COUPLING OF VAPOR AND CARBON FLUX IN CONIFEROUS AND BROAD-LEAVED MIXED FOREST ECOSYSTEM IN DINGHUSHAM

摘要

Radiation, latent heat/water vapor, sensible heat, soil heat fluxes and meteorologic factors, such as temperature, relative humidity, wind speed and precipitation in the coniferous and broad-leaved mixed forest in Dinghushan Mountain, South China, were monitored by an Open Path Eddy Cvariance (EC) system and RMET System in 2003. The reliability and the influence of modified processes of EC fluxes data were analyzed. The temporal and spatial distribution of water vapor, heat fluxes and relative meteorologic factors were discussed. The application of measured and calculated methods to fluxes in mountainous forest ecosystem were discussed. The results were given as followings:
