It was generally understood that the evaluation of pollutant loads make a difference with each basin, and land use, so it was considered that estimation of pollutant loads a using the result of investigate could be exactly estimated for a pollutant loads. We had been investigated the pollutant loads of young forest watershed and forest basin in the upstream basin of Tone river, made use of result of investigation for the pollutant loads. Pollutant loads factor of the forest area or skiing ground had been estimated as following. The point source was left out of the total pollutant loads of discharge in mountainous forest basin. Pollutant loads factor of young forest area were estimated directly a using the result of investigation. We discussed in relation to the investigation of pollutant load factors, results in which were shown as following. Result of evaluation pollutant factors on forest was compared with bibliographic correctly. T-N pollutant factor of skiing ground was one-fifth time as compared with bibliographic golf course, COD was about half. Evaluated T-N pollutant factor was about one-sixth time as compared with bibliographic in the young forest.
