The invention discloses a water-soil-energy comprehensive management oriented agricultural greenhouse gas evaluation method, which utilizes a water-soil-energy-grain coupling principle to meter greenhouse gas emission produced by crops, and analyzes and improves an adjustable greenhouse gas emission source according to a calculation result to reduce greenhouse gas emission. According to the evaluation method provided by the invention, energy exploitation and transportation, chemical fertilizer production and transportation, irrigation, rice field methane and nitrogen fertilizer application andthe like are determined as agricultural greenhouse gas emission sources; agricultural greenhouse gas emission is evaluated from the aspects of source exploitation and transportation, chemical fertilizer production and transportation, irrigation, rice field methane and nitrogen fertilizer application and the like, evaluation is more comprehensive and accurate, and water-soil-energy comprehensive management of agricultural greenhouse gas is achieved. Furthermore, the greenhouse gas emission condition can be intuitively known from the aspects of energy exploitation and transportation, chemical fertilizer production and transportation, irrigation, rice field methane and nitrogen fertilizer application and the like; as an effective basis for reducing greenhouse gas emission by improving adjustable factors in later-period management, for example, greenhouse gas emission can be reduced by improving a crop planting structure, optimizing the fertilization rate, improving the water resource utilization efficiency, controlling underground water level drop, increasing the renewable energy source proportion, improving the methane recovery rate and the like.
Description
technical field [0001] The invention belongs to the field of greenhouse gas emission reduction, and in particular relates to an agricultural greenhouse gas assessment method oriented to water-soil-energy comprehensive management. This method uses the water-soil-energy-grain coupling principle to measure greenhouse gas emissions from crop production. Background technique [0002] The agricultural sector produces 17-34% of global anthropogenic greenhouse gas emissions while meeting human food consumption needs. The demand for food will continue to increase in the future. How to reduce greenhouse gas emissions on the premise of ensuring food production is a huge challenge facing the world. Agricultural production involves multiple sectors and depends on inputs of material materials such as water, fertilizers, and energy. From the perspective of life cycle, multi-sectoral collaborative management will have a more ideal effect on agricultural greenhouse gas emissions. However,...
