高尔夫球场的氮磷环境及其流出特性

The nitrogen and phosphorus environment and its effusion characteristics in golf course

调研日本小野田高尔夫球场结果表明：球场土壤中总氮（TN）和总磷（TP）主要存在于土表,其含量分别为2 190 mg/kg和1 270 mg/kg.溶出实验显示：酸性条件、适宜温度及长时间的溶解状态对土壤中氮、磷溶出有明显促进作用.高尔夫球场土壤空隙中N、P对地下水质不会造成显著影响,降雨时地表流出TN的浓度超出环境标准,流出TP的浓度超出环境标准的7～15倍,是地表水的潜在污染源之一.

The investigation and measurements in the Onoda golf course （Japan） showed that the Total Nitrogen （TN） and Total phosphorus （TP） mainly existed in the surface of the soil. The concentrations of TN and TP in the course were 2 190 mg/kg and 1 270 mg/kg, respectively. Dissolving experimental results indicated that the acidic condition, suitable temperature as well as long time dissolving condition had obvious promoter action for the nitrogen and phosphorus dissolving in soil. Results showed that the Nitrogen and phosphorus in soil pore-water had no remarkable influence on the groundwater quality. However, the concentration of TN in the draining water exceeded the environmental standard, and the TP exceeded the environmental standard 7-15 times. Therefore the draining water is the potential pollotion source of the surface water.
