潍坊市农业面源污染评价及控制对策

Evaluation and Control Strategies of Agricultural Non-Point Source Pollution in Weifang City

运用清单分析法、等标污染负荷法、等标污染指数法和聚类分析法等方法,对潍坊市农业面源污染进行了综合分析与评价.结果表明,2012年潍坊市农业面源污染COD、TN、TP的排放量分别为154273.13t、58449.77t、9664.82t,污染物排放总量最高的地区为诸城市;识别出全市最主要的污染源为畜禽养殖,最主要的污染物为TN.4种污染源等标污染指数以畜禽养殖最高,高密市的总等标污染指数最高,达到93.52,其次是昌乐县、寿光市和昌邑市.畜禽养殖污染是全市农业面源污染中贡献率最大的类型.最后,针对污染现状及不同污染类型,提出了一些针对性的控制对策.

Inventory analysis,equivalent standard load,equivalent standard pollution index,and cluster analysis methods were used to analyze and evaluate ANPSP of Weifang city.The results showed that the COD,TN and TP load of Weifang city were 154273.13 t,58449.77 tand 9664.82 tin 2012,the total load was the highest in Zhucheng city.The most important pollution source was from livestock and poultry breeding while the most important pollutant was TN.Livestock and poultry breeding was the highest in the equivalent standard pollution index of four kinds of pollution source.The total equivalent standard pollution index of Gaomi city was the highest,reached 93.52,this is followed by Changle country,Shouguang city,Changyi city.Finally,the paper concludes that pollution type of livestock and poultry breeding has the highest pollution contribution rate.For the status and types of pollution,this paper put forward some control strategies.
