ABSTRACT

Napahai, located on the plateau of northwestern Yunnan, is a highly sensitive ecosystem. Based on existing research data, this paper analyzes the potential impact of regional temperature rise on CO₂ emissions from this wetland. By synthesizing key indicators such as temperature change trends, vegetation photosynthetic and respiratory responses, litter decomposition rates, and soil carbon pool dynamics, a comprehensive impact assessment framework was constructed. The results indicate that with rising temperatures, although plant photosynthesis is enhanced, the significant acceleration of litter decomposition rates and the increased volatility of soil carbon stocks may collectively lead to an overall increase in CO₂ emissions from the wetland, posing a risk of weakening its carbon sink function.
