Research on carbon emissions and its influencing factors in Chinese lakes
This article comprehensively analyzes the carbon emissions and influencing factors of Chinese lakes,emphasizes the important role of lakes in carbon cycling,and focuses on the research progress of lake carbon emissions.Currently,the annual CO2 and CH4 emissions fluxes of Chinese lakes are 6.22～8.07 Tg C and 1.41 Tg C,respectively.At the same time,the influencing factors of lake carbon emissions fluxes are clarified.This article summarizes the current methods for estimating lake carbon emissions flux,indicating the enormous potential of satellite remote sensing monitoring in estimating lake carbon emis-sions flux.Key research directions for future remote sensing estimation of lake carbon emissions flux in-clude further analysis and integration of existing remote sensing and ground monitoring data,improving da-ta accuracy and reliability,developing new numerical models,and strengthening the development and ap-plication of mechanistic models.This study emphasizes the complex interaction of ecological,geograph-ical,and meteorological factors in influencing lake carbon emissions,which is of great significance for a deeper understanding of lake carbon cycling and management of lake carbon emissions.
