Abstract: Grasslands are the important ecosystems and natural resources,which play a fundamental and strategic role in China's ecological security. The thriving prosperity of grasslands shall lead to the prosperity of forests and grasslands,the thriving prosperity of forests and grasslands shall lead to the prosperity of ecological environments,and the prosperity of ecological environments shall lead to the prosperity of civilization. In 2020,China brought up the goal of achieving carbon emission to peak by 2030 and carbon neutrality by 2060. The "Carbon peaking and carbon neutrality" goal has already put forward the higher requirements to grassland ecological protection and restoration,also created a historic opportunity for comprehensively strengthening grassland managements. In order to fully serve to the overall situations of China's response to climate change,in this paper the opportunities about and problems at grassland sink enhancement were analyzed,and it was proposed some approaches about the grassland sink enhancement,such as bringing artificial plantation of grasses up,strengthening of the grassland protection,restoration and management,continuing the improvements of grassland ecological quality,developing the high-quality modern grassland industry,strengthening of the supports and supply guarantees,and boosting of the social publicity about and training for the grassland sciences. The overall aim in the paper was set to provide a reference for grassland to support the "Carbon peaking and carbon neutrality" goal being in reality.

摘要： 草原是我国重要的生态系统和自然资源,对国家生态安全具有基础性、战略性作用。草原兴则林草兴,林草兴则生态兴,生态兴则文明兴。2020年,我国提出了"2030年前实现碳达峰,2060年前实现碳中和"的目标。"双碳"目标的提出,对草原生态保护修复提出了更高的要求,也为全面加强草原治理工作创造了历史性机遇。为全面服务国家应对气候变化工作大局,文章分析了当前草原增汇面临的机遇和存在的问题,提出了大力开展人工种草、加强草原保护修复和管理、持续提升草原生态质量、高质量发展现代草业、强化支撑保障、加大社会宣传培训力度等草原增汇路径,旨在为草原助力实现"双碳"目标提供参考。
