模拟状态下高尔夫球场果岭区域土壤氮磷浸出物对铁岗水库水质影响研究

通过采集高尔夫球场即将淹没的果岭土壤进行实验室条件下的模拟库基样品试验,对水库扩容后蓄水初期水质的变化情况进行了研究.结果表明:库水所含主要成分pH、高锰酸钾盐指数、总氮、总磷、氨氮和硝酸盐氮分别为7.4(mg/L)、30.8(mg/L)、1.16(mg/L)、1.189(mg/L)、0.21(mg/L)和0.11(mg/L);果岭20 cm土层库基土样pH、有机质、硝酸盐氮、氨态氮和有效磷分别为6.41(mg/kg)、10.29(mg/kg)、25.48(mg/kg)、25.76(mg/kg)和140.77(mg/kg).现有库基成分会改变库水高锰酸钾盐指标的升高.库水本身的总磷和总氮含量就严重超标.果岭库基本身的磷氮含量也很高.浸泡后果岭库基土样对降低浸出物总磷的严重超标起到了对冲的作用,致使总磷含量大为降低.

Influence of Nitrogen and Phosphorus Extractives in Golf Course Soils on Water Quality of Tiegang Reservoir

Through collecting samples in the stadium simulation submerged of green golf under laboratory conditions, the changes of water quality in the initial stage of the expansion of the reservoir are studied. The results shows:the water contains in the main component of the pH, Potassium Permanganate salt index, total nitrogen and total phosphorus, ammonia nitrogen and ni-trate nitrogen are 7. 4(mg/L),30. 8(mg/L),1. 16(mg/L),1. 189(mg/L), 0. 21(mg/L)and 0. 11(mg/L). The soil samples' pH, organic matter, nitrate nitrogen, ammonia nitrogen and available phosphorus are 6. 41(mg/kg),10. 29(mg/kg),25. 48(mg/kg),25. 76(mg/kg)and 140. 77(mg/kg). Existing ingredients change the water's Potassium Permanganate salt index. The total phosphorus and total nitrogen content of water is seriously overweight. The content of phosphorus and nitrogen in the green base is also very high. After soaking, the green base causes the total phosphorus content is greatly reduced.
