Review on Greenhouse Gas Mitigation and Carbon Sink in Agroecosystem

Globally, mankind is facing an increasingly severe challenge of climate change, and the vast majority of countries are making sustained efforts to solve the problem. Agroecosystem is not only an important source of greenhouse gas emissions, but also has a large potential of carbon sink, so research on greenhouse gas mitigation and carbon sink in agroecosystems is an important initiative to address the challenge of climate change. However, the current domestic research on carbon sinks mainly focuses on forests, grasslands and oceans, and there are relatively few studies on carbon sinks in agroecosystems. Studies on greenhouse gas emission reduction is also mainly concentrated in the fields of industry, energy and lacks the attention in the field of agriculture. Therefore, the research on greenhouse gas mitigation and carbon sink in agroecosystems needs to be carried out urgently. This paper systematically reviewed the research progress to reduce greenhouse gas emissions and increase carbon sinks in agroecosystem, and focused on the role of a series of agricultural management measures, such as agricultural waste disposal, fertilizer management and soil improvement in reducing emissions and increasing sinks in agroecosystem, and put forward relevant suggestions and prospects for the measures to reduce emissions and increase sinks in agroecosystem and the future research direction, with a view to providing useful reference for agricultural practice and realize green and sustainable agricultural production.
