of international research. At present, existing technologies have been established from bottom to top A relatively mature greenhouse gas emission method system and spatial grid have been developed. [0003] Since the transportation industry involves many modes of transportation, such as roads, railways, water transportation, and aviation, the development of spatial grid methods for greenhouse gas / carbon dioxide emissions is relatively slow. However, its existing...
