Energy balance and evapotranspiration in broad-leaved Korean pine forest in Changbai Mountains
摘要
Abstract
Based on the continuous measurements of an open-path eddy covariance system, this paper analyzed the characteristics of energy balance components and evapotranspiration in a broadleaved Korean pine forest in Changbai Mountains in 2008. as well as the differences of energy balance components and evapotranspiration between growth season and dormant season. For the test forest, the year-round energy balance closure was 72％ , being at a medium level, compared to the other studies in the Fluxnet community. The energy balance components had significant differences in their diurnal and seasonal variations. In growth season. turbulent energy exchange was dominated by upward latent heat flux, accounting for 66％ of available energy; while in dormant season. the turbulent energy exchange was dominated by upward sensible heat flux. accounting for 63％ of available energy. The accumulated annual evapotranspiration in the study site in 2008 was 484.7 mm, occupying 87％ of the precipitation at the same time period (558.9 mm) . which demonstrated that evapotranspiration was the main water loss item in temperate forests of Northern China.关键词
