中国草地固碳减排研究现状及其建议

随着经济的快速发展，温室气体的排放量不断增加，加之人类对自然资源的利用强度逐渐增加，导致全球生态系统的固碳能力减弱，大气中的温室气体浓度达到新高，所造成的温室效应已经成为国际社会普遍关注的重大全球性问题。中国草地碳汇资源得天独厚，发展草原碳汇经济成为履行国际承诺、打造碳汇新经济、建设美丽中国的重要载体。综述中国草地固碳减排现状及其影响因素，包括草地碳汇和家畜生产减排研究、气候变化背景下的草地碳汇、人工草地建设等方面，并提出中国草地固碳减排发展建议，以期为中国实现碳达峰、碳中和及草地固碳减排的贡献提供理论基础，为推动我国社会高质量发展、创造高品质生活提供坚实的技术支撑。

Research status and suggestions for grassland carbon sequestration and emission reduction in China

With rapid economic development， and continuing increase in the emission of greenhouse gases， coupled with intensification of human use of natural resources， the carbon sequestration capacity of the global ecosystem has weakened， and the concentration of greenhouse gases in the global atmosphere has reached a new high. This has become a major global issue of general concern to the international community. China’s grassland carbon sink resources are unique， and the development of the grassland carbon sink economy has become an important vehicle for fulfilling international commitments， creating a new carbon sequestration economy and building a beautiful China with regenerative food production systems. This study reviews the current status of grassland carbon sequestration and emission reduction in China and the factors influencing sequestration， including research into grassland carbon sink capacity and reduction of emissions linked to livestock production now that there is a background of climate change and establishment of sown artificial grassland construction. Our review proposes a plan for the development of grassland carbon sequestration and emission reduction in China and provides a theoretical basis for contribution to carbon neutrality， and carbon sequestration and emission reduction in China’s grasslands.
