| 摘 要： | 为研究都市农业区域非点源磷污染对地下水的影响,选择上海市南汇区新场镇果园村的地下水为研究对象,并于2009年7月到9月雨季对该区域地下水进行连续监测。研究结果表明:该区域地下水中磷的形态以水溶性有机磷为主,水溶性总磷含量介于0.75～1.97mg/L之间,平均浓度为1.31mg/L,磷酸盐浓度在0.22～0.62mg/L之间,平均浓度为0.42mg/L。水质低于地表水Ⅴ类标准(0.4mg/L),地下水污染水平已严重超标,不宜饮用。地下水中非点源磷的迁移与土地利用类型相关,果园旁地下水中磷素浓度在降雨前后变化明显。同时,降雨时地表径流加剧磷素流失,农田施肥、水体渗漏均会加剧地下水磷素非点源污染。 |
| 关 键 词： | 都市农业区域 地下水 非点源污染 磷含量 |

| Abstract: | In order to research the effect of phosphorus non-point source pollution on groundwater in urban agricultural region,we study the phosphorus change on groundwater in Orchard Village,Nanhui District,Shanghai..The sample and monitor time was from July to September in 2009. The result showed that the water-soluble organic phosphorus was the main form of phosphorus,the concentration of total phosphorus and phosphate was respectively from 0.75 mg/L to 1.97 mg/L and 0.22 mg/L to 0.62 mg/L,with an average concentr... |
