| 摘 要： | 平原感潮河网地区非点源污染严重,同时由于本身具有的交叉污染等特性,造成了整个平原河网存在严重的环境污染和环境安全问题。文章在南通平原河网地区选择圩区作为典型区,以野外观测和室内分析相结合的方法开展野外原位试验,研究平原河网典型圩区各形态污染物随降雨径流的迁移特征,建立了稻季农田营养盐的迁移通量与径流通量、施肥量及降雨距施肥时间间隔三者之间的定量化关系。

| Abstract: | The non-point source pollution in plain tidal river networks is serious,at the same time,for its intersectant pollution,plain rever networks exists serious environmental pollution porblem.A typical agricultural watershed and runoff plots in polder areas in Nantong was selected and experiment in situ was conducted in this study. The transportation characteristics of various forms nutrients drived by natural rainfall-runoff were studied by field observations and laboratory testing. Regression relationships between transportation fluxes with runoff fluxes and fertilization were set up. |
