Abstract

Abstract:

The agricultural ecosystem is both a carbon source and a carbon sink, with strong potential for carbon sequestration and thus makes significant contributions to the global carbon cycle. The traditional small-scale and fragmented agricultural production pattern on dry slopes in the southwestern region have brought great uncertainty to regional carbon emissions. Exploring the characteristics of carbon emissions and reduction pathways on dry slopes in the southwest is of great significance for improving the environment and enhancing the potential of regional agricultural production. This study systematically summarized the production processes of major greenhouse gases (CO₂, N₂O, CH₄) in the agricultural ecosystem of dry slopes in the southwestern region of China. We discussed the effects of new materials and technologies application for carbon sequestration and emission reduction on dry slopes, and proposed carbon sequestration and emission reduction strategies for dry slopes in the future. (1) Given the significant differences in regional resources, industrial foundation, production scale, management methods, and ecological functions in dry slopes in the southwestern mountainous areas, suitable carbon sequestration and emission reduction measures and monitoring systems should be developed based on the specific agricultural production conditions of the region. The aim was to explore the carbon emission process and its underlying mechanisms in the context of global warming, and comprehensively enhanced the resilience of regional agricultural production to climate change. (2) Considering the high crop replanting index and fragmented spatial distribution of crops in the southwestern mountainous areas, agricultural production methods should be improved and industrial spatial layout should be optimized based on national strategies and local plans, aiming for an agricultural ecosystem with low carbon emission and high productivity. (3) As carbon emission reduction on dry slopes in the southwestern mountainous areas was a complex process, it was currently necessary to optimize and combine mature emission reduction technologies, carbon sequestration products, and carbon sequestration models in a targeted manner based on the actual structure and functional needs of regional agricultural production in the foreseeable future. This would form comprehensive carbon sequestration and emission reduction plans. In summary, this review hoped to provide a comprehensive and effective reference for further research on the carbon source and carbon sink characteristics of the agricultural ecosystem in dry slopes in the southwestern region, as well as for rational adjustment of farmland management measures.
