摘要: |
平原感潮河网地区非点源污染严重,由于具有交叉污染等特性,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。构建了大尺度非点源污染负荷匡算模型,对南通平原河网地区非点源污染负荷进行了匡算。根据不同的产污方式,将非点源污染分为城镇降雨径流污染、畜禽养殖污染、农田降雨径流污染、农村生活污染和水产养殖污染等5种类型,分别计算其流失过程。 |

Estimation of Non-point Source Pollution Load Plain Tidal River Networks |
|
Abstract: |
The non-point source pollution in plain tidal river networks is serious.There is a serious environmental pollution problem in plain river networks for its intersectatant pollution.The study designed a large-scale to estimate the non-point source pollution load in Nantong.There were five types of different pollution modes such as municipal and town runoff,livestock and poultry raising pollution,paddy field runoff,rural domestic sewage,fish breeding pollution. |
Key words: plain tidal river networks polder areas plain areas estimation of non-point source pollution load |
