Nitrogen concentration of stream waters and landuse in the agricultural areaThe relations between NO3-n concentration and landuse were investigated in Hokkaido areaHigh concentration of NO3-N were measured in the ground water under the vegetable field in Kanto areaNitrogen removal in paddy fieldsNitrogen removal were measured in paddy fieldsThe effect of NO3-N concentration and temperature on nitrogen removal were investigated, and the equation of nitrogen removal was introduced

农业区溪流水体氮浓度与土地利用情况调查北海道地区NO3-n浓度与土地利用的关系，关东地区菜地下地下水测得高浓度NO3-N水田脱氮量测定稻田脱氮量调查NO3-N浓度和温度对脱氮效果的影响，计算公式为 引入脱氮
