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.

建立了东亚陆地生态系统高分辨率（0.5°×0.5°网格尺寸）模型。结果与全国人口密度和人类活动进行了比较。据了解，目前日本、中国和印度的P/R比率已低于1.0，导致21世纪温室气体排放量增加。在这三年中，实地观测与稳定同位素方法、卫星遥感和模拟同时进行，以完善上述结论。
