Abstract:?In this study, the ecosystem of subtropical evergreen broad-leaved forest in Ailao Shan was taken as the research object, and the long-term positioning observation of carbohydrate flux in subtropical evergreen broad-leaved forest ecosystem was carried out by using vorticity correlation technology. Ailao shan Ecological Station, as the national field station and the basic observation station of China Ecosystem Research Network, has continuously accumulated 12 years of standardized data sets of carbohydrate flux and key meteorological elements in subtropical evergreen broad-leaved forest based on China FLUX data processing system. This data set can provide data support for us to evaluate the contribution of ecosystem to climate change, predict the global regional climate change trend, develop subtropical evergreen broad-leaved forest ecosystem carbon and water flux exchange characteristics, subtropical evergreen broad-leaved forest ecosystem structure, function, the material and energy cycle, the sustainable utilization of biological resources, and the regional carbon budget management policy of climate change.
