Technical method for multi-scale monitoring and tracking of methane emission of livestock farm

The invention relates to the technical field of environment monitoring, in particular to a technical method for multi-scale monitoring and tracking of methane emission of a livestock farm. Arranging gas sensors on a plurality of spatial scales of the farm, wherein the gas sensors comprise a whole-farm scale, a regional scale and an individual scale; constructing a learning model; collecting methane concentration data on each spatial scale through a gas sensor; processing and analyzing the collected methane concentration data; the trained machine learning model is applied to real-time data monitoring, according to processing and analysis results, the trend of methane emission is identified, methane emission of a farm is predicted, control and emission reduction data of corresponding measures are selected, and monitoring and tracking result data are output; and monitoring and tracking result data are displayed in a visual manner, so that multi-scale monitoring and tracking of methane emission of the livestock f
