The Dynamic Land Ecosystem Model (DLEM)

Slide1

The simplified framework of the DLEM for simulating  carbon, nitrogen and water fluxes and pools of terrestrial ecosystems (Tian et al. 2010; Pan et al. 2014)


                

      The Dynamic Land Ecosystem Model (DLEM) is a highly-integrated process based ecosystem model that aims at simulating the structural and functional dynamics of land ecosystems affected by multiple factors including climate, atmospheric compositions (CO2, nitrogen deposition, and tropospheric ozone), land use and land cover change, and land management practices (harvest, rotation, fertilization etc). The DLEM has five core components: 1) biophysics, 2) plant physiology, 3) soil biogeochemistry, 4) dynamic vegetation, and 5) land use and management. The model operates at a daily time step with spatially explicit information on climate, vegetation and soils to provide estimates of carbon, nitrogen and water fluxes and pools of terrestrial ecosystem from site to regional to global scales.
