| Research Abstract |
In this research, the different database of population, land use, social statistics, etc., was collected and created using the same format for 21 century . The temporal and spatial distribution of the nitrogen, phosphorus, and soil sediment was mapped for Japan. The simulation of the long term water environment loadings was conducted then. To validate the simulation results, the river basins in Japan were selected for calculation. Finally, the trend and causes of nitrogen and sediment loadings were evaluated based on the above results.
