| 摘 要： | 农业非点源污染已成为当前影响水体环境质量的主要因子之一,对农业非点源污染控制措施的研究十分迫切和必要。青铜峡灌区农业非点源污染研究和相关监测试验表明,水分是当地农业非点源污染物产生和迁移的主要动力和载体,灌溉过程中应当加强田间水分管理,实施节水灌溉和控制排水,为改善田间土壤养分结构,强调实行和推广田间测土配方施肥技术。农田排水沟渠在输送农田排水的同时具有人工湿地的生态功效,可以充分利用生态工程技术降解吸附农田排水中的污染物,避免污染外界水体。 |
| 关 键 词： | 农业非点源污染 节水灌溉 控制排水 配方施肥 生态工程 |

| Abstract: | Recently,along with the highlighted water environmental issues and relatively improving control standards of the point source pollution,non-point source pollution(NSP),agricultural non-point source pollution problem especially caused by heavy use chemical fertilizers and pesticides has aroused great concern and attention.Thus,the research on control measures of agricultural non-point source pollution has been an extraordinarily exigent problem.This paper,taking the Qingtongxia Irrigation District at the Yel... |
