[Abstract]

　To clarify carbon cycle in agricultural ecosystems at a regional scale, we established the method to clarify the carbon cycle in the regional ecosystem using Landsat TM data and made a map of its annual carbon flux. The study area was the basin of Koise River, Ibaraki Prefecture (30km x 30km). The annual flux varied from -493 to +40gC/m²/yr with an average of -151gC/m²/yr. Carbon budgets in croplands varied largely at a regional scale, suggesting that we must cover this spatial variation to estimate the regional carbon budgets.
