摘要
水环境面源污染的严重性已受到国内外普遍关注,面源污染业已成为国际上水环境问题研究的活跃领域。本文以宁武县恢河流域作为研究对象,在对恢河流域面源污染现状进行资料收集和数据分析的基础上,从面源污染的发生机理和面源污染的特点出发,分析面源污染与水体环境之间的关系,并探讨了农业面源污染对水环境的影响,并对宁武县恢河流域的面源污染现状进行判断并提出相应对策,为改善宁武县恢河流域水体质量,保护生态环境提供科学依据。
The ponderance of diffuse pollution in water environment has been attentioned to generally,and the diffuse pollution was already the active field for the research on the problem of water environment in the world.Taking Hui river watershed in Ningwu county as the study area,this paper started from the occuring mechanisms and the characteristics of non-point source pollution,and analyzed the interrelation between non-point source pollution and the water environment,discussed the influence of non- point source pollution on the water environment based on the data collection and data analysis of the current situation of diffuse pollution in the river basin,and determined the non-point source pollution in Hui river watershed in Ningwu county,finally put forward to the corresponding countermeasures.The study can provide scientific basis for the improvement of water environment quality and the protection of the ecological environment in Ningwu County.
