| Research Abstract |
A terrestrial ecosystem model was developed for East Asia with high resolution (0.5°×0.5°grid size). Results were compared with nationwide population density and human activities. It was clarified that P/R ratio has become lower than 1.0 at moment in Japan, China and India resulting an increase in emission of green house gases in the 21 century.
During this three years the field observations together with the stable isotope methods, satellite remote sensing, and modeling were conducted simultaneously to refine the above mentioned conclusions.
