江西省各县市农业非点源氮潜在负荷分布特点

Agricultural non-point source nitrogen latent load in Jiangxi Province

随着人类经济活动的深入,水污染已经成为全球性的问题。经调查发现水质污染的主要原因是农业非点源污染。近年来农业非点源污染已经成为环境污染研究的热点,但是江西省非点源氮污染估算及分布研究还是空白,本文利用输出系数模型估算出江西省各县市的氮潜在负荷量,并分析其非点源污染的特点。

With the development of hunman economic activities, water pollution is one of global problems, and the main reason is the polluion of agriculture non-point source （NPS）. And it has become the focus of attention between scientists, but there is nothingness about the study of estimation and distrubution of agriculture NPS in Jiangxi Province until now,and the this arctle estimates Nitrogen Latency Load in the counties by export coefficient modeling,and analyzes the spatial-temporal distribution character.
