Carbon Sink Effect of Plateau Grassland and Contribution of Carbon Cycle

Abstract

This paper reviews the research progress of plateau grassland carbon sink effect and its contribution and role to global carbon cycle. The paper also evaluates the size and change of plateau grassland carbon sink effect, and reveals its spatiotemporal distribution and dynamic characteristics. The paper discusses the relationship between plateau grassland carbon sink effect and global carbon cycle, and elucidates its role and significance in contributing to global carbon balance, mitigating global climate change, and protecting global biodiversity. The paper analyzes the positive and negative effects and interactions of climate change, human activities, grassland type and management on plateau grassland carbon sink effect, and proposes the influencing mechanism and mode of plateau grassland carbon sink effect. The paper points out the difficulties and shortcomings of the research on plateau grassland carbon sink effect, and puts forward some suggestions and prospects for future research. The paper aims to provide reference and inspiration for deepening the understanding of the internal mechanism and external influence of plateau grassland carbon sink effect, and for formulating effective grassland protection and management measures.
